ACTIVITY 1
PURPOSE: SUMMARY:

Observation of Physical Properties
Students will use their powers of observation, data reporting skill, and list of attributes to identify a common object. Students are given a peanut and they must write and draw their peanut. The peanut is placed in a group of peanuts and the student, using his recorded observations must find the exact peanut. One peanut, a copy of the attribute list, and one student worksheet for each student. Common Sense: Peanut allergies

EQUIPMENT: SAFETY:

ACTIVITY 2
PURPOSE:

Metric measurement
Students will demonstrate how to use metric measurement, (length, mass, temperature, and volume), and how to convert metric to English and English to metric. Students will participate in multiple activities demonstrating the different ways to measure matter using the metric system. Student worksheet, metric ruler, triple beam balance, counter-weight balance, conversion chart, graduated cylinders, thermometer with Celsius and Fahrenheit. (The tools depend on the activity the students are participating in.) Common Sense: Thermometers may contain mercury and the graduated cylinders may be made of glass and therefore create a glass hazard.

ACTIVITY 3
PURPOSE:

Graphing Lab
This activity allows students to use familiar substances to predict, record, create and interpret graphs, and draw conclusions based upon their results. Students will predict the number and colors of the M&M’s in each bag and then record the actual numbers and colors. From that information, students will create a graph, compare information with other students, and then draw conclusions based upon all of the information they received. One individually wrapped snack-size package, one data worksheet, and a set of colored pencils or crayons for each student. Common Sense

ACTIVITY 4
PURPOSE:

Acceleration and Motion
Demonstrate acceleration due to gravity with objects of different horizontal speeds falling at the same rate and to determine whether mass affects the speed at which things fall. These activities create an opportunity for students to create experiments that explain acceleration and motion. Two marbles of the same size but different colors, two larger marbles of the same size, a ruler with a groove down the middle, two books, three identical rubber balls, tape, string, student worksheet, and scissors for each group of students Common Sense: Marbles may be harmful if swallowed.

ACTIVITY 5
PURPOSE: SUMMARY: EQUIPMENT: SAFETY:

Introduction to Circuit Symbols
Students will demonstrate how to read and draw simple circuit diagrams using accepted symbols. Students will use pictures to create diagrams and then create working simple circuits based upon their diagrams. Student worksheets; circuits equipment Heat and electrical shock hazard.

ACTIVITY 6
PURPOSE: SUMMARY: EQUIPMENT:

Conductors and Insulators
Students will test objects and determine whether or not that object acts as a conductor or insulator of electricity. A simple circuit is constructed and students use this to test objects in the room to determine whether they are conductors or insulators. One student worksheet, one battery in a battery holder, three alligator clips or 3 12” copper wire (20-22 gauge), 1 amp bulb in socket, and a classroom Heat and electrical shock hazard

SAFETY:

ACTIVITY 7
PURPOSE: SUMMARY: EQUIPMENT:

Series and Parallel Circuits
Students will compare the attributes of a series circuit and parallel circuit. Students will create a series and a parallel circuit and demonstrate the benefits and pitfalls of each. One students worksheet, two or three light bulbs with sockets, three or four alligator clips or three or four 12” pieces of copper wire, (20-22 gauge), and one battery in a battery clip Heat and electrical shock hazard

SAFETY:

ACTIVITY 8
PURPOSE: SUMMARY:

Fuses and Electrical Bypass
Students will demonstrate how a fuse and an electrical bypass work in an electrical circuit. Students will create a fuse, blow the fuse, and record what happens. Then students will create an electrical bypass, experiment with the alternative routes, and record the results. One student worksheet, one battery in a battery clip, (a second may be needed for extra juice), two alligator clips or 2 12” pieces of copper wire (20-22 gauge), one bulb with a socket, one strand of Christmas tree tinsel, one pad of extra fine steel wool, one pair of tweezers, one clothespin half, tape aluminum foil, and paperclips. Heat and electrical shock hazard.

ACTIVITY 9
PURPOSE: SUMMARY: EQUIPMENT: SAFETY:

Magnetism, Positive and Negative Charges
Demonstrate the effects of positive and negative charges as well as magnetism, which is the effect of a moving charge. Students will participate in activities that show the movement of negative charges to join positive charges. One student worksheet, one rubber balloon, one piece of paper, and a pair of scissors. Common Sense: Scissors may cause serious cuts.

ACTIVITY 10
PURPOSE: SUMMARY: EQUIPMENT:

Physical vs. Chemical Changes
To identify characteristics related to physical and chemical changes. Students will participate in activities that demonstrate the differences between a physical and a chemical change. One student worksheet, one student information sheet, one balloon, one block of wood, one clear plastic cup, one ice cube, one 12” piece of string, one straw, limewater (calcium hydroxide), matches, and salt. Calcium hydroxide may cause irritation to the skin. Hazardous if swallowed. Contact a physician immediately.

SAFETY:

ACTIVITY 11
PURPOSE: SUMMARY: EQUIPMENT: SAFETY:

Fire Extinguisher
Demonstrate a chemical change Students will use this activity will be practicing science process skills to create a chemical change. One student worksheet, one beaker (1000 ml.), one candle, baking soda, pie pan, matches, and vinegar. Fire hazard

ACTIVITY 12
PURPOSE: SUMMARY: EQUIPMENT:

Mixtures and Solutions
Demonstrate characteristics related to mixtures and solutions Students will participate in three different activities that demonstrate specific characteristics of mixtures and solutions. Student worksheets, polystyrene peanuts, acetone, rubber gloves, beaker, sugar, flour, powdered drink, cornstarch, instant coffee, talcum powder, soap powder, water, plastic cups, oil, salt, cereal with raisins, tweezers, burners, triple-beam balance, graduated cylinders, sand, magnifying glasses, metal filings, magnets, clear plastic containers with lids, and Popsicle sticks or other material for stirring. Acetone is very flammable and can cause irritation to the skin, eyes, and lungs.

ACTIVITY 13
PURPOSE: SUMMARY: EQUIPMENT: SAFETY:

Acids and Bases
Determine whether substances are acids or bases Students participating in this activity will be able to identify acids and bases, using litmus paper. One student worksheet, a divided tray, litmus paper, ammonia, lemon juice, washing soda (sodium carbonate), water, and white vinegar. Ammonia can cause nosebleeds and eye irritation. It should never be mixed with bleach – that creates a toxic nerve gas.

PURPOSE: SUMMARY:

Observation of the breakdown in composition of materials and the need for recycling

Students will use their powers of observation and reasoning to conclude that there is a need for recycling. At the beginning of the school year students will collect trash, i.e., gum wrappers, Styrofoam, etc., and bury the “trash” and at the end of the year dig up the trash and observe the condition of these items, then discuss the need for recycling and conservation.
