Title: Foul Shot Jam!
Abstract: In my project I wanted to find out if a basketball player's favorite music affected their concentration. My
hypothesis was that the shooter's favorite music will not affect their concentration. The steps I did were, play the
shooter's favorite music and have the shooter shoot ten shots. After that, have the shooter shoot ten shots to no
music. Write down all th information needed. I concluded that y hypothesis was right. The shooter's favorite music
did not affect his concentration. If I had to do this project again I would use a non basketball player.

Title: Sports and Lung Capacity
Abstract: Lung capacity is the maximum amount of air the lungs can hold when they are fully inflated. This can be
affected by many things, including gender, amount of exercise, height and weight, and more. This project was
intended to learn how playing a team sport affects the lung capacity of middle-school girls. 40 volunteers were
gathered – 20 who played team sports and 20 who did not. Then, a Spirometer was used to measure the maximum
amount of air that each volunteer could inhale. It was determined that volunteers that played team sports did have a
higher average lung capacity than those who did not. The difference between the averages of these two groups of
people was very minimal, though. Further work is planned to determine if caffeine affects the performance of athletes,
or if playing a team sport affects reaction time.

Title: Do Food Labels Affect Taste Preferences?
Abstract: Cholesterol is a major risk factor in Americans. High cholesterol can lead to atherosclerosis, high blood
pressure, heart attacks and strokes. Light ice cream has 50% less cholesterol (animal fat) than its regular
counterpart. The purpose of this experiment is to determine whether groups of men, women, boys, and girls will
detect a difference in taste between light and regular ice cream of the same brand. I also studied whether labeling an
ice cream "light" will affect taste preference. Finally, a no label condition was tested as a control measure. Over fifty
subjects were asked to participate in 3 separate trials to select the best tasting ice cream: correct labels, "switched"
labels (Regular ice cream labeled light, and light ice cream labeled regular), and a no label condition. It was found
that labeling does affect taste preference. This study showed that there is not a significant taste difference between
regular and light ice cream of the brand used.

Title: Do You Like What You See?
Abstract: I am researching the affect of colors on blood pressure. I chose three primary colors and eight participants
of the same age. Each participant will sit quietly for five minutes and have their blood pressure taken. The first color
will be studied for three minutes, blood pressure will be taken and recorded. They will relax for five minutes. The
procedure will be repeated until all colors have been studied and pressures recorded. My data showed red increased
blood pressure, yellow a range of readings and blue decreased pressure. In conclusion, my hypothesis was
somewhat correct, colors affect your blood pressure.

Title: Does Rewarding Students Help Test Scores?
Abstract: Students from various age groups were asked to complete word search puzzles with a "winner" earning a
prize. A second word search puzzle was then presented, however, no prize was offered for completion. The number
of correct words from the two scenarios were then compared and evaluated for all age groups and by gender.

Title: Do False Memories Lead to False Beliefs
Abstract: The purpose is to see how false memories are created to avoid producing false events which lead to
untrue accusations. Give 15 subjects a list of words with a keyword that isn’t on the list,to study for 10seconds.Give a
test with randomly placed words and the keyword to see if subjects think the keyword and other words, were on the
list. Subjects thought the keyword sleep was on the list. The hypothesis does support the conclusion that the
subjects would mistakenly think that sleep was on the test because it related with the other words.When the subjects
were presented with words that never appeared on the original list, subjects recalled that some words were or weren’t
on the list.

Title: Do the Eyes Have It?
Abstract: Do you know someone who can remember anything and everything or so it seems? How do they do it?
To answer this question, elementary students and adults were evaluated as to whether visual or auditory based
information is more easily learned.

Title: Highlight your Mind
Abstract: Does highlighting affect memory? Well that is just what I tested in my experiment. I made a list of twenty
words and highlighted ten of them. I told my subjects to study the list and than write down all that they can remember.
In the end my hypothesis was correct and incorrect. My subjects remembered the same amount of highlighted and
nonhighlighted words. In conclusion highlighting doesn't really help memery. But more testing is needed. Perhaps a
longer word list and more test subjects.

Project Number: MBS010                                           Grade: 7
Title: Game On!
Abstract: I chose this project because I enjoy playing video games and thought it would be an interesting science
fair project. I hypothesized that Setup C would be the best position with volunteers sitting 45 centimeters away from
the screen. In Setup A, volunteers were lying on their stomachs 15 centimeters away from the screen. In Setup B,
volunteers were sitting in a chair, again 15 centimeters away from the screen. My hypothesis was correct. In Setup
C, the volunteers scored the best and were most comfortable. If I were to do this experiment again, I would ask male
volunteers also.

Project Number: MBS011                                              Grade: 7
Title: Does Gender Affect Color Preference?
Abstract: The purpose of this project was to see if gender affected color preference. To find this out, I asked people
to fill out a survey with color-filled boxes on it, and had the, check off their gender and age. I observed that both male
and females like blue best, and yellow the least. So, in conclusion, gender did not have any significant affect on
anybody's color preference.

Title: Are You In Focus?
Abstract: I tested to see if while people are focusing on one thing in particular, if they could also be able to notice
everything else that is going on around them. I first researched how the mind processes information, and the
difference between short-term and long-term memories. I also found tests to use for my experiment. I chose a short-
term memory test, because I believed that I could only use short-term memory to test my theory. I then chose to test
to see how memories differ, from boys to girls. I wanted that to be the only variable. So I tested students in my class,
who were all the same age, but because my class is small I could only ask 6 girls and 6 boys at the most. I thought I
would test anywhere from 8 to 10 students. Since only a few students wanted to participate, I only asked 8 of them, 4
boys and 4 four girls.

Project Number: MBS013                                       Grade: 7
Title: Does Music Impact Mental Focus?
Abstract: Middle school students were tested to determine whether or not music can impact performance levels on
standard word search puzzles. Test subjects were also evaluated on word search puzzle completion without music
as a control.

Title: Memory Games
Abstract: My project is titled “Memory Games.” In my project, I will be testing to see if there is a difference in
memory between boys and girls. I will show a third grade class a group of images and see how many of the images
they can remember after one minute. I will average the total scores of ten boys and ten girls to get my results.

Title: Can you taste that?
Abstract: I did my project to see if girls had a better sense of taste (than boys) when blindfolded. In my hypothesis, I
took an educated guess and said that girls would have a better sense of taste. My planned procedure was to have
the boys and girls put a blindfold on. Then I was to put the food sample in their hand and they would immediately put
it in their mouth. Then they had to guess what the food was. My data showed that girls did have a better sense of
taste than boys. My hypothesis was proven correct.

Project Number: MBS017                                          Grade: 7
Title: Gender and Color Preference
Abstract: My purpose was to investigate whether gender affects color preferences. I gathered my participants and
had them complete a survey where they had to circle which color they preferred from several pairs of colors. Each
participant was taken to the same room and given the same instructions and survey. I found that girls preferred
purple, pink, gray, yellow, and blue. The boys preferred black, orange, green, and purple. I concluded that there is a
gender difference in color preference.

Project Number: MBS018                                             Grade: 8
Title: Music and Moods
Abstract: The purpose of this project is to determine if listening to music affects a person's mood. To conduct this
experiment I will have fifteen human subject's answer a brief mood questionnaire. Then I will have them listen to
music for three minutes. After listening to music, I will have the subject's answer the same brief mood questionnaire.
The experimental results are measured by calculating the results based on a Likert scale to determine if the subject's
mood changed. The Likert scale is a psychometric scale used in research that involves questionnaires. The Likert
scale is used in the pre and post test I gave my subject's. The results of the experiment showed that music did
change the subject's mood. The results indicate that the hypothesis should be accepted because music does affect
one's mood.

Title: Who Has a Better Memory-Boys or Girls?
Abstract: The purpose of this experiment was to determine whether boys or girls had better short term memory. I
chose 10 female subjects and 10 male subjects. Each subject was required to study a test with 20 objects. Each
subject was instructed to memorize or remember as many objects as possible in a determined amount of time. On
average, the girls remembered 10 out of 20 objects while the boys only remembered 9 out of 20 objects. I concluded
that girls, on average, have a better short term memory.

Title: What Color is Your Thirst?
Abstract: My science fair project studied the way color affects people’s perception of taste. My hypothesis was “I
believe that I can affect test subjects' perception of taste by serving the same water from different colored glasses.” I
gave subjects one cup of water of each a red, blue, and green, then had them fill out a list of questions. When asked
which they liked best, blue received about 51% of the votes, with green following at about 35%, and red least liked
with 17%. This supports my original thought that water is best sold in blue bottles.

Title: Specialized Education
Abstract: Today, more than ever, the educational process for “special needs” students is of great importance and
requires intensive research and planning. My work and research was intended to find the best learning method for a
group of special “spectrum disorder” students. I tested the Visual, Auditory, and Kinesthetic education methods by
taking each individual student and teaching them a set skill using pictures (Visual), objects (Kinesthetic), and song
(Auditory). I found that all three student subjects preferred the Visual education method best and they excelled at the
task utilizing the Visual education method more than the Kinesthetic or Auditory methods.

Title: Stop the Noise
Abstract: For my science fair experiment, I tested to see if white noise is an effective studying tool. I gave each of
my subjects a simple memory test with white noise, distracting noise, and no noise, as a control. I found that the
scores were highest on the no noise tests, but higher on the white noise tests than the distracting noise tests, but only
by a very small amount. I concluded that it really depends on the person, but white noise is not an effective studying
tool for most people.

Project Number: MBS023                                           Grade: 7
Title: Can You Name That Color?
Abstract: The purpose of this project is to determine if reading written colors in ink that does not match the color in
word form affects the amount of time it takes to read the word. The procedures include timing the subject on the
amount of time it took to read the words written the word that does not match the ink, then the amount of time it took
to read the words that match. The average for the matching are 6 and the average for the colored are 10. Colors that
matched the word take a shorter amount of time

Title: The Effect of Planned Distractions on Adolescents' Simulated Driving Times
Abstract: In my project the test subjects will play a video game while I will be distracting them. I hypothesize that the
distractions will have a major effect on the subjects. Test 1: Explain to the participant that you will ask him/her
questions and that they should answer the questions to the best of his/her ability. that he should identify verbally Test
3: Explain to the participant that he will be given a series of math problems to complete on a calculator, using one
hand. My conclusion was that my hypothesis was correct and distractions do affect your driving abilities.

Title: Pretty Is As Pretty Does?
Abstract: My project is "Pretty Is as Pretty Does?" The purpose was to find out whether more attractive people are
viewed more favorably. I hypothesized that the attractive people would be seen as more successful, intelligent,
confident etc. I showed my subjects computer-generated faces and asked them to rate certain characteristics on a
scale from one to five. My results proved my hypothesis—the more attractive the person, the more positively they
were judged. The more unattractive the person was the less favorably they were seen.

Title: Inattentional Blindness
Abstract: Does awareness increase as age does? If a person presents the intentional blindness video to 20
students each in 6th, 7th, and 8th grade, then the people who see the gorilla will increase as grade does. Load the
video from http://www.youtube.com/watch?v=vJG698U2Mvo. Show it to 60 test subjects, 20 each from grades 6th-
8th. Start the video. While it’s playing, take down any facial expressions, body movements, etc. When the video ends,
ask them if they saw the gorilla. Record how many saw the gorilla. Compare each grade with each other. To finish,
see what percentage of each grade saw the gorilla.

Title: The Stroop Effect and Emerging Readers
Abstract: It is known that the Stroop Effect has significant effect on adults when they try to name the color of ink that
color words are printed in, but how would children who are still learning how to read respond to this phenomenon? I
tested children in the primary grades by having them read a paragraph with color words printed in different colors of
ink and asked them comprehension questions about the paragraph that were directly tied to color. Results will be on
display at the PRSEF.

Title: Distracted Driving
Abstract: This experiment was done to see if the more the distracted a person is the more likely to cause an
accident. This will give us a better understanding of what not to do while driving. In order to complete this
experiment will need a Wii gaming system and the game Mario kart.
Each race used one of four different distractions. The distractions were eating and drinking, texting, talking, and no
distractions. Each distraction was raced three times. The total time for each race was recorded and then averaged.
This resulted in three data points for each distraction type.
The results showed that driving while texting was the most distracting with an average time of 2:97.390 minutes, and
that the other distractions all were worse than just driving the car. The average time for just driving was 2:21.535
minutes, eating/drinking while driving came in at 2:39.447 minutes and talking on the phone 2: 35.639 minutes. While
this experiment shows the difference in times and that distractions are a problem, it doesn’t show that most of the
extra time was due to accidents and not being able to stay on the road.
This hypothesis was true. The distractions encountered did produce a lower time/score. The more complex the
distraction the longer it took to complete the race.

Title: Correlation Between Relative Pitch and Gender
Abstract: The problem for this experiment asks if males or females are better at singing on pitch. If relative pitch
depends on gender, the females with sing better on pitch. To conduct this experiment, this researcher will ask
students from the age of 11-14 to sign a consent form and sing a series of three notes as I play them on the piano.
Record the results from 100 students: 50 males and 50 females. Compare all results to determine the correlation
between relative pitch and gender.

Title: Warped Words
Abstract: The problem for this experiment asks what way of oddly written words is easiest to read. To conduct this
experiment this researcher will ask students to fill out consent forms before have them take three short, timed tests.
They will decipher as many words as they can in the given time limit. The researcher will record the number of
correctly written words for the three tests for all fifty participants. Compare the average number of correctly
deciphered words for each test to determine what odd way of writing is read easiest.

Title: What Color is Seen Best in Urban Traffic?
Abstract: Purpose: What color is most easily seen in an urban traffic setting?
Hypothesis: The darker dots are easier to see than light dots.
1. Explain the directions to the subject
2. Randomly select the transparency containing the urban traffic setting and the colored dots that will be tested
3. Open a manila folder containing the transparency form step 2 and determine the time required for the test subject
to find the 20 colored dots
4. Repeat steps 1-3 for the remaining transparencies.
5. Repeat steps 1-4 for 29 more test subjects

Abstract: My experiment is about color effecting memory. Get two sheets of paper with black words on one sheet
and colored words on the other (they must be the same amount of letters). Get some subjects that will be willing to do
the experiment. Give the subject the black piece of paper and ask them to memorize it for 30 seconds. Ask them to
repeat the words they memorized back to you. Do the same with the colored words. Record your results.
My hypothesis was that that color would make you remember the words better. My hypothesis was incorrect.

Title: Salts of the World
Abstract: The purpose of my experiment was to see if people can taste the difference between salts. The procedure
used was each subject ate three foods, with one of the four salts, Bretagna Grey Salt, Himalayan Pink Salt, Sea Salt
and Moroccan White Salt, and tell how it tasted. The data I have is that for the Sea Salt: four subjects said it was
strong, one subject said mild. Bretagna Grey Salt: four subjects said moderate, one subject said strong Himalayan
Pink Salt: All five subjects said mild Moroccan White Salt: two subjects said strong, two subjects said mild, one
subject said little.

Title: What Type of TV Show Affects a Teenaged Boy's Heart Rate Most?
Abstract: Watching television can be an enjoyable past time for teenage boys, but is your heart rate impacted by
what you watch? The purpose of the project is to discover what type of television show affects a teenaged boy's heart
rate the most. Twenty participants will watch three examples of three types of age-appropriate TV shows in three
categories: comedy, suspense and documentary. The heart rate of each participant will be monitored three times
during viewing. Results will be available at the PRSEF.

Title: Do Balance Braclets Work?
Abstract: Balance bracelets are bracelets that claim to improve balance, strength, and flexibility. This work intended
to learn if these bracelets truly improve balance. The balance of volunteers was tested by discovering how long each
person could stay on a Bosu ball. Times were recorded before and after wearing bracelets. It was determined that the
bracelets do improve the balance of people. Literature suggests that these bracelets regulate energy flow. Future
work is planned to determine if the Placebo Effect plays a role in the success of these bracelets.

Title: Do you remember what you saw?
Abstract: The purpose of my project is to see if the eye witness testimonies are accurate. The steps in taking my
project are I took them in a quiet room and they watched a movie. I waited five minutes then I gave them a ten
question paper. I calculated the right and wrong of each student and I also averaged it. I concluded that the eye
witness testimonies were accurate.

Title: A Companson of Education Types and Logical Thinking: Phase 3
Abstract: This project expanded on previous research investigating educational differences between Montessori and
traditional education. The purpose of this project was to compare the cognitive skills of students enrolled in different
educational styles and to determine whether one educational style progressed faster into the Formal stage of thinking
as stated by Jean Piaget. The study was carried out using the Group Assessment of Logical Thinking (GALT). The
GALT was administered online through the means of a survey. It was hypothesized that Montessori students would
perform statistically significantly better than traditional education because Montessori uses tactile and interactive
materials to better attend to an individual student’s needs, as well as based on previous experimental results. The
survey included questions about demographics, conservation of mass and volume, probability, and algebraic
concepts. No participant was asked to give their name or any personal information.. Participants gave informed
consent before participating in the study. Data collected form the survey will be analyzed using frequency
distributions to determine whether there is any statistical difference between the education types. A series of X2 test
will be conducted to determine if Montessori students perform better than other educational types.

Title: Gender and Frustration
Abstract: My project will test to see if females have higher frustration levels then males using an electromagnetic
grid. The test will have thirty male and thirty female subjects. They will have three minutes to perform the task and I
will judge their frustration through their responses. Subjects will receive one point for each time they perform a
response (laughing or making jokes, asking for help, aggression, accusations, apathy, sighing, and saying this is
frustrating). Record the number of points they received in the data tables for their frustration levels. Compare results
to determine if my data supports my hypothesis.

Title: Crazy Food Coloring
Abstract: Crazy Food Coloring Abstract
In my project, I was curious as to how a person's judgment would be affected toward eating foods that were
unnaturally colored. I tested ten test subjects in this experiment. Foods included; blue mashed potatoes, red rice,
purple pudding, orange milk, green eggs, and gray/green cake. I collected lots of data and my results varied. The test
subjects were more adventurous then I had expected and had mixed feelings about the food. In conclusion, however,
I found out that people will be willing to try stange colored foods without completely judging them for their color.

Title: reflexezzzzzz
Abstract: The purpose of my experiment was to see the true effects of sleep deprivation. In choosing to do this
topic; I had tested the subject's reflexes by ringing a bell. After the first trial, they were to lose two hours of sleep until
the next testing. After adding all finished times together, and finding averages, my final answer came as a bit of a
shock. The average times for both trials hadn't changed from being sleep deprived or not. Since the times were the
same, my hypothesis was incorrect, thus concluding my experiment.

Abstract: The purpose of my project is to find out which eye color has the best peripheral vision. I predict that the
color with the best peripheral vision will be light blue, because it is more reflective than dark brown. For my
experiment I will run peripheral vision screening tests on a group of ten participants. This group of participants will
consists of five boys and five girls varying in eye color. After the experiment is completed I will collect the data and
prove my hypothesis to be either right or wrong.

Abstract: The purpose of this experiment was to determine which age and gender was most impacted by peer
pressure. The investigator tested 12, 13 and 14 year old girls and 13 and 14 year old boys. The investigator took one
group into a room and gave them a questionnaire orally and recorded the scores. Then, they were given a second
questionnaire and asked to complete it in writing. The investigator determined that the 13 year old boys most
frequently changed their answers and were most susceptible to peer pressure.

Title: Music Therapy: Can it Help the Hurt?
Abstract: The purpose of this experiment is to see if bone marrow biopsy patients feel less discomfort if music is
played during the procedure. To conduct this experiment I questioned the patients after the surgery to ask what their
pain level was. The experimental results were measured by gathering the data into a log book and were then
prepared into graphs. The results of the experiment show that the average pain level for patients that heard music
was less than the average for patients who did not. The results indicate that the hypothesis should be accepted
because patients who heard music seemed to have less pain than patients who did not.

and kill, which is done with a plush toy. For my experiment I had three different categories of toys. The categories
were textures, shapes, and interactive toys. I had four toys in each category and used those to find the overalal
favorite toy. In the end her favorite toy was a plush one.

Abstract: My experiment asked if fear was common in different groups of people. Such as age, birth order or
gender. During my experiment I used survey to question people. I told my participants what my project was about,
and gave them surveys to answer. The data I gathered that children were more afraid of things like darkness. Adults
         Intermediate – Behavioral and Social Science (MBS) – 7th & 8th Grade

were more afraid of monsters. Females were more afraid of animals, and insects. Youngest children were afraid of
insects and darkness compared to middle and oldest children. So fears do common in
different groups linking us constantly together.

Abstract: The purpose of the experiement is to determine if the face plays a role in the attention and awreness of an
observier watching a person demonstrate an action. The experiement will involve a magician and several observers.
The magician will perform a ball and cup magic trick in two different ways: once when only his hands are visible, and
once when his face AND hands are visible. Although observers believe they are only watching the hands in both
circumstances, those who see the face and hands will more likely be "tricked." Final results will be reported once
experimentation has completed.

Abstract: The problem is: Does gender effect color preference?
It is hypothesized that males, ages 11-14, prefer primary colors over secondary colors; while females, ages 11-14,
prefer secondary colors over primary colors. A brief procedure of the experiment is as follows: I will gather all my
materials and write a plan for testing my male and female subjects. I will show to each individual separately color
swabs and ask them to pick their preference. I will repeat this with different subjects and record my data. As I
continue the process, I will also take pictures to support my data. I will repeat this process 4 times. Yes, my hypothes
was supported.

Abstract: The purpose of my experiment was to test which gender was more attracted to a wider variety of certain
scents. To run my experiment I took each of my human subjects into a room, had them smell each of my 12 selected
scents, and rate them on the 9 – Point Hedonic Scale. My results showed that the males and females ranked a “like”
(6 or above on the scale) in 7 of the scents, but the females had a wider range between their likes and dislikes.
Therefore, I concluded that the females were more scent discriminating than the males.

research paper to organize the information collected about the different types of fingerprints. During the experiment,
the participants’ left thumbs were fingerprinted using a fingerprint kit and ink. A spreadsheet was designed to compile
the type of fingerprint each participant had. In conclusion, the data collected supported the hypothesis that children
inherit their fingerprint type from their parents.

Title: Will Plants Grow When Watered by Different Liquids
Abstract: the purpose of my project is to determine if plants will grow when i water them with liquids other than
water. I will be putting different liquids like canada dry general soda, vegetable oil, black coffee, water and cranberry
juice in soil and then checking to see if they grow at different rates. If i use different liquids to water the plants, then
the plants will grow at varying rates. My prediction is that probably only one of the various substances will make the
plant grow and i think that it is the one closest to a water substance like fruit punch juice. The reason why i made that
hypothesis is that fruit punch juice is close to the water and doesn’t have as much acid. Canda dry has the largest
amount of acid with a ph of 5.18 compared to cranberry juice that only has 2.8 -3.0 ph cranberry juice also only has
coloring and fruit juice. However i still think that water would be the best choice.

Abstract: In this experiment, I attempted to find whether or not coffee can stimulate plant growth more than water. I
had four types of beans: Pinto, Red, Soy, and Mung beans. I used twelve of each bean; divided into three sections.
Each different section was watered with a different liquid: Regular coffee, decaf, or water. My data showed that the
water beans grew the best, followed by decaf, and then caffinated. My conclusion is that coffee does not make plants
grow faster, and in fact, restrains plant growth.

Title: Effect of Acid Rain on Plant Growth
Abstract: The purpose of my experiment was to determine if acid rain actually has a negative effect on plants. Two
plants were used. One plant was watered with regular, clean water. The second plant (independent variable) was
watered with acid rain(in this experiment lemon juice). Each plant had a matching spray bottle that contained the
substance they were being watered with. (one contained water; the other contained lemon juice with a pH of 4) They
were watered daily for one week. Both plants started to die, but the plant watered with lemon juice showed more
signs of suffering.

Title: pH Power
Abstract: The purpose of this experiment was to determine if the pH level of soil affects how much a plant grows. To
conduct this experiment, I tested the pH level of two different types of soil. I planted a bean seed in both soils, and
watered each daily. The experimental results were measured in centimeters, and by how much the plants grew. The
results of this experiment showed that the compost soil was a better soil for the bean plants. The compost soil plant
was always taller. The results indicate that I should accept my hypothesis.

Title: The Five Second Rule - Fact or Fiction?
Abstract: The five second rule is a highly popularized myth worldwide; this study demonstrates the risks of using
this dangerous rule. To disprove this theory, marshmallows were split in halves and the dropped on different
surfaces. It was then picked up within five seconds and smeared across an agared petri dish. They were then left to
incubate at a temperature of ninety degrees. The end results would surprise the most avid believer of this myth; many
of the surfaces were unbelievably unsanitary. In the future, testing of more surfaces for bacteria and the ability to
Gram stain the bacteria found is predicted.

Title: Reduction of Stereotypic Behaviors in Polar Bears at Pgh Zoo & PPG Aquarium
Abstract: Polar bears and other large mammals in captivity have exhibited stereotypic behaviors. Zoos across the
world are spending significant efforts and funds to further understand and decrease stereotypic behaviors. The
behaviors of polar bears from the Pittsburgh Zoo and PPG Aquarium were observed over a period of seven months,
using a focal data procedure. The stereotypic behavior of pacing was significantly increased when a polar bear was
isolated from other bears. Pacing disappeared when polar bear interacted with a companion polar bear. The results
suggested that companionship decreased the frequency of stereotypic behaviors in polar bears.

Title: If It's Watered Enough Will It Grow?
Abstract: In this experiment plant one was watered twice a week with one half cup of water. Plant two was watered
once a week with one half cup of water. This was done to see which plant would grow more depending on how often
it was watered. For two weeks the plants were watered accordingly. Then they were measured in inches the week
after they were watered. Plant one grew three inches and plant two grew one inch. Future experiments that could be
done are watering a plant different amount of time per week.

Abstract: This experiment’s purpose is to see if crowding affects plant growth.
To conduct this experiment I gathered bean seeds, six pots, and a measuring cup. I planted some seeds close
together and some in the normal way. I observed and charted data. I measured the plants in centimeters.
The results were measured by growth of the plants. Crowded plants grew better for two trials. The noncrowded
plants grew better for the other. In my hypothesis, I thought the noncrowded plants would grow better for all trials.
The crowded plants grew better for three trials. I disagree with my hypothesis.

Title: Factors Affecting Short Term Memory
Abstract: I did this project because I was interested if age, gender, or education level affects short term memory.
I tested twenty-one participants’ memory by showing them two memory tests; one picture test and one ten word test.
The results showed that age didn’t have a dramatic effect in the results. In both of the tests females had better results
then males and the participants with a lower education level did better on both tests.
My hypothesis has been partly supported and partly denied. I learned that most participants did better on the picture
test than on the words test.

Abstract: Does crossed hand/eye dominance affect basketball shooting percentages? If a group of players that
have crossed hand/eye dominance shoot a number of free throws, then the results will be higher than a group of
players with uncrossed hand/eye dominance shoots free throws. Participants were asked to complete a series of
shoots on a basketball court. Their eye/hand dominance was recorded along with the number of shots made. Data
analysis compared the two groups to determine the effect of had/eye dominance.

Abstract: The problem of my experiment is to see how long the effects of hand sanitizer last. To solve this problem
I’m doing multiple trials to find out. My trials consist of taking bacterial samples from people and testing their sample
at different time intervals, having them put on a consistent amount of hand sanitizer, and I’ll swab their hands at the 5,
15 and 30 min. intervals. Afterwards I’ll place the sealed inoculated Petri dishes in an incubator. After growing them,
I’ll find out how much bacteria was on the swab. Finally, I’ll compare the results to find my answer.

Title: Ready Set Grow
Abstract: My project was developed to determine whether a plant grown hydroponically would develop more quickly
than a soil grown plant.
To begin my project, I did quite abit of research, and developed the hypothesis that hydroponic plants would grow
more quickly. To plant the beans, I had to get sand and soil for growing mediums. The sand requires a nutrient
solution, since it doesn't have many nutrients.
Once I planted the beans, I made sure to water them every day. The beans began to develop very quickly;
however,the hydroponically grown plants grew faster. My hypothesis was correct.

Title: Compost vs Chemical Fertilizer
Abstract: The purpose of my experiment was to determine if compost (organic fertilizer) would work as well as
chemical fertilizer in pea plant growth. I made compost from discarded vegetables from our farm. I grew pea plants in
soil, soil with chemical fertilizer and soil with compost. I compared plant height and color daily. At the end of 5 weeks,
the control (soil) had an average height of 130 mm while the compost average height was 142 mm and the chemical
fertilizer was 126 mm. My hypothesis was supported. Pea plants grown in soil with compost grew taller than those
grown in soil with chemical fertilizer.

Title: Fertilizing Raphanus sativus
Abstract: Fertilizer has high impacts on plant growth, but does not always show positive results. This experiment
was performed to determine if a varied fertilizer application has positive or negative results on radish growth. 300
seeds were distributed into 300 peat pots filled with potting soil. There were 100 peat pots in each of the three
groups. One group remained unfertilized and was watered at the same rate as the other groups, while in the other
two groups the amount given to the plants per weekly period was varied. Growth of the plants were measured in
height, root mass, and plant mass which was then recorded and averaged. The hypothesis was proven because the
group with smaller more frequent doses of fertilizer did better than the group with several large doses of fertilizer.

two identical plants, grown in exactly the same conditions except for the fact that one was enhanced by hormones.
These hormones seemed to make the plants grow faster and bigger. In addition, they also produced a greater yield.
Recently, in China, farmers grew melons that suddenly started exploding due to the chemical furcholorfenuron. They
claim that this enhancer only presents little health risk. But how little is little? Are we willing to risk the health of

Title: Boys vs. Girls Running A Mile
Abstract: This experiment was a way to help myself and others have a accurate answer of who, girls or boys can
finish a mile faster. All the boys and girls gathered in the gym. The girls went then the boys. In the end on average the
boys were faster but some of the girls were faster than some of the boys. Attitude truly does matter some people that
really worked hard did very well the others that didn't care didn't do so well. In the end I enjoyed learning about
runners as I myself am a runner so I leraned more about myself.

Title: Plant Growth
Abstract: The purpose of my project is to determine if gravity affects the way that the roots of plants grow. I will test
this by placing the seed openings in different directions and seeing which way the roots will grow. I will take sixteen
seeds and put them in bags that are marked north, south east and west. I will watch the seeds for a few weeks. Then
after the time is up, I will measure how long the roots grew in each bag and see what direction they are facing. My
hypothesis is I think that if I place the seeds with their opening facing in different directions, then the roots will grow in
the direction that their openings are facing .I think this because it is the easiest way to grow. Also the opening is
straight so the seed will grow straight.

Title: DNA Fingerprinting
Abstract: I will show and discuss how DNA fingerprints are made by the use of gel electrophoresis. DNA fingerprints
are recorded from the migration distance of the dye samples being shown. It relates to the DNA’s molecular size and
net charge. I measured the varying distances the dyes moved in the agarose gel, which depends solely on the
molecular size. I will also discuss how DNA fingerprinting is relevant to Forensics, Biotechnology, and Genetics. I
learned that a person’s DNA is composed of several components.

Title: What Affects Chemical Reactions?
Abstract: By studying substances and the chemical changes that can occur we can better understand chemical
reactions that occur in order to maintain life. 1 or 2 Polident tablets were dissolved in 150 ml. of water at 3 different
temperatures.Ten measurements were taken for each concentration and water temperature and the average reaction
time was reported. The original hypothesis was that concentration and temperature would have an effect on the rate
of the chemical reaction. Increasing temperature led to an increase of the speed in the reaction. Increasing
concentration did not affect the reaction rate.

Title: Will It Chip When You Dip?
Abstract: My experiment asked if a certain kind of nail polish would last longer. During my experiment I asked
family and friends to wear different kinds of nail polish. collect data of what days the nail polish chips and the different
activities they did that day. I also interviewed professional nail artists asking their opinion about the better polishes. I
found out that some polishes have chemicals that cause cancer, but the new nail polishes are made without the
chemical. So do not buy the cheap nail polish from 5 below and claires, but buy the nail polish from opi and insta-dri.
OPi and Insta-Dri are the better ones to go with.

Title: Super Soaker
Abstract: The problem is: by spilling motor oil in water, will sawdust, human hair, sheep's wool, or feathers absorb
the most oil within 24 hours. It is hypothesized that if the same amount of motor oil is spilled in the same amount of
water, then sawdust will clean up more oil than hair, feathers, or sheep's wool. A brief procedure of the experiment is
as follows: Equal amounts of oil and water will be poured into four separate containers marked A-D. Sawdust will be
then placed into container A, human hair in B, feathers in C, and sheep's wool in D. After 24 hours, measurements
will be taken to determine which substance absorbed the most oil. This procedure will be completed three times in
order to verify the original findings. Data will be recorded and analyzed. The results did not support the hypothesis.
Human hair actually absorbed the most oil.

Title: Which Substance Reduces the Acidity of lactic Acid
Abstract: Athletes suffer from muscle soreness and fatigue when lactic acid builds up during exertion. This
experiment determined which substance reduces the acidity of lactic acid with the smallest quantity. 14g of
substances commonly marketed to reduce lactic acid (NaHCO3, CaCO3, MgCO3) were individually added in 0.5g
increments to lactic acid (pH 1.2) and the pH measured. NaHCO3 raised the pH of the lactic acid to 6.6, CaCO3 to
5.7 and MgCO3 to 3.4. NaHCO3 , commonly known as baking soda, reduced the acidity of lactic acid the best.
Further studies can clarify if taking it can help athletes’ performances.

Title: Does This Smell Funny? Ozone vs. Odor
Abstract: My experiment was to work with odors. One hypothesis was that odors could be either masked or
removed. I developed a scale for judging the intensity and offensiveness of the odor. Samples were ranked before
and after two rounds of treatment. Samples were treated with ozone, treated with a masking agent, or control.
The data showed that the masking agent was effective. After two rounds of treatment, ozone was not. When a
smaller treatment area was used, it worked. The odors were both removed and masked. Another conclusion was
that odors are subjective and studying odors can be complex.

Title: The Wrap on Bad Apples
Abstract: My experiment ‘The Wrap On “Bad Apples”’ investigates the differences in permeability of the two leading
polymers—polyvinyl chloride and polyethylene—used in kitchen plastic wraps, to protect food from spoiling. The
investigation includes tests related to oxidation and evaporation. This experiment includes testing wedges of apples
as well as measuring cups of water over time using the two wraps compared to the constant of no wrap. I predict that
polyvinyl chloride is less permeable to oxygen and, therefore, prevents oxidation the best. While polyethylene is less
permeable to water vapor and, therefore, prevents evaporation best.

Title: pH, Sports Drinks & Tooth Decay
Abstract: Recent studies have shown that acidic beverages such as sports drinks and soda have added acids that
can cause demineralization leading to tooth decay. Research showed that the most common acids used in such
drinks are citric, phosphoric, and carbonic acids. This experiment was conducted to see which drink would cause the
most tooth decay. Thirty sterilized teeth were obtained from an oral surgeon. Several homemade sports drinks were
included in this study. Before the experiment was started the mass of the teeth was taken using a digital balance and
the pH of each drink was taken with a pH meter. The teeth were soaked in the 9 different acidic drinks and the
control group, water, for 1 week. After soaking for one week, each tooth was taken out, the mass of the teeth was
taken and the pH of each beverage was measured. The mass of each tooth was again taken and the pH recorded.

Abstract: The purpose of this experiment is to find out how fast paint dries. To do this, 3 mediums (fabric, poster
board, and canvas), temperatures (70º, 80º, and 30º), and types of paint (acrylic, tempera, and fabric) are selected.
The procedure is to paint three different mediums with five different colors of paint (red, yellow, green, yellow, blue,
and white) in the three different temperatures. The paints are checked until dry at selected time intervals, recording
the observations and time data. The paint that dried the fastest in this experiment was the white tempera paint, in the
70º room , on fabric.

Title: Wine be Gone
Abstract: The purpose of my experiment is to find which carpet cleaner cleans the best out of four options. I first
poured the wine on each carpet sample and then cleaned the sample accordingly to the directions on each cleaner.
The Resolve® cleaner performed the best, getting most of the samples clean. The Woolite® performed very similar,
showing few stained samples. The Spot Shot® cleaner was the third greatest, having few clean but not horribly
stained samples. Austin’s® performed the worst, leaving some of the samples stained. In conclusion, I found that
Resolve® showed the best results.

Title: Ice Cold
Abstract: The goal of this experiment was to freeze four different temperatures of water to find out if hot water
freezes faster than cold water. Sixty milliliters of water, heated to selected temperature, were placed into cups. Then
the samples were placed in the freezer and checked every ten minutes until the temperature reached 0 degrees
Celsius. The results were that the hot water temperatures drop faster than cold. However, they take a little longer to
freeze. Further experiments could test why 75 degrees Celsius took the longest to freeze.

Title: How Low Can You GO?
Abstract: Instant cold packs are a great way to treat minor bumps and bruises. This experiment is intended to
question if changing the amount of ammonium nitrate dissolved in water will affect temperature. The measurements
of .5, 1, 1.5, 2, 2.5, 3, and 3.5 g of ammonium nitrate were dissolved in 50 ml of water seven times. Those seven
trials were repeated. A thermometer was used to measure the temperature in degrees Celsius before starting, every
15 seconds, and when the temperature stabilized. The results show that the samples with more ammonium nitrate
got the coldest.

Title: Antacids on pH of Gastric Juice
Abstract: Antacids are commonly used to prevent and treat an upset stomach, heartburn, GERD (Gastro
esophageal reflux disease), and indigestion. Three trials were conducted for each of the 10 Antacids tested and the
control group, water. (33 trials in all). The gastric juice was heated to body temperature. The pH was measured and
recorded every 20 seconds for 10 minutes and the average was taken of each the 3 trials. Equate with calcium
carbonate and magnesium hydroxide raised the pH of the gastric juice most effectively and fastest. This experiment
can be used to help people to know which antacid to take if they need a fast, effective result to alleviate pain.

Title: Meltdown
Abstract: Ice build-up during winter months can cause hazardous conditions on steps and sidewalks. If ice can be
melted quickly these problems could be eliminated. The purpose of my project is to determine which material will melt
ice faster as a replacement for rock salt. I collected snow, melted it and re-froze it. I put one of my experimental
materials; fertilizer, gravel, rock salt or sea salt on my ice samples. I placed the samples in the freezer at varying
temperatures to determine which would melt the ice best. Results indicate that sea salt melted the ice fastest
regardless of temperature.

Title: Temp. on Chemiluminescence
Abstract: Based upon research on chemiluminescence, this investigation studied the effect of temperature on
chemiluminescence as determined by the duration of glow time and intensity of light emitted from four colors of
chemical light sticks. Four light sticks of each of the four colors were housed in water baths of the following
temperatures: 0, 10, 20 (room temperature), 30, and 40 degrees Celsius. To measure the light sticks, the investigator
created a closed system of her own design. The luminescence of each light stick was measured at 1-hour intervals
for 8 hours and recorded. After activating the light sticks, to slow down the chemical reaction, housing them in
freezing temperatures will lengthen the duration of the luminescence. Also, increase of temperature maximizes the
intensity of the light stick’s luminescence. Miners, firefighters, and those working with hazardous chemicals and
explosives would find the results of this experiment crucial because light sticks act as their sole light source in these

Title: Let It Rise
Abstract: I chose to highlight chemical leavening, the chemical reaction of baking soda and an acid releasing CO2
gas. I attempted to prove a dry, acidic ingredient would cause a slower chemical reaction and cause the greatest
leavening in a cupcake. Cupcakes were made using a common recipe including baking soda and 3 different acid
ingredients. The height of the cupcakes were measured and compared to a control trial made without an acid. The
data showed that all cupcakes with acid did rise higher than the control. The results showed that the dry acid
ingredient caused the largest amount of leavening.

Title: Forensic Chemistry
Abstract: The problem is: Does lugol's iodine, iron nitrate, and sodium hydroxide help to identify unknown crystals
dissolved in water?
It is hypothesized that, by adding iron nitrate, sodium hydroxide, and lugol's iodine separately into each substance, a
particular color will identify the substance.
A brief procedure of the experiment is as follows: I will put distilled water in a reaction plate, and then dissolve four
different solutes in each ones assigned row. I will then add the appropriate chemical to each row. Then I will record
the data, and repeat five times.
The results did support the hypothesis.

Title: Antacid Tablets, Liquids, and pH Levels, Oh My!
Abstract: The purpose of this experiment is to see if the pH levels of different liquids are affected by antacid tablets.
To conduct this experiment I will place an antacid tablet in several liquids and use pH strips to record the ph level.
The experimental results were measured by observing to see if the pH levels of the liquids changed by placing
antacid tablets in them. The results of the experiment concluded that the pH levels of the liquids either decrease by .5
or stayed the same. The results indicated that my hypothesis should be accepted because the pH levels changed or
stayed the same.

Title: The Greener Drain Cleaner
Abstract: Commercial drain cleaners are corrosive to the sewage system, polluting our rivers and water supply.
While visiting ALCOSAN’s Open House about waste water treatment last fall, I found that household chemicals are
discharged into our rivers. This led me to investigate which drain cleaner unclogs blockages most effectively and
causes least damage to the environment. By replicating blockage material, completing multiple trials with varying
blockages, and testing pH and Turbidity of the resulting mixture, I concluded that the home solution of a baking soda
and vinegar combination cleared blockages best and was the least harmful to the environment.

Title: I Ran Out of Batteries
Abstract: Batteries are very important, so why waste it on stuff that does not require so much of it? Three kinds of
batteries were "invented," two of the three succeeded in powering an led light but required more quantity to power
things with higher voltage (the voltage was measured). The batteries were made from food, as an advantage of it
being available forever. One was called the "potato battery," "film canister battery," and a bigger replica of the film
canister battery called the "container battery." The batteries are working today and future work will determine how
long the batteries last.

Title: How Temperature Affects Glow Sticks
Abstract: Glow sticks were put in the freezer, refrigerator, and boiling water while one was left at room temperature.
They were broken and put back into the condition they were started in (i.e. put back into boiling water after broken,
etc). Time was recorded when light was extinguished. The hotter the temperature of the glow stick, the brighter the
glow but the shorter the time until the glow was extinguished.

Title: Fuel of the Future
Abstract: My experiment was to determine if new or used oil makes a better biodiesel. The process started with
research before creating the biodiesel. This included titrating, mixing Sodium Hydroxide with Methanol to create
Sodium Methoxide, and then creating the biodiesel. I tested using the 3/27 test as well as a cloud test. The new oil
was better; it made more biodiesel per 100 mL of oil proving my hypothesis correct. The used oil made quality
biodiesel. However, it required more oil to make the same amount of biodiesel. This means less oil contaminating soil
or going into landfills.

Title: Hydrogen Under the Heat
Abstract: The purpose of my experiment was to see if the temperature that a hydrogen fuel cell was running at
would determine how long it would run. I obtained a fuel cell, then tested it in three different temperatures cold, hot,
and room temperature. To test the hot temperature, I just put the fuel cell in a cardboard box with a light turned on.
To test the cold temperature, I put the fuel cell in the refrigerator. Then I tied how long it took for the fuel cell to stop
spinning the motor that it was hooked up to. In the end my hypothesis was correct that the fuel cell would run longest
at room temperature.

Title: Fizzy or Flat?
Abstract: The whole goal out of this experiment is to see what most common types of pop go flat the fastest and
why it goes flat. My conclusion is that Mountain Dew stays fizzy the longest. The reason why all the other pops went
flat was because of carbonation. When first pour out pop from a bottle it fizzes. That’s because of the carbon dioxide
in the bottle. When you open it the gas is released but when it’s closed the gas stays inside. If you let pop stay out it
gives it time for the carbon dioxide to escape causing it to become flat. That is my project on pop and Carbonation.

Abstract: The conversion of solar energy to hydrogen by electrolysis is a very interesting ways to achieve clean and
renewable energy systems. This experiment was intended to observe how efficient a cobalt-based catalyst can be at
helping to form molecular oxygen and hydrogen, that produce heat and electricity. A circuit was built on a
breadboard. Nickel electrodes were immersed into a pH7 phosphate buffer. Cobalt nitrate was added to the buffer
solution to form a catalyst. The baseline efficiency, without the catalyst, was compared to the baseline efficiency with
the catalyst. We found that more electricity could be produced with the catalyst rather than without.

subject showed that the dyed hair was either the same or stronger as the untreated hair. The results did not support
the hypothesis because the data suggested that instead of chemically damaging the hair, the strands were equally
strong or stronger.

Title: The Magic of Photochemistry
Abstract: The purpose of this experiment was to investigate whether incandescent, fluorescent, a grow light or LED
light would have the biggest effect on the chemical reaction of iodine-ammonium-oxalate. To conduct this
experiment, I must set up a place where each test tube solution I made can be exposed to one of these lights without
interruption for 5 hours. I will compare them to a scale of standard solutions I made, numbered 1-6. The
experimental results were measured and as I predicted, the grow light faded the solution the most. The results of the
experiment show that the grow light faded the solution the most. Fluorescent light faded the solution the second most,
and the incandescent and LED lights barely faded the solution at all. These results indicated that my hypothesis
should be accepted.
I think this project is important because it will help people be a little more educated about the importance of light in
our everyday lives.

Title: Finding BPA in Thermal Paper
Abstract: Humans frequently touch receipts. The purpose of my project was to find if the chemical Bisphenol A
(BPA) is found on thermal paper, the material receipts are printed on. Bisphenol A is a very dangerous chemical that
causes breast cancer and other disease, and skin proves no barrier to it. In order to test each receipt, I used Iron 3
Chloride and a cotton swab to determine if each receipt was positive or negative. It was determined that most of the
receipts were positive; no significant amount of receipts were negative. In the future, people should be cautious about
touching receipts.

Title: Honey, I Extracted the DNA!
Abstract: The purpose of my experiment titled “Honey, I Extracted the DNA!” is to learn about the DNA of living
things. I will use an extraction buffer of salt, dishwashing detergent, and water to extract the DNA from strawberry,
kiwi, and split pea samples. I will crush each sample, add the extraction buffer, and later add ethanol to each and
observe. The DNA should appear in cotton-like fibers. I will compare and contrast the DNA from each sample. I
hypothesized that strawberries would produce the most DNA because they have large genomes and are octoploid,
meaning they have eight copies of each chromosome in each cell.

Title: The Great Cookie Finder
Abstract: Have you ever bitten into a beautiful golden-brown cookie only to realize that the bottom is burned and
black? I conducted this experiment to find out how to prevent that. I started by making the cookie dough with all the
ingredients, I used an ice cream scoop to make sure all the cookies were the same size. I preheated the oven to 375
degrees, I let the cookies bake for 14 minutes. The cookies cooled for 4 minutes for each batch, then I recorded what
I saw. Conduct my experiment for yourself and see what results you get.

Title: Brownie "Egg"stravaganza
Abstract: My experiment was run to test whether the addition of eggs in a brownie batter would increase or
decrease the density of the brownies. I had baked twenty batches of brownies, having five different variations with
different amounts of eggs in each variation. I had recorded any observations of the brownies, including the mass and
height of each batch, and had then calculated their densities. My results showed that the density of the brownies
had a slight decrease with the addition of eggs. Therefore, eggs add volume to brownies and decrease their density.

Title: Mirror, Mirror on the Wall, Which Water is the Purist of All?
Abstract: In case the PDF is not working:
The water we drink comes from different sources, such as taps, springs, filters, and boiled. Which water is the purest
for consumption? My project addressed this question by looking at seven common contaminants. Water test kits were
used to conduct experiments. The results varied. Spring water has no bacteria, lead or chlorine, has low hardness
and neutral pH value. Tap and filter water had more nitrite. No chlorine or lead was detected in any water. Bacteria
were found only in boiled water. I conclude spring water is the purest.

Title: Citrus Power
Abstract: Electricity can be conducted by some substances more easily than others. The purpose of my project is to
determine which citrus juice, lemon, lime and orange, conducts electricity best and if additives like sugar, salt and
vinegar support electron flow. I added equal amounts of sugar, salt and vinegar to equal amounts of each type of
citrus juice and used a Centech Digital Microscope to measure electrical current. Results indicate that salt, when
added to citrus juices, allowed electric current to flow more readily than other additives.

Title: How to Make the Best Cookies
Abstract: The purpose of my project is to determine if I can make the best cookies by making the cookie mix and
having it sit in the refrigerator for 48 hours. I am going to make a batch of cookies and refrigerate the batch for 48
hours. After 48 hours, I will make another batch of cookies. I will then bake both batches. I will have three
volunteers to taste the cookies to see if they prefer cookies refrigerated or freshly baked. I will also measure the
sizes such as the length, width, and height. If I make the mix and have it sit in the refrigerator for 48 hours then I may
have better cookies.

Title: Tumor Diagnosis with Image Processing
Abstract: I wrote a computer program to help doctors diagnose tumors. It takes an image of a stained tissue
sample, extracts and analyzes the relevant sections, and outputs a final score. I separated sample images into a test
set and a verification set. I researched different image processing algorithms to extract relevant sections and created
programs using combinations of these. I also developed my own analysis and score computation algorithm. I tested
each program on the test set. My final program produced scores with a very strong correlation with the expert ratings
for both the test set and the verification set.

Title: What Type of Password Best Resists Hacking
Abstract: The purpose of this experiment is to determine whether a password should be longer or more complex to
resist brute force cracking. 60 people each contributed 9 passwords of varying length and complexity. An original
brute force cracker was written in C++, but was too slow, so a model was made to crack the 540 passwords
gathered. The data showed that increasing the length was more beneficial than increasing the complexity. This
supported my hypothesis that longer passwords would take more attempts because there would be more possibilities
for the program to try before it could identify the correct password.

Title: Computer Simulated Billiards
Abstract: The purpose of this experiment was to find which angles of shots terminate in a pocket from a billiards
shot originating in a corner. To conduct this experiment I designed a billiards table using Logo programming
language. I shot 90 different angles from each different corner for a total of 360 shots. The experimental results were
measured by whether the shot terminated in a pocket or not. The results of this experiment were that of the 360 shots
14 went in a pocket. The results indicate that my hypothesis should be accepted because the angles 30, 50, and 60
didn’t terminate in a pocket.

Abstract: My project was designed to assist people in more effectively and efficiently using cell phones by exploring
what factors have the greatest impact on cell phone transmission signal strength. Before I performed my experiment,
I predicted that topography, including man made obstructions, would have the greatest impact on cell phone signal
strength. In conducting this project, I analyzed a variety of factors including what effect distance from cell phone
towers would have on signal strength, what affects various locations within in a typical building would have, and what
other forces generally impact transmission signal strength.

Abstract: The purpose of this experiment was to determine which furnace filter cleans the air the best. The
investigator tested 3 furnace fliters of varying costs (Flanders EZ Green filter, Filtrete Micro Particle Reduction,
Filtrete Advanced Allergen Reduction). The filters were tested over two, 5-day trials with the furnace fan running for
24 hours a day. The mass of the filter was determined before and after each trial using a triple beam balance. The
investigator determined that the second most costly filter--the Micro Particle Reduction filter removed the largest
number of particles and the Micro Particle Reduction filter was the most cost effective--that is, it removes the most
harmful particles per dollar.

Title: Durability of Paint
Abstract: Painting your home can be very expensive. Knowing the most durable paint could help consumers save
money in the future. I used 6 types of paint in this investigation: Behr paint (which is the most expensive) latex gloss
and flat, Valspar paint (much less expensive) latex gloss and flat, and Glidden paint (in between in price) gloss and
flat. I painted twenty-four 12.7cm x 12.7cm square plywood boards with the different kinds of paint. I put aside the
control boards. I then put the different boards through various weathering stations of heat, freezer, and acid rain.
They were rotated through the stations for 12 days. I calculated the amount of chipping using an overlay
transparency, which was the same size as the board and had 200 graph squares. Chipping in 2 squares was
counted as 1 percent chipping. When results were analyzed, Behr paints, the most expensive, were found to be the
most durable, possibly because of the higher amount of titanium dioxide.

Title: UV Protective Fabrics
Abstract: UV light is radiation with wavelengths shorter than visible light, but longer than x-rays. Even though it is
not visible, it can still be harmful. Overexposure to UV light can cause skin damage such as sunburn and skin cancer.
Skin cancer is the most common form of cancer in the United States. About 45% of people who live to be 65 years
old are diagnosed with skin cancer at some point of their lives. You can protect yourself from this damage, however,
by wearing the proper material clothing. In this project, the amount of UV light that passed through the different
fabrics was tested. In conclusion, it was decided that the red polyester and the black 50% polyester 50% cotton
fabrics performed the best. Over all, the polyester fabrics performed the best, the 50/50 did the second best, and the
cotton did the worst. Also, the darker the fabric, the better it performed.

Title: Taste the Difference
Abstract: I wanted to find out if people really could taste the difference between reduced fat and regular foods. i
tested a total of 30 people between the ages of 10-69; five people from each decade. i picked out foods from the
different areas of taste buds on the tongue; sweet, salty, bitter, and sour. The food I picked for sour was salt and
vinegar chips. The seet food was ice cream. i chose Cheez-its for the salty food. i picked chocolate wit a lot of

Title: Show Me Those Pearly Whites
Abstract: Whitening toothpastes are used to make teeth appear whiter. This experiment was chosen to find out what
whitening toothpaste will perform the best. 36 teeth were obtained from an oral surgeon and stained with tea for one
week. Next, they were separated into 9 different groups, 4 teeth in every group. I recorded the shade of the teeth
before and after every brushing. I brushed each tooth exactly the same – 25 strokes, 2 times per day. The results of
the trials were averaged. This experiment showed that Arm and Hammer Whitening Toothpaste whitened the best.
Arm and Hammer performed the best because it contains a large amount of Sodium Bicarbonate (Baking Soda).
Baking Soda helps whiten teeth because it dissolves into the water and penetrates the enamel, when brushing the
baking soda removes the yellow and brown stains usually caused from coffee, tea, or smoking.

Title: Paper Towels and Water Absorption
Abstract: The purpose of this experiment was to see which paper towel absorbs the most water. Three brands
Sparkle, Brawny, and Bounty were tested. My procedure was to dip a paper towel into a measuring cup that was filled
to 250 milliliters of water, and see how much each paper towel would absorb. Measurements taken after each trial,
five trials per sheet were compiled on a graph. My conclusion was that Bounty was the most absorbent paper towel of
the three that were tested.

Title: Air Care
Abstract: The reason for my project was to see which filter consumers should purchase. I bought three filters, then
weighed each filter before I placed them into the furnace, then I took the weight difference between each filter,
concluding that the ending weight was equal to the amount of particles the filter strained. I predicted that the "Filtrete"
filter would strain the most particles because the company claimed to be the best. The brand "Filtrete" strained the
most particles. Its starting weight was 189 grams, and its ending weight was 190 grams. The other filters' weight
decreased, proving my hypothesis correct.

Title: Chill Factor
Abstract: I conducted an experiment testing if temperature effected how long a battery would last. I was interested
in this topic because of car batteries. It is true that car batteries most of the time stop working in cold weather. I
decided to test this. I could not test this on a car battery so i decided to test it in the form of a flashlight. My
experiment went as planned and nothing out of the ordinary happened. As i suspected the flashlight in the freezer
stopped working first. Next i suspected the flashlight in room temperature would stop working. I was wrong and the
flashlight in the refrigerator stopped working next. This left the flashlight in room temperature.

Title: Preventing Christmas Tree Fires
Abstract: Christmas tree fires can be catastrophic, and my experiment will determine if flame retardant sprays
(commercial and homemade) will effectively prevent fires. Three fresh branches were tagged and sprayed with
commercial flame retardant, three were tagged and sprayed with homemade flame retardant, and three were tagged
and left as control branches. One of each was burned at twenty-four hours, eight days, and fifteen days and time to
ignition was recorded. The time to ignition was similar for all treated branches and only slightly less than untreated
branches. Flame retardant spray has minimal value to prevent fire in well watered trees.

Title: Effect of Settling on Cereal
Abstract: The objective of the project was to see how cereal settles. Many people complain that a lot of the cereal
bag is empty. This is because air fills in between the pieces of cereal after it is packaged. The cereal is packaged to
the top though. The process was to crush up the cereal and measure it against the un-crushed cereal. The height
changed, but the weight did not.

Title: What is the Best Paint for Polystyrene Model Kits?
Abstract: The purpose of my experiment was to compare different paints from different manufacturers to see which
are best for ease of use, durability, price, and environmental friendliness.I applied stress to the paint samples and
compared results. In some cases, I used documentation about the paint to also get results. The best paint was found
to be acrylic with use of water for clean up. Enamel paints required harmful cleanup materials which were more
dangerous to the environment. Comparing more samples from other companies and running more trials
might have strengthened the results.

Title: Keep It Cool
Abstract: My question for my project states: "Which insulation is the most effective for your home?" From my
research, I hypothesized that spray foam would be the most effective insulation because it forms an airtight barrier
and is denser than most other insulations. To determine which insulation will keep ice from melting, I tested seven
different insulations enclosed in containers and measured th e amount of melted water found in each measuring cup,
which was located under each container. After seven hours, the cup that colected the least amount of melted water
determined the best insulation. My results showed styrofoam had the least amount of water in its measuring cup.

Abstract: The purpose of this project was to see which storage temperature would be the best to store popcorn
kernels, to get the popped kernels. I had three storage areas, room temperature, refrigerator, and warmed in an oven.
I kept them there for 2 hours. The better storage area was room temperature. So if you want to get more popped
kernels out of a bag of popcorn, the best place to store it is in a warmer area.

Title: Which paper towel brand can absorb the most water?
Abstract: The purpose of the experiment was to find which paper towel brand could absorb the most water. I ripped
four sheets from each roll. Then I put them in a glass filled with 200 mL of water for 15 seconds. I squeezed all the
water out into a glass and measured how much each sheet held. Bounty could hold an average of 38 mL of water,
Brawny could hold 30 mL of water and WalMart's generic brand could hold 22 mL of water. Brawny was the best buy
for consumers since it absorbs the most and has the most number of sheets.

Abstract: For my science project I tested the effects of household cleaners on fruit. I did this because I wanted to
see if these cleaners had any effect on the fruit I eat since I use these cleaners to clean my counter tops. For my
procedure I took the cleaners Mr. Clean floor cleaner, The Works glass cleaner, Great Value glass cleaner, Febreeze
and water. I then cut up some apples and placed them into 6 even groups, and added a small dose of each cleaner
for ten days. By the end the Mr. Clean had caused the most discoloration.

Title: Pepsi versus Coke
Abstract: My purpose for choosing to do this project was because I like Coke and Pepsi, so I wanted to see what
other people think. I prefer Coke over Pepsi. But other people may choose Pepsi. So I decided to do an experiment,
to test the hypothesis: In a blind taste test, Coke will be chosen more frequently than Pepsi. Each taster signed the
consent after i explained the experiment to them. I gave them an answer index card and had them drink from the "A"
labeled cup first, and then drink from the "B" labeled cup. They then checked their answer card which one they liked
best and wrote either Pepsi or Coke beside the A and B letters. After all this I recorded all of my data. Surprisingly,
neither product was preferred over the other nor was the nubmer of incorrect identifications higherin comparison to
the correct identification. Age made no difference in the ability to differentiate between the products. In conclusion, I
was surprised by the results as I felt that Coke would win hands down each time or at least take the lead in being the
preferred product. My hypothesis was not proven based on my results that each product was preferred 50/50.

Title: Do Green Food Savers Work?
Abstract: I decided to do this project because I wanted to see if a reusable food saver would be just as effective as
a common household food saver. I cut pieces of apple and put them into Tupperware containers and covered each
with Press and Seal wrap, Reynolds wrap, reusable food saver, and nothing, which was the control. I observed the
apples over the course of two weeks, and found that the reusable food saver was the best food saver, which was
surprising. This research shows that an environment friendly food saver worked better than a common household
food saver.

hypothesis was that if you use x amount of water on the regular plant, you would save that much. I was wrong,
actually you might only save half of what you usually use, but it still saves water.

Title: The Amazing Affect of Weather and Temperature
Abstract: This project was designed to see how temperature and weather affect a rubber band. The project was
made to see where the best place to store rubber bands is. To test the experiment one must put rubber bands in
different places with different temperatures. Colder temperatures make rubber bands the most elastic. In further work
on can test how temperature and weather affect different things

Title: Plastic or Metal, What's Best for the Earth?
Abstract: The environment is a hot topic these days. Much work can be done to identify how different products
affect our Mother Earth. This experiment was conducted to test and compare two products-a hair dryer and a toaster,
on their eco-frienliness. The objects were disassembled and in turn placed into the ground for one month to test for
corrosion and decay. The toaster had emitted corrosion unlike the hair dryer. Future work will determine the "green"

Title: Chemicals and Biodegrading
Abstract: I searched to find which chemical when added to a substance produced the most methane gas. I placed
three substances, corn, a banana, and a piece of newspaper, in a plastic container. I added the appropriate
chemical, lime juice, alcohol, and compost maker, to each substance and sealed the top. I connected a tube from the
container to an upside down water bottle filled with four hundred milliliters of water. I recorded my data for fifty days
marking how much methane each substance produced. I concluded that lime juice produces the most methane gas
when added to a substance.

Title: Natural Gas Drilling and Water
Abstract: Oil and natural gas are a big part of a new generation of cleaner fuels. Although they are “clean” fuels,
many people say otherwise. They file complaints about their water being contaminated and point the finger at natural
gas wells. A recent study by Penn State says otherwise. Since the wells are surrounded by thick layers of concrete
and steel there is practically no chance of anything escape the well. The average well for water ends at around 150 to
250 feet. The average natural gas well ends at around 5,000 to upwards of 11,000 feet. If anything should happen to
leach out it would be far too deep to affect any water well. My project will determine whether or not natural gas wells
are affecting our nations drinking water.

Title: Melting Ice
Abstract: The purpose of my project is to see what substance makes ice melt the fastest. I am going to test it by
placing 1 ice cube on each plate and sprinkling 2 tablespoons of each substance on 1 ice cube. Next I will start the
stopwatch immediately to time how quickly the ice has melted after 1 minute. I will measure how low the ice has
melted. If I use different substances then the ice will melt at different rates. My prediction is that salt will melt ice the
fastest because people use road salt to melt ice all the time in the winter.

Title: The Earth's Energy
Abstract: I wanted to see if more energy is produced using a power plant verses geothermal reservoirs.
I used a can with two holes to represent the power plant. The boiling water represented the geothermal
resevoirs, the aluminum foil the earth's crust, and a pinwheel represented the turbine so I could
measure the amount of energy produced.
I learned that a power plant is necessary in order to produce more energy.
I concluded that more energy is produced when the power plant is used. More holes caused less energy.
Therefore, geothermal power plants are needed to increase energynproduction.

Title: "Hair-Gone Crazy"
Abstract: Does your hair go crazy when the weather turns rainy? My question is, "Does different hair strands
change as humidity varies?" I hypothesized that chemically treated hair will absorb the most moisture on humid days.
I built a hygrometer and tested the humidity outside using different hair strands; chemically treated hair, curly brown
hair and straight blond hair. The hygrometer was placed outside on days when the temperature reached 72, 40, and
30 degrees. All results were recorded.
Humidity was absorbed in all three types of hair. It was concluded, temperature and hair type has an affect on how
much humidity is absorbed by human hair.

Title: Composting - A Better Quality of Soil
Abstract: Composting speeds up the natural process of decomposition, by providing conditions that are best for
breaking down organic and improves the quality of dirt. The presence of Nitrogen in soil may determine the quality of
that soil. This project will compare traditional composting involving dirt, water and organic waste with
vermicomposting which is composting using the traditional method plus worms. Nitrogen levels will be measured at
the start of my project and again at 3, 6 and 9 weeks. The amounts and types of organic matter added to the
composts will be identical. Results will be presented at the PRSEF.

Title: Ways To Kill Stink bugs
Abstract: For my science project i was determined to find out a way to kill the increasingly residential and
crop/garden destructive stink bugs that have taken over areas in northeastern United States. I tested ten different
products on the stink bugs by putting the bug in a baby food jar with a chemical. The stink bugs died a different
amount of time in each chemical. By the end of the experiment I found that the stronger the chemical the more slowly
the extermination was completed, which is the opposite of the hypothesis I declared in the beginning.

Abstract: The purpose of this experiment is to test if electricity can be generated from a homemade microbial fuel
cell model. To conduct this experiment I built a model of a microbial fuel cell and tested the voltage daily. To measure
the voltage I used a digital multimeter. The results were that it did generate electricity. My results did agree with my
hypothesis which stated that if I make a homemade microbial fuel cell then electricity will be generated.

Abstract: The purpose of this project was to create a low-cost solar system capable of powering small devices. I
chose this project because of my interest in renewable resources. First, I searched to find how solar panels work.
Then, I searched for similar designs on the internet. I finally began to design. Next, I will create my first prototype, and
test it on small electronics. Finally, I will retest and redesign to create the most practical product (my design will be
available on fair day). To further my research, I will create more solar products, and expand their uses.

Title: What does Acid Rain Do?
Abstract: Does acid rain destroy plants? This project shows how acid rain degrades the growth of plants. I found
out whether dicot and monocot plants show any difference when exposed to acid rain. I studied what different pH’s
do to the heights and dry masses of plants of the two classes—dicot and monocot. I tested the pH’s 6.8, 5.0, and
2.0. After the experiment, I found out that pH decreases the growth of the plants. As the pH decreases the plants’
heights and masses deteriorate as well.

Title: Effect of Household Cleaners on Plants
Abstract: Pollution is a major factor in the environment. Brown water, the mixture of chemicals and detergents from
the washing machine, are often not disposed of properly. When this occurs it can cause harm to many things. To
show this I grew beans from the seed for 15 days watering them every other day with only water. For the next 15
days each group was watered with a different chemical but the same amount liquid. Each group had 3 plants. The
results had a negative effect on my bean plants.

Title: Are There Ways to Manage Water?
Abstract: The goal of my project was to find inexpensive ways to control excess rainwater. To complete this project,
I evaluated three methods of controlling excess rainwater. The methods I chose were tunnel reservoirs, green roofs,
and permeable pavement. I interviewed representatives for the Allegheny Green Roof, the Allegheny County
Sanitary Authority, and the Pennsylvania Department of Transportation. I then tested samples of permeable
pavement, bituminous pavement, green roof soil and substrate, and roofing shingles to determine the amount of
water each sample was capable of holding. I then researched and calculated the cost and water absorption amount
for each method.

Title: The Power of Acid
Abstract: My experiment is based on what would happen if plants got acid rain as a main supply of water. The
normal ph of acid rain is 5 to 7. Mine uses ph of 1 to 3. My experiment is based on what would happen if air pollution
(what causes acid rain) would continue. If the air pollution continues then the ph of acid rain would get higher. My
hypothesis is that the plants are going to grow more slowly and the acid rain will weaken them enough so that a lack
of untainted water killed them. My hypothesis was true.

Title: Solar Panels
Abstract: The purpose of this experiment was to see how background color affects solar power. Do solar panels
work better on a white or black background? A simple and safe solar powered electrical circuit was designed to
operate a light bulb, a fan, and a siren. It was found that solar panels worked more effectively on a white background
than a black one. This experiment can be applied in studies of energy and engineering.

Title: Cause and Effect: Save the Coral, Save the Earth
Abstract: Coral makes up eight percent of the Earth's surface, and is a habitat. Coral death is becoming prominent,
and the potential for disaster and coral death stimulated me to find the cause of coral death and a natural, non-toxic
prevention. Through research, I found that the most likely causes of coral death were a temperature change, a
salinity, acidity, and nitrate increase, and a resultant Cyano HAB-algal bloom. I tested each factor, comparing each to
a control. Throughout this procedure, I found that all of these were at the root of coral bleaching. At this point, I found
that my control was coated in red slime algae, which is extremely detrimental to the coral, existing in surplus,
triggered by pollutants. Through experimentation, I found a cage of clay, activated charcoal, and hydrogen peroxide
to be effective in getting rid of the algae, creating a ratio of 6:3:1, respectively

Title: Stink Bug Repellent
Abstract: Stink bugs are small, flying bugs that eat crops and let off unpleasant smells. In my experiment I tested
five different stink bug repellents to see which was most effective. I chose this project because people were being
infested with these bugs in their homes. My experimental setup had three lanes, and at the end of each lane was the
repellent. On the other side of the lane was alcohol, the control. After 15 minutes I measured the distance the stink
bug was away from the repellent and concluded soapy alcohol worked best.

fifteen days the average growth was 17cm (no magnets), 17.7 cm (magnets under) and 17.2 cm (magnets above).
After thirty days the average growth was 12.1cm, 20.6cm, and 16.5 cm respectively. My hypothesis, if magnetic
fields affect plant growth then the plants will grow faster because the magnets will affect the minerals in the soil, was
supported by the data.

Title: Crazy Crystal Creations
Abstract: The purpose of this experiment was to analyze how temperature affects the crystallization of Borax. The
crystals were placed in a refrigerator, at room temperature, and in an ice bath. It was hypothesized that the crystals
would grow better in cooler temperatures (the refrigerator), because in order in order for the saturated water to regain
solubility and crystallize, the temperature must be cold. Crystals seemed to grow the best in the coldest temperature.
Environmentalists and earth scientists would be interested in these results.

Title: Sizing Up the Moon
Abstract: I did this project to discover whether or not the apparent changing of the moon’s size is illusory. I took
various quantities of data, such as angle from the horizon and temperature, and took photographs of the moon. Then,
I measured how many pixels tall the moon was on a paint program, and compared the size of the moon with the other
data. I did not find a correlation between angle and the size of the moon. Then, I can conclude that the changes are
illusory. Further research includes seeing if other factors might affect the size of the moon.

test the water, I used an aquarium testing kit. I have found normal levels of pH in the water sources. In the coming
days, I plan on comparing the data I found in the water to data I found about pH levels before Marcellus Shale drilling
began. This will show me how much the Marcellus Shale drilling has impacted our waters.

garbage bags. Then, I dropped each parachute 10 times from a 388 1/2cm high balcony, and used a stopwatch to
time how long it took each one to drop to the ground. I recorded the results and my data showed that my hypothesis
was correct.

Title: Maximum Fiber Optic Bend Radius
Abstract: A fiber Optic cable is a very thin strand of glass used for transmitting data in the form of light. The fiber
optic cable is transparent and no smaller than a single human hair. Five brands of fiber optic cable were tested. In my
project I found which brand of fiber optic cable has the greatest tolerance for light transmission when bent. I came to
conclude that the fiber optic cable Lucent had the greatest tolerance for the light. This would benefit anyone installing,
or using fiber optic cables in modern times. Most fiber optic cable are installed and used in wire closets. These
closets keep getting filled up and sometimes the cables have to be bent just to fit. With the results of this project, you
can know exactly how far is too far to bend these cables.

Abstract: Potential energy is the energy that is stored in a system. Kinetic energy is the energy of motion and
movement. The results of potential energy compared to kinetic energy depend on many different variables which
affect the velocity and distance of motion. My researched topics for potential energy transformed into kinetic energy
were the computer, Dictionary, Encyclopedia, and a science top 20 magazine. I went on 3 different websites for the
computer research: Kinetic Energy, Understanding Potential and Kinetic Energy Hypothesis, and Studying Potential
Energy. I also researched encyclopedia to understand the relationship between potential energy and kinetic energy.

Title: Rushing Water
Abstract: In my project, I am testing to see if the size of a hole in a tidal barrage effects how much hydroelectricity is
produced. To test this I have built a tidal barrage with three different sized holes. I will measure the amount of
hydroelectricity that is being produced in various ways to support my outcome. I will count the rotations of a propeller
of each hole, how long each hole powers a light bulb, the flow rate of each hole, and I will use the power equation
P=eHQg to determine the total energy output of each hole.

Title: Increasing the Elasticity of Rubber Bands
Abstract: Given a package of #64 rubber bands, could I manipulate the bands to make one shoot farther, and retain
its elasticity longer? I manipulated the rubber bands in five ways. I soaked the rubber bands in 34°, 61°, and 150°F
water, heated them in a 170° oven, and cut them down to half their width. The oven heated rubber bands shot the
farthest on average. The half-width rubber bands shot the shortest on average.

Title: Testing the Poundage of Fishing Line
Abstract: Testing the Poundage of Fishing Line
I took 6lb test fishing line and took 5lb of weight, tied the fishing line on the weight and pulled the line up with the
weight, it held so I put more weight on the line until it broke. Then I took two 6lb fishing line and put doubled the line
and tested with weight to see if it would hold double. I did this with a line folded in 3. The line did not double or triple
it’s holding ability.

Title: Spin Right Round
Abstract: The purpose of my project is to determine how the number of coils affects how quickly a motor spins. I will
make motors with different amount of coils in order to see which spins the fastest I will measure the speed with a
voltmeter. If I build three electric motors, one with 10 coils, one with 30 coils and one with 50 coils, then the motor will
spin at different rates. I think that the motor with 50 coils will spin the fastest. The reason why I think the motor with
50 coils will spin the fastest because I think that it makes more electricity.

Title: Salt Water: Alternative Energy?
Abstract: Desalination is the process of removing salt from seawater so that it can be used for drinking and
irrigation. However, this process has many problems such as using extreme amounts of energy, being very
expensive, and the chemicals used are harmful to the environment. In this experiment, 11 metal electrodes were
tested in a 20% and a 40% salt concentration, measured in volts, then the top 2 metals were measured in amperage,
and the top metal was doubled to show the effect of different salt content in various sea waters. It was determined
that magnesium performed the best in a 40% salt concentration and doubled. Therefore, it is theoretically possible to
power the desalination process using salt water. This would be known as “Regeneration” or “Re-gen” for short.

Title: Best Insulation for Clothing
Abstract: Thermal insulation is the reduction of heat transfer. Insulation for clothing is necessary to prevent
hypothermia. This work intends to determine the most effective fabric for use of insulation. Four different fabrics were
compared: Cotton, Under Armour, Fleece, and a Cotton/Polyester mix. To test which fabric provides best insulation,
temperature change was compared between a container wrapped with a test fabric and a control container. It was
determined that Fleece was the best insulator, because it yielded the least temperature change.

Title: Suspenseful Potential
Abstract: My experiment is to test if the gravitational potential energy of a coaster will have to be greater than the
kinetic energy it needs to complete its track. I hypothesized that the potential energy will always be greater than the
kinetic energy. In my experiment, I made three tracks using foam pipe insulation. Then I measured how high the
starting point was and how long the track was. Then I got the mass of a marble, let it run down the track and
calculated it velocity. Using these measurements, I calculated the amount of energy for both types in joules. I
realized my hypothesis was proven correct.

Title: Soaring High
Abstract: The purpose of my project is to determine which wing design creates the most lift. I am going to do this by
creating six different wing designs. They will be a conventional straight wing, a swept-back wing, a swept forward
wing, a delta wing, variable swept wing, and a flying wing. I will test all of them to discover which one creates the
most lift. I will do this by first creating the wings out of plywood, then placing them at a thirty degree angle on top of
wooden supports. Next I will slide the wings into a wind tunnel. Then I will begin to periodically add weights onto the

wing until it goes under thirty degrees. I believe that the delta wing will create the most lift. I believe this because they
have a large wingspan and are used for military aircrafts.

Title: The Effects of Aerodynamics on Paper Gliders
Abstract: My experiment is on the effects of aerodynamics on paper gliders. My purpose is to see which plane is
better, an omniwing (single wing plane) or a standard plane. My hypothesis is to see which plane will fly farther and
better. I used three different planes, a control, an omniwing, and a standard plane. To test my planes I used a tape
measure to measure the distance and a stopwatch to time them. After I got the time and distance I found the
average of both planes and announced the winner of that day. That is how I tested.

Abstract: If I use more bottle caps on my wheel will the wheel spin faster because there is more flowing water and
increase power? My project is to show how energy is created through flowing water. I decided to do this when I was
researching different things to pick my topic then I noticed a ling to a video of a water wheel. It looked like it would be
very fun to build so I picked it. I hoped to achieve success by getting the water wheel in motion but then I figured out
this was going to be hard. But knowledge will increase when you experience failures so I would not give up.

Title: Solar Panel Efficiency Comparison
Abstract: My science project is going to test various ways to increase solar panel efficiency. I will be conducting
three tests. First however I will be assembling the solar panel from scratch. After that I conducted the tests. These
were cooling the solar panel, using mirrors to angle more light onto the solar panel surface, and mathematically
angling the cells of the solar panel to get the optimum light intake from the sun. These tests will be performed on
three different days with the same solar panel. Once the tests are done I think hypothesize that using mirrors to angle
light will increase solar panel efficiency the most. I will reach this possible conclusion by measuring the energy output
and voltage.

Title: 15 Miles on the Erie Canal
Abstract: A makeshift calorimeter, which measures heat, was made up of a cup and a foam lid. Inside was an
eggbeater pedal suspended in 200 milliliters of water. A drill press was used to turn the eggbeater at 620 rotations
per minute. The eggbeater pedal rotated in the water, and the water temperature fluctuated. A temperature probe
was inserted into the cup before testing and remained throughout to graph the temperature rise. The data was
collected on the computer program Logger Pro and recorded. The results show that when water is subjected to more
mechanical energy, the thermal energy increases accordingly.

Abstract: The purpose of this experiment is to find which surface a homemade hovercraft glides the best on.
To conduct this experiment i constructed a homemade hovercraft and placed it on three different surfaces.
The experimental results were measured by finding the mean of several trials.
The results of this experiment showed that the tile surface was the best for the hovercraft to glide on.

The results indicate that the hypothesis should be accepted because the hovercraft did have the least amount of
friction and glided easily on the tile surface.

Title: How Much Electricity Could Be Saved By Using Smart Technology?
Abstract: The purpose of this project was to determine whether energy saving devices really work and how many
watts, CO2 and money you could conserve per month and per year by using them. The investigator tested a lamp
using a CFL and an incandescent light bulb. The investigator measured both light bulbs with the Belkin Conserve
INsight. The investigator measured watt and CO2 output and also the cost. The investigator repeated the same steps
using a television with and without an energy saving power cord. The investigator concluded that an energy saving
light bulb saves you money, CO2 output and watt output but that the power cord had little impact on the watts, CO2
and cost of using the television.

Title: Building a Stronger Bridge
Abstract: The purpose of this project was to demonstrate the difference in strength between bridge designs.
This project compared 3 different bridge designs (Simple Beam, King Post truss, and Warren Truss). I used the
following steps: 1) Build three bridge designs out of balsa wood, 2) hang a bucket from the middle of each bridge, 3)
add weight to the bucket until each bridge breaks.
As more supports are added to a bridge the stronger it becomes. As expected, the model bridge with the most
supports was the strongest. The Warren Truss held 6 times as much weight as the Simple Beam and e times as
much as the King Post Truss.

that is scattered. I think that the crumpled cylinder would scatter the most light. I made this hypothesis because the
cylinder that’s crumpled has lots of creases that could make the radar not send back accurate reading.

energy produced by the power source and the energy after going through a 5V regulator. If was found that batteries
lost about 1/3 of their energy while solar panels and generators lost about half of their energy. Batteries are less
durable and therefore more costly even though they work best.

Title: Frozen Again!
Abstract: The purpose of this experiment is to solve the problem of my goat’s water freezing during the cold winter
nights. When the water is frozen the goats cannot drink and their milk production plummets. Our family depends on
the milk from our goats. I will be testing the insulative properties of four different materials; rice hulls, straw, fiberglass
insulation, and wool fiber. For each of the four materials, I will be using two used tires, stacked upon each other, filling
their cavities with one of the materials. The control will be two stacked tires with empty cavities. Then placing a
bucket of water inside of each, I will record three temperature readings in the evening, and then measure the
temperature differences. My initial results pointed to the rice hulls and fleece being equal at maintaining the water
temperatures. One definite result was my control showed that tires alone add an insulative effect compared to a
bucket of water just sitting outside of the tires. I am still collecting data so my final Abstract and results will be
available on Fair Day.

Title: Comparative Woodburning Temperatures
Abstract: The problem is: what type of wood can create the highest temperature in a certain amount of time? It is
hypothesized that the wood that is largest in size, and has the thickest bark will generate the highest temperature. A
brief procedure of the experiment is as follows: Put the wood in the stone and cast iron wood burning stove.
Positition and light the fire starter making sure the wood has caught fire before closing the door. Once the wood has
caught fire and door is closed, shut the flu properly and set the thermometer to measure every few minutes for
approximately 5 minutes. Repeat the process five times for each type of wood. Observe and record data.
My hypothesis was supported.

Abstract: How do machines calculate square roots? Although computers and calculators contain special pieces of
hardware that directly perform addition, multiplication, etc., they typically calculate square roots either through
software or through logarithmic lookup tables. In my project, I have designed a new hardware-only machine that
uses digital logic (e.g., AND and OR gates) to directly compute square roots without using lookup tables, using the
digit-by-digit method on binary numbers. I have implemented a prototype of my design on real hardware using an
FPGA (Field-Programmable Gate Array) development board, and I have evaluated tradeoffs between speed and
hardware cost.

would make it stronger. My hypothesis was correct my data showed that when the bridge was widened vibration
decreased. It also showed that when handrails were added the vibration decreased.

shields were made using removable fabric pouches to cover metallic fabric inserts. Additionally, a see-through shield
material was attached to each bottom shield in order to protect the user from EMF emissions over the entire surface
of the laptop. The homemade shields blocked over 99% of laptop EMF. The homemade shields were more
economical and unlike commercial shields, provided protection over the entire laptop.

Title: Go, Solar Car, Go!
Abstract: The purpose of my project is to see how the angle of sun rays affects the speed of a model solar car. First
I have to buy and build a solar toy car. Then I get a flash light and angle it at different angles to determine how they
make the toy car move. Next I will time the speed of the car. I will make sure the flash light is at the same distance. If
I took those steps I would find out if a certain angle would affect the speed of my solar car. I think that if change the

angle the speed would be different. I think a 45 degree angle will make it go faster because it is a lower angle and
closer to the car.

Title: Tooth Enamel Staining by Beverages
Abstract: This project tests which commonly consumed beverages cause the most discoloration or staining of tooth
enamel. Cups are filled with either milk, water, coffee, black tea, grape juice, Coke, green tea, or red wine. The pH of
each beverage is measured. An egg is placed in each cup and allowed to soak for various time intervals. After each
time interval, the amount of discoloration of the eggs are measured and compared. Eggs are used to simulate tooth
enamel because eggshells have similar mineral content. The more acidic beverages caused the most staining.

Title: Whose Mouth is Cleaner? - A Dog's or a Human's?
Abstract: The problem for this experiment asks whether a dog’s or a human’s mouth is cleaner. If bacteria colonies
are grown from human and dog samples, then the cleanliness of the mouth can be determined. To conduct this
experiment this researcher will ask peers to fill out consent forms before taking swabs of the mouth. Collect the
swabs, and then lightly rub all swabs into separate Petri dishes. Petri dishes will be sealed after inoculation, and
incubated. After the colonies have grown, compare the color and number of bacteria colonies to determine whose
mouth is cleaner.

Title: Most Effective Acne Medication
Abstract: The purpose of my experiment was to see which acne medication is most effective in killing acne causing,
Staphylococcus epidermidis bacteria I will test my experiment by taking a circular piece of paper soaked in the
diluted antibiotic, and placing it in the center of a section of a Petri dish rubbed with Staphylococcus epidermidis.
After four days I will measure the inhibition zone that formed to determine the effectiveness of the acne medication. I
observed and concluded that Clindamycin Antibiotic had the largest inhibition zone followed by Benzoyl Peroxide and
then the Tetracycline Antibiotic.

Title: Herbal vs. Synthetic
Abstract: The purpose of this experiment was to see if tea tree oil or erythromycin would inhibit more bacteria. First,
pipette 3 l of staphylococcus aureus onto each agar plate, then poke four holes in each of two plates, and place four
erythromycin discs on the third one. Fill one plate’s holes with tea tree oil, and fill the other’s with sterile water. Place
them in an incubator and record data at 24 and 48 hours. My conclusion supported the hypothesis, in which it was
predicted that tea tree oil would work better than erythromycin.

Title: Bacterial Resistance
Abstract: The purpose of this experiment is to make people aware of current bacterial resistance. To conduct
experiment, spread three bacteria species on each plate and place four erythromycin disks on each plate. Allow the
bacteria to grow and record all data. Remove the bacterial colony closest to the disk and re-culture for next
generation. The data collected showed that all bacteria became less instead of more resistant to erythromycin which
was unexpected. The hypothesis was incorrect because the bacterial species became less instead of more resistant
to the erythromycin antibiotic.

Abstract: The purpose of this experiment is to determine whether spices inhibit bacterial growth and if so which
spice is most effective. Triptych soy agar plates covered in Escherichia Coli, containing for holes filled with oil spice,
were put in an incubator at 37 degrees centigrade. The zones of inhibition around each hole were measured at 24
and 48 hours and data showed that all of the spices inhibited bacterial growth. However coriander had a significantly
larger zone of inhibition at 22.1 mm. My findings on coriander can be used for medicinal purposes and cures in the
prevention of harmful bacteria and disease.

Title: Reckoning the Effectiveness of the Flu Vaccine
Abstract: Influenza is caused by a RNA virus, which frequently evolves into different strains by constantly changing
its nucleotides. Every year the World Health Organization recommends vaccine strains by guessing the next year’s
virus strains. As the vaccine is developed by prediction, its effectiveness varies yearly. This project will analyze the
past 10-years' flu vaccines' effectiveness. The H protein sequences from vaccines and circulating virus strains will be
compared to find the vaccine efficacy. A correlation graph will be generatedby plotting the percent sequence identity
against the number of people hospitalized with flu symptoms, and will be used to estimate the effectiveness of the
current (2011) flu vaccine. I’m still conducting my experiment. My final abstract will be available on Fair Day.

Title: Hand Sanitizers vs Antibacterial Wipes
Abstract: Hand sanitizers and antibacterial wipes can help prevent disease and illness from germs transferred by
the hands. This experiment was intended to find out whether sanitizers or hand wipes would most inhibit bacterial
growth. Paper discs soaked in 7 sanitizers and 7 antibacterial wipes and sterile water. They were then were placed
on agar plates streaked with E. coli, S. epidermidis, and M. luteus. Four trials were conducted for each
sanitizer/wipe/control for each bacterial strain. The 90 agar plates were placed in the incubator for 72 hours at 37
degrees Celcius. Plates were removed, zones of inhibition were measured, and the results of the four trials for each
were averaged. Hand wipes inhibited more growth than sanitizers. Also, Baby Ganics sanitizer and CVS hand wipes
inhibited bacterial growth the best. These both contained Benzalkonium Chloride as the active ingredient. Future
work is planned to test more strains of bacteria.

Title: Effects of Alcohol
Abstract: My purpose was to determine the effects of alcohol on a random group of people. Tequila was given to
participants followed by acuity testing at regular intervals. I learned that alcohol affects people differently, depending
on age, height, weight and gender. As hypothesized, most participants’ tests results declined. The results were as
expected. I knew alcohol affected people and this experiment showed me exactly how. This project would be
beneficial to bars and restaurants to help detect excessive drinking. For a future experiment, I could use different
types of alcohol and run more tests for more precise results.

Title: The effect of exercise on sleep
Abstract: Abstract                                                       The effects of exercise before bed.
While knowing sleep and exercise are both important for enjoying good health, research is unclear about exercise
before bed having an effect on sleep and then on the performance of a person the next day. This project intended to
see if exercising before bed would have a positive effect on sleep due to fatigue from exercise as well as increased
performance the next day due to a good night’s sleep. My research suggests that the best time to exercise is 60-90
minutes before bed – that exercise closer to bedtime may lessen the amount of restful sleep.

Title: Fun in the Sun
Abstract: Ultraviolet (UV) radiation is considered the main cause of skin cancer. People often think that the only
parts of their skin that are at risk of being damaged by the sun are the parts of skin that aren't covered by clothing.
They assume that clothing - of any kind - protects their skin completely from the sun's UV rays. But this is not true.
Because the ozone layer is slowly weakening, our skin is even more in danger. That is why I tested different fabrics
to see which would protect your skin from UV rays the most. I found that dark colored cotton fabrics blocked UV rays
the most.

Title: Are Brand Drugs Better Than Generic Drugs?
Abstract: The purpose of my experiment was to find out the difference between generic and brand drugs and which
is the most effective for stomach upset. The problem was: “Is there a difference between generic and brand drugs?
Which type is more effective for stomach upsets?” It was hypothesized that famous brand drugs are more effective
for stomach upsets, because they are manufactured in big facilities, are popular, safer, and have higher prices. It
was found that there was no significant difference between generic and brand antacids, regardless of regular pH or
different pH conditions. These results will definitely help consumers as they will save money when buying generic
drugs. Also doctors can recommend generic drugs to their patients.

Title: Relax With Yoga
Abstract: For the experiment, blood pressure was tested after yoga was done. There were three participants that
did yoga three times a week for three weeks. Their blood pressure was measured to see how yoga affects it. And
there was one participant that blood pressure was taken to compare with the other participants. So after doing that,
the results were that blood pressure decreases over time when yoga is done. Further tests can be done on how
different yoga moves affect blood pressure.

Title: Stretching and Throwing
Abstract: Stretching is a practical warm-up before a game. The purpose of my experiment was to show that
stretching will increase the distance of a throw. Three partners ,along with myself, threw from a starting point without
stretching. Then, we performed a series of dynamic stretches and threw again. We repeated my experiment a total of
five times but, we also did five days of throwing twice but not stretching at all. We did this to show the effects of
stretching. The stretching had a positive effect on the throws.

Abstract: I provided an untouched pen to a pediatrician's office, a family physician’s office and an ER center for five
days. The receptionist was in charge of monitoring the pens. After receiving all the pens back, each pen was
swabbed and placed on a Petri dish. I waited 30 days and examined the dishes under a microscope. I recorded the
data. My hypothesis was incorrect. The Petri dishes from the pediatrician’s office had nearly double the volume of
bacteria from the Petri dishes then the ER dishes. When was the last time you cleaned the pen you are using right

Title: Does Weight Training Increase Running Speed?
Abstract: I looked at different ways to increase running speed and decided to give weight training a try. The purpose
of my assignment is to see if weight training and leg training will improve my current speed in a 36.58-meter dash.

The procedures that I used are the following. I measured 36.58 meters with a tape measure on a field. I ran and
recorded time with a stopwatch. I performed weight-training exercises once a week. I ran and recorded running times
to monitor progress. The results proved the hypothesis to be successful. Increased leg muscle strength directly
affected running speed. The more weight added, the faster the time. Weight training strengthens the cores muscles
used in sprint running. The strengthening of those would impact speed. Weight training and leg training will
accomplish the goal.

Title: Do Shoes make the Athlete?
Abstract: The purpose of this experiment was to find out what shoe design showed the best performance for the
athlete. To conduct this experiment I used Adidas Running Shoe, Nike Running Shoe, Nike Skater Shoe and Bare-
feet. To conduct the experiment run 100yards and see which time was faster for four trials for each shoe. The result
was that bare-feet had the fastest time out of all the shoes. The hypothesis was supported by the data collected
because the hypothesis stated that there will be a direct effect on the performance due to the design of the shoe.

Abstract: The purpose of this experiment is to find out if Manuka Honey with a higher level of UMF will inhibit
bacteria as well as one with a lower UMF. First, the agar plates were spread with bacteria and pipetted with honey,
then placed in the incubator for 24 and 48 hours and then measured respectively. Four trials were conducted to
make the experiment more accurate. The conclusion was that Manuka Honey UMF 20 did indeed inhibit bacteria
better, which was supported by the experimental data.

Title: Music: Can it Really Help a Sick Dog?
Abstract: The purpose of this experiment was to discover whether or not music therapy would help dogs better
tolerate chemotherapy. I used a double-blind controlled design where dogs were randomly selected by veterinary
technicians to either hear music or not during chemotherapy. The technicians and the dogs’ owners rated each dog’s
calmness, affection, and cooperation on a standardized scale before and after chemotherapy. The technicians also
measured vital signs before and after chemotherapy. Averages and histograms of the changes in scores showed the
music had no effect on behavior and vital signs. Thus, my hypothesis was disproven.

Abstract: The purpose for this experiment is to find out which exercise I picked out that worked the best to raise
heart rate. The investigator used different cardiovascular exercises and had volunteers do them. The investigator
took the volunteers' radial pulse, recorded it before and after exercise and continued the process with all volunteers.
The investigator waited ten minutes until having the volunteer do the next exercise. The investigator totaled up all the
numbers to see which exercise raised the heart rates the most. The investigator concluded that the squat thrusts
raised the heart rates the most.

Title: To Oil or Not to Oil
Abstract: I did this project because I barely understand the topic of how oil effects how a bowling ball spins and
travels. I had hoped to be able to see the results more clearly and understand it more. To do this I had two bowlers
try out two patterns, one with a lot of oil on the lane and one with absolutely none. My results showed that the heavier
oil was more unpredictable than the lighter oiled lane. I had predicted that the heavier oil would cause more spin and
less travel however my results showed otherwise

Title: Ready, Set, Release!
Abstract: The experiment’s purpose is to see if I can consistently throw the ball in a specific spot of the strike zone
depending on my release point.

Make a target wall and place behind home plate. Make a grid wall; place beside pitcher. Throw a variety of pitches.
Record them.
My results show that the earlier you release the ball the higher it crosses home plate.
My hypothesis was supported. The earlier you release the ball, the higher it will go. This helps people improve at
pitching. Next time, I would use a black ball and a stronger target wall.

Title: Thermal Conductivity in Metals
Abstract: Metal is a very significant part of one's life. Metal is ubiquitous in our world and can be seen everywhere,
from buildings to frying pans. Therefore it is very important to evaluate different metals thermal conductivity values.
Teh thermal conductivity value is important because it allows engineers or astro-scientists to find a material that could
insulate objects in outer space, where it could be boiling hot or freezing cold. The lower the thermal conductivity, the
better the material insulates. For my project, I will experiment with three metals: copper, steel, and aluminum. I will
measure how far rhe heat will move through the wires, in intervals of 20 mm. I will try to find out in which metal the
heat travels farthest the fastest. This metal will have the highest thermal conductivity.

Title: How Gear Ratios Change the Amount of Work Done
Abstract: The purpose of this experiment was to see how gear ratios change the amount of work done. Start by
measuring the diameter of the front gear being used. Tape a wooden stick to the side of the bike for a solid starting
point. The piece of tape on the tire will track the distance it traveled. Do one rotation of the front gear and see how
many rotations the back wheel does. Next, do five rotations to see how many rotations the back wheel does. Do this
for two more gear settings and compare the results. Then, predict three rotation results. The investigator determined
that an increased gear ratio results in more work being done.

Title: How Green is Your Light Bulb?
Abstract: The purpose of this experiment was to see which light bulb (compact fluorescent, LED, halogen or
incandescent) has the best energy efficiency and lowest cost. Each bulb was hung in the center of a hula hoop. Light
was measured at equally spaced spots on the hoop. Efficiency was calculated by dividing lumens by watts. Overall
cost was calculated by summing the hourly cost of the bulb and electricity cost in kwh. Results show that compact
fluorescent and LED bulbs have better efficiency and lower overall cost than incandescent and halogen.

Abstract: The purpose of my project is to predict where nodes are on guitar strings. First I will measure the string
then I will predict the first, second and third node for the string. Then I will play the node and measure the frequency
with an electric tuner and record. I will then compare the frequency that I recorded with what the frequency really
should be. My hypothesis is that if I play different harmonics I will get different wave patterns or frequencies while
playing the first three nodes. I think that I will be able to accurately predict the frequencies for each node. I think this
because I have been studying a lot of websites like guitar-chords.com

Abstract: My question is: Which liquid has the highest viscosity? I hypothesized that syrup would have the highest
viscosity based on my research. First, I got a clear pipe and put a cap on the end of it. I marked off two lines, one
near the top and one near the bottom. I filled the pipe up with liquids. I dropped the marble. When the marble
crossed the first line I would start a timer. I stopped the time when rthe marble crossed the second line. I did this
three times for all four liquids. My hypothesis was incorrect. Dishwasher liquid had the highest viscosity. If I did this
experimet again, I would use a shorter pipe and test liquids at different elevated temperatures.

investigator was used in testing. Utilizing the prosthetic foot (on loan from University of Pittsburgh School of
Prosthetics and Orthotics Lab) and this RPK devise ensured that the kick was exactly the same with each trial. Four
brands of soccer balls (Nike, Umbro, Puma, Adidas) at three different air pressures (low, medium, high) were tested.
There were 3 trials for each condition. Results were then averaged. It was determined that the Umbro soccer ball
traveled the farthest in the medium and high air pressure category. This experiment was conducted to see what air
pressure we should use for our school soccer team.

Abstract: I tried to see if adding other substances to water would change its freezing point. I got my materials. I put
different substances and water into each container. I froze them and saw if the water or other liquids froze first. I
learned that it takes a long time to freeze water and longer to freeze salt-water and less time to freeze sugar-water.
This means that to freeze something in a shorter amount of time, add sugar. I knew that freezing salt takes pretty
long but I didn’t think it would take as long as it did.

inserting them to a depth of 1 cm. The nail was knocked in using a measured weight and the screw was screwed in
using a lever attached to a fishing scale and turned by hand. The nail and the screw were pulled out by attaching
weights to a pulley system. My hypothesis was correct.

Abstract: The purpose of this experiment was to determine whether the temperature of water affects the time in
which it takes to freeze. The experiment was conducted by heating a beaker of water to one of four initial
temperatures, putting the beaker into the freezer, and then monitoring the temperatures every 5 minutes. There were
three samples for each initial temperature. The data was then recorded and the average temperatures were plotted
on the graph. The hypothesis was supported by the data. The initial temperature of 30 degrees Celsius was the
fastest to freeze.

onto a Lego and real block wall from a measured height and recorded the data. The Lego brick wall accurately
modeled the scale force needed to break apart the joints on a real block wall. The Legos did not accurately scale the
compressive strength of a real block or the force needed to break the face of a real block.

peeled off. I recorded the weight of how much it took to make the tape peel off. Duct tape stuck to glass the best.
Masking tape stuck to wood the best. Masking tape stuck to fabric the best. Duct tape stuck to metal the best. Metal
was the surface all tapes stuck to the best.

Title: The Diameter Makes the Image
Abstract: The purpose of my problem is to figure out what diameter length of a magnifying glass could project an
image onto a piece of blank paper. The procedure that I used was first off shining the light onto the object and moving
the magnifying glass in between the object and the paper. My hypothesis was that I think that the bigger the diameter
is, the closer it is to the object and father away from the paper. I developed this thought because usually the bigger it
is, the clearer the picture will be in the end.

Title: The Mpemba Effect
Abstract: The purpose of my experiment is to find out if hot water freezes faster than cold water. To do my
experiment I would test 100 degrees Celsius, 90 degrees Celsius, and 80 degrees Celsius and 70 degrees Celsius
water. First I would measure 150 ml of water into a beaker and label the temperature. Then I would heat the water to
the correct temperature. I would then pour the water into the beaker and cover it and place it in the freezer and record
the time. I would check it often. When each beaker becomes frozen I would record the time, weigh it and repeat the
experiment for each temperature. I think the hot water would freeze the fastest because the MPEMBA Effect says
that:” Hot water freezes than faster”?

Title: 0- 80 Will The Song Remain The Same?
Abstract: I am going to be a professional guitarist. I want to know how different temperatures and weather
conditions effect my guitar and playing. Would my song remain the same in hot, cold, room, and humid
environments? Using a guitar-to-computer interface, my guitar, a MacBookPro, and a Garage Band app, I played a
G,C, and a D, in 4 different environments. Before each trial, I tuned my guitar precisely in room temperature.
1. Room Temp-69 degrees, In tune
2. Hot- 84 degrees, Stayed in tune
3. Cold-30 degrees, 10 cents sharp
4. Humid- 77 degrees, 10 cents flat
Conclusion: Cold and humidity effected the guitar the most.

Title: How does flex affect accuracy and speed?
Abstract: For my science fair project I tested to discover which hockey stick flex was better for accuracy and speed.
My hypothesis was that the higher flex stick would result in greayer accuracy and speed. I started by using 3 different
flexed sticks. My father helped by being my second shooter. I recorded the data from the slap shots speeds and how
many targets we could hit. Then I found the average of the slap shot speeds and the percentage of our accuracy. In
conclusion the appropriate flex depended on strength, size, and other variables.

Title: Solar Energy: Does more light produce more energy?
Abstract: Solar energy is a clean and alternative form of energy source. I wanted to find out what effect the amount
of light exposure had on the solar energy produced. I used three light bulbs with different lumens namely 360
lumens, 630 lumens, and 1380 lumens. I shined each bulb using a desk lamp onto two solar panels that

were connected together to an ammeter. I recorded the energy produced in milli-amps unit using each bulb.
I found that the 360 lumen bulb produced 49.4 milli-Amps, 630 lumen bulb produced 100.7milli- Amps and
1380 bulb produced 231 milli- Amps. I graphed the outcomes in a line graph with lumen power on the x axis
and milli-Amps on the y axis and discovered that there was a linear relationship between the two entities.
From the pattern of the graph, I predicted that there will be decreasing amount of energy if there is a lower
lumen power light bulb and experimented using the bulbs of a lumen of 205 produced 36.7 milli-Amps.
The outcome of my hypothesis was correct. I concluded that as the lumen power of the light bulb increases,
proportionally more solar energy is produced. In the future, if we use more solar panels, we will save money
and protect the environment.

curved? From the information I have gathered, it would most likely be able to reach speeds of 75 mph! That’s about
the speed of a car on the Kansas Turnpike! That means if you were the goalkeeper, the speed’s would be like a
speeding car coming right towards you.

Abstract: This experiment was conducted to find the light (LEDs, fluorescent, incandescent or halogen) with the
least fading effect on fabrics. Boxes were constructed with light, and a strip of each fabric (wool, cotton, satin, silk,
polyester, canvas, and linen) at the bottom. Black dye was evenly applied to the fabrics. Strips were compared with
a grayscale. Data collected shows that LEDs had the least fading effect on all fabrics except silk, and incandescent
and halogen lights had the greatest effect on all fabrics except silk. It is concluded that LEDs are the best light for
preserving fabrics’ color.

the potato measured the highest amount of volts. I tested three more; banana, apple, and tomato and found the
banana was comparable to the potato in voltage. From my research, I found that potatoes and bananas were very
high in manganese, magnesium, and potassium and that potassium and magnesium are good electrical conductors.

Title: The Effects of Dimples on Golf Balls
Abstract: Reserach shows that dimples on a golf ball help to increase lift and reduce drag, resulting in longer
distances. For my project, I used three different Titleist golf balls to see if the ball with the most dimples would fly the
farthest. I created a golf machine out of wood that would hit a golf ball consistently with the greatest distance of 14
meters. The results showed that the ProV1 golf ball went the farthest even though the DT Solo had the most
dimples. If the swing speed was higher at impact, greater distances might have provided different results.

different temperatures than less expensive golf balls. I hypothesized that as the temperature increases the more
expensive golf balls will bounce higher. I dropped 3 golf balls of 4 different brands at 4 different temperatures. I am
still collecting data so if you wish to see my results, I will have it available on the day of the fair.

was measures over a 45 minute period of time. The temperature of the cooling water was recorded at regular
intervals of five seconds. I also used a different starting temperature for the water being tested in each experiment.
After the data from the tests was collected, I had to extend the data so that, instead of the tests having above-
freezing ending temperatures, they would end at the freezing point. In the end, I saw hotter water actually froze
faster than colder water. Hotter water did freeze faster than colder water.

Title: Best Insulating Layer of Fabric
Abstract: The purpose was to find the best insulating, cold weather fabric, testing sheepskin, fleece, fake-fur, and
wool. It was hypothesized that sheepskin insulates best due to its thickness, allowing it to trap more heat. Five test
tubes were filled with 37 degrees Celsius water and covered with sewn-fabric tubes, inner moisture-wicking, middle
insulating, and outer weather-resistant layers. The control had no middle layer. Temperature was measured regularly
for 45 minutes and three trials. Ultimately, the experiment supported the hypothesis that sheepskin would insulate
best. Results were inconclusive because a synthetic fabric, insulated second best. This experiment benefits future
generations who will need to search for recyclable/recycled materials.

Callaway, Srixon, Taylormade, and Titleist, and with ionomer covers were Nike, Noodle, Slazenger, Top-Flite, and
Wilson. The results showed that my hypothesis, Taylormade and Slazenger golf balls would bounce higher than the
others, was proven correct, thus equaling greater distance.

solar light was positioned on a rotating disk and exposed to the light for 50 minutes every 20 degrees (Non-fixed). I
hypothesized that the non-fixed solar panels would capture twice the amount of power than fixed. The results
supported my hypothesis since the tracking group consistently produced a longer charge.

Title: Temperature on Solar Cells
Abstract: Solar cells are devices that turn energy from the sun into power. Many researchers have shown that heat
can negatively affect the power output of a solar cell. I tested this theory by putting the solar cell under a high power
lamp and recording the voltage output of it for every 2.8 degrees it rose until it reached 60 degrees Celsius. I did this
9 times, three times at room temperature, in the refrigerator, and in the freezer. I discovered that the solar cell
performed best in cold temperatures due to the fact that the flow of electrons is resisted by the heat of high
temperatures. In conclusion, solar cells would be best suited for cold, clear climates.

Title: Turn That Down!
Abstract: The effectiveness of different types of earplugs for reducing machine-generated noise was explored in this
experiment. Each year, there are nearly 1 million people that are exposed to loud sound levels from machine noise
that can cause hearing damage. First, decibel level readings were taken and averaged without the earplugs as a
control group. Eight types of earplugs were tested 3 times each (27 trials in all) using a simulated head, engine noise
file (played at a controlled decibel level each time), and a decibel meter placed inside the simulated head to record
decibel levels. The noise reduction rates (NRR) of the foam earplugs were much lower than the NRR of the silicone
earplugs. In conclusion, the silicone earplugs performed the best because they conformed to the shape of the ear
canal to block more noise.

Title: Effects of Temperature and Elasticity
Abstract: "How does the elasticity of a rubber band change with temperature when submerged in water?" The
purpose is to investigate how the flexibility of a rubber band varies with temperature in water. After gathering all
materials, fill a beaker with boiling water and submerge a weight, tied to a rubber band. Then measure how far it
stretched in five-minute intervals. Repeat this twice. As temperature decreased, it became more flexible. When it
reached around 25 Celsius, it stopped. In all three tests, it stretched 0.4 centimeter. By doing this experiment, I've
learned temperature doesn't have a big effect on elasticity.

Abstract: The purpose of this experiment is to test the buoyancy of eggs. My hypothesis was that I would need at
least 40 mL of salt in the cold water. For the warm water, I think I will need 20 mL or less of salt. I tested 5 eggs in
each temperature of water. Once I saw that the egg floated, I recorded the amount of salt that I had added. My
hypothesis was incorrect. Both temperatures took much less salt than I expected to make the egg float. In addition,
the cold water took less salt than the warm water.

frequency changed underwater. By connecting to certain software, I was able to record the frequency of a sound in
normal and salt water. My results showed that frequency increases almost four times in salt water. Sonar is a very
high-pitched noise in general, so it likely did create fatal injuries among the whales.

Title: Let There Be Light
Abstract: For my project, I have chosen “Will a parallel or a series circuit make a light bulb brighter?”. I have learned
how to make a parallel and a series circuit and why each one is as bright as it is. The purpose of this experiment was
to see if a light bulb was brighter wired in parallel or in series. For series circuit, you connect a wire from the clip, to
the negative side of one battery. Then you run a wire from the positive side of that battery to the switch. And finally,
you run a wire from the switch, back to the light bulb. For a parallel circuit, first you run a wire from the positive side of
one battery to the negative of the other. Then you run a wire from the other positive to the light bulb. After that, you
run a wire from the light bulb to the negative side of the other battery. And finally from the negative side to the light
bulb and from the light bulb back to the positive. The results of this experiment were that the parallel circuit was
brighter because each light bulb had one wire going to its own battery so each got 3.0 volts. But in the series circuit,
the light bulbs only had one wire, so they had to split the volts; therefore each light bulb got 1.5 volts. In conclusion,
this project did agree with my hypothesis: The parallel circuit would be brighter than the series circuit.

Title: Tennis Ball Mortar
Abstract: Due to unforeseen weather conditions, I was not able to fire the mortar in the time allotted. I will continue
to test the mortar and this data will be available at the fair. However, I was able to find a simulator online which
calculates distance and trajectory. I experimented with this site and found that a 10° firing angle is the best to reach
my goal of 100 meters. My hypothesis, which was that a 10° angle would fire a tennis ball 100 meters, was correct
using the simulator, but I will continue to test to refine my conclusion. Again, conclusive information is not available at
this time but will be at the science fair.

Title: (Don't) Go With the Flow
Abstract: We created a test method for measuring the efficiency of five different types of materials in homemade
tight weaved burlap bags to see what materials worked best to stop flood waters. We hoped to determine if there
was an easier to use media that would make the bags lighter for the emergency workers, be lower cost, and more
effectively stop the flood waters. Our results proved that there were more efficient materials for packing in flood
control bags that stop water better and weigh less. This positive outcome could affect future emergency plans and

Abstract: Our experiment tests if hamsters can be trained to go through a certain color maze. Red, blue, and yellow
construction paper will be used. Since the hamsters are color blind we are seeing if they can see shades of gray. We
decided that the color they needed to know was blue. After they went through the blue one we gave them a raisin.
Then we are we are going to put the mazes together and see if they go through the blue. We don’t think they will
figure it out.

Abstract: My hypothesis is the candle will burn underwater. The purpose of our project was to see if a candle could
burn underwater. We tried this by experimenting with different candles and different amounts of water. First we filled
bowls with amounts of water. Then we lit the candles and put them in the water. Then we put a jar over one of the
candles and it burned for a few seconds and sucked up the water. We found out that it worked as long as the flame
didn’t touch the water. The jar filled with water as the candle burnt.

Abstract: In our experiment we are trying to find a less polluting way to create the most energy by using
a wind turbine. Our hypothesis was that the larger the blades, the more energy would be produced. We tested this
experiment by using four different blade sizes. In the end results showed that the 9 cm blades worked the best, but
the 12 cm blades produced the second least amount of energy. Our hypothesis was partially true.

Abstract: Medications help us feel better when we are sick, but they can be dangerous when not used right. Every
year, many children become ill and even die from accidental poisoning by taking medications meant for adults. The
invention of childproof containers helped to greatly decrease these unfortunrate events. But are childproof containers
really childproof? In this experiment, the effectiveness of childproof containers will be put to the test by a small group
of five year old kindergarteners. They will be given a set time limit to open containers with different lids. Will they be
able to do it?

Title: Does Caffeine Make You Nervous?
Abstract: The purpose of this experiment is to determine if caffeine helps or hinders hand/eye precision. Methods
included ten human subjects, (5 boys and 5 girls) drinking a 354.88ml can of Mountain Dew, waiting 15 minutes, and
then repeating the “hand/eye game”. The experimental results were measured by observing how efficiently the
subjects performed the task. The median, mode, and mean were calculated. The results of the experiment are that
the test subjects performed the “hand/eye game” better after caffeine. The results indicate that the hypothesis should
be rejected because the test subjects performed the “hand/eye game” better after caffeine.

Title: Does Color Affect What Birds Eat?
Abstract: The purpose of the experiment was to study if birds use sight regularly when they are feeding. The first
step in our project was to buy the bird seed, feeders and dye. Next we dyed the bird seed by mixing the dye and bird
seed with a wooden spoon. We didn’t use much water when mixing the dye and seed. We then set up the three bird
feeders close to each other at three different locations. After that we recorded how much food was lost for five days.
Finally, we got together and made our conclusions. In conclusion, it is clear that the color of bird seed affects how
much of it they eat. At the two houses that got conclusive data, the birds chose natural over both red and green. At
house A, the difference between how much food was eaten at the feeders was great. The natural birdseed got a lot
more eaten than the other colors. At house B, the natural bird seed still got eaten the most, but it was a lot closer.
The difference was only around 1.5 cm compared to 15 cm at house A. As you can see, the color of birdseed does
affect how much of it they eat.

Abstract: The purpose of this experiment is to discover how diminishing oxygen affects the appearance of a flame.
 To conduct this experiment, we put a candle into a hurricane vase. We then placed a glass cutting-board overtop of
the vase to diminish the oxygen. The experiment results were measured by gathering data, then putting data into a
logbook. The results of the experiment were: when you place something over a flame, it will slowly put out the flame
by lack of oxygen. The results indicate that the hypothesis should be accepted.

Abstract: Our project serves the purpose of modeling the knee to find how the angles of the knee affect the strain on
the patella tendon. We’ve decided to do this project because we wanted, as athletes, to understand why our knees
hurt so much. Our hypothesis of our project was that as the angle increased the stain would decrease. This therefore
states that as the knee bends more and more, the strain of the patella tendon would increase more and more. We
hope that this project can conclude solid evidence that can help many researches for knee-problems in the future.

didn’t give us the chance to explain. We burned chips in the metal bin to test how long each chip burned using the
stop watch. We knew that the longer the chip burned meant the more grease the chip contained. By continuing this
with five different brands of chips we were able to time each brand five times.

Abstract: The purpose of our project is to determine whether algae thrive better in natural lake water, tap water, or
in Alga-grow freshwater medium and at what pH level. To conduct this experiment we poured 25 milliliters of alga-
grow and 5 milliliters of Euglena into container A. In containers B and C (both at a pH level of 10), we placed 25
milliliters of Lake Erie (in container C) and 25 milliliters of tap water (in container B). Experimental results were
measured by gathering the data, placing it into our log book, and then placing the information into charts.
The results of the experiment show that our hypothesis should be rejected. The algae thrived better in high acidity
levels in all containers; the algae adapted to its environment and made it more acidic.

stabilizer would fly the farthest. We used four gliders with different sized stabilizers. We created a launcher similar to
a sling shot to launch the gliders. We timed each launch and measured how far each glider flew for six weeks. We
found out the glider with the smallest stabilizer flew the farthest overall each week. Our week results were not what
we expected.

Abstract: Baseball is the true American sport. In this experiment we tried to change the experience of this sport by
trying to alter a baseball from the inside. We believed that by doing this we could create a beter or more perfect
baseball. We used eight different kinds of baseballs four of them were altered on the inside and the rest were indoor,
regular, batting, or practice balls. Then we created a catapult to fling the balls and we also dropped the balls off of a
ladder to see how high they would bounce. the results to these tests were that the balls flew about 22 feet and
bounced from 17 to 21 inches high. Although we figured out that the regular baseball is already the best we still had
fun and learned about the wonderful game and what they use to play it.

color and fluoresce, using a black light, every 24 hours. We recorded our results. We repeated the procedure with
59 ml water. Our hypotheses were not exactly correct. We discovered the green highlighter worked the best for our

Title: What's the Size of Your Fizzle?
Abstract: We conducted an experiment where we had to drop an Alka-seltzer tablet in three different sizes into
water and time it to see how long it takes each size to dissolve. We tested three different sizes of tablets, full, halves,
and quarters. The surprise was that one of the shortest results was by a full tablet, but they also had the longest time.
The halves were about 10 seconds shorter than the average time for the whole tablet. The quarters had many of the
shortest times which we had expected.

Title: Wood Flammability
Abstract: Our project is about the following. Our experiment is about what is better to protect wood for fire, paint or
stain. We used dial rods for the wood. We painted and stained the dial rods. For the control we used plain dial rods.
We used a blowtorch to light the wood on fire. Then when the wood was on fire we timed have long the flames lasted.
We found the paint burns the longest and the control the plain wood burned the least amount of time. That means for
fire protection do not paint or stain your wood.

Title: You Grew What in Water?
Abstract: The purpose of this experiment was to find out which type of water will affect the root growth of a
hydroponically grown bean plant. To conduct this experiment we gathered three different types of water, placed a
bean seed in each cup of water, and observed. The experimental results were measured by measuring each plants
roots daily. The results of the experiment were that the tap water grew the roots of a hydroponically grown bean plant
the longest. The results indicate that our hypothesis should be rejected because our results show that the tap water
grew the roots the longest.

Title: Going Natural?
Abstract: The purpose is to help people know whether pharmaceutical antibiotics or natural remedies work better to
kill bacteria. The hypothesis was that pharmaceutical antibiotics would work better because they are more widely
used and are clinically proven. First, the materials were collected. Then, the experiment was begun following these
steps. It started by rehydrating the bacteria. The petri dishes were then labeled and the agar prepared by melting it in
a hot water bath and pouring it into the Petri dishes. The natural remedy discs were prepared by dabbing a blank
disc with Oil of Oregano. This was repeated with Tea Tree Oil. Next, 15 dishes were inoculated with Staphylococcus
Epidermidis. The dried discs were placed in the center of each Petri dish and covered with lids. This was repeated
with the pharmaceutical antibiotics. Then, the Petri dishes were placed under the heat lamp to let the bacteria grow

for one day. The following day the first observations were taken. The measurements were made by taking a metric
ruler and measuring the diameter of the zone of inhibition of all the Petri dishes; left side, right side, and across. The
data was then recorded and pictures taken. This continued for 5 days. The final data was recorded and an average
was taken. The results showed that the hypothesis was incorrect. The natural remedies killed more bacteria than the
pharmaceutical antibiotics. Out of the two natural remedies, Oil of Oregano prevented and killed the most bacteria.

Title: Ice Ice Baby
Abstract: The purpose of the experiment is to make sure people know of the possibility of bacteria in restaurants’ ice
chutes. The hypothesis stated that because fast food restaurant ice machines are used more often by consumers,
than the constant flushing of ice will make it cleaner than a rarely used home ice machine. The procedure consists of
going to the restaurants and discreetly swabbing the ice chutes, and then rubbing the swabs in a Petri dish with agar.
The dishes are placed under a heat lamp for 3 days within the temperature span of 37°C (or about 98.6°F). After the
bacteria are left to grow for 3 days, it is observed under a microscope and the data was recorded. The results showed
that restaurant 1A had the most bacterial growth, which was opposite of the hypothesis. If this project over again,
different restaurants would be tested and the bacteria would be given a longer time to grow.
