Presentation and Evaluation Judging Information, Do’s and Don’ts at the Fair Scientific Method The process of thinking through the possible solutions to a problem and testing each possibility to find the best solution. • Research • Problem • Hypothesis • Project Experimentation • Project Conclusion Research • The process of collecting information from students’ experiences, knowledgeable sources, and data from exploratory experiments. • Do use many references from printed sources • Do gather information from professionals – professors, media specialists, and scientists Problem • An “open-ended” scientific question to be solved • Example – “How does light affect the reproduction of bread mold on white bread? • Do limit your problem • Do choose a problem that can be solved experimentally Hypothesis • An idea about the solution to a problem based on knowledge and research • Ex. “I believe that bread mold does not need light for reproduction on white bread. I base my hypothesis on these facts: 1. Organisms with chlorophyll need light to survive. Molds do not have chlorophyll. 2. In my exploratory experiment, bread mold grew on white bread kept in a dark bread box.” Hypothesis con’t • Do state facts from past experiences or observations on which you base your hypothesis • Do write down your hypothesis before beginning the project experimentation • Don’t change your hypothesis even if experimentation does not support it. Project Experimentation • The process of testing a hypothesis using variables • The independent variable is the variable that you change • The dependent variable is the variable that is being observed, which changes in response to the independent variable • The controlled variable is not changed by the student Project Experimentation con’t • Do have only one independent variable during an experiment • Do repeat the experiment more than once to verify your results • Do have a control • Do have more than one control, with each being identical • Do organize data Project Conclusion • A summary of the results of the project experimentation and a statement of how the results relate to the hypothesis. • Don’t change your hypothesis • Don’t leave out experimental results that do not support your hypothesis • Do give possible reasons for the difference between your hypothesis and the experimental results • Do give ways that you can experiment further to find a solution Topic Research • Project Types • Three Steps to a Topic • Research a Topic • Topic Ideas Project Types • An Investigation – ex. How long does it take the heart to return to normal after exercise? • Construction of a Kit or Model – ex. A model of a solar home • Demonstration of a Scientific Principle – ex. Measuring lung capacity Three Steps to a Topic 1. Think of a topic you’re interested in. ex. People, animals, plants, rocks 2. Try to focus on one aspect of one topic. ex. People: What makes a person an adult? Animals: How can I best train my pet? Plants: How can plants best be protected from animals? Rocks: What do the different colors in rocks mean? Three Steps to a Topic con’t 3. Now use the same idea, but be more specific. Ex. People: How do third graders compare with adults? Animals: Does the length of an animal training session make a difference? Plants: Can companion planting protect beans from beetles? Rocks: How do you detect minerals in rocks? Research a Topic • Look closely at the World around you • Choose a topic from your experience • Find a topic in Science magazines • Select a topic from a book on Science fair projects or Science experiments Topic Ideas • Categories Astronomy; Biology: Zoology, Ecology, Microbiology; Earth Science: Geology – (Fossils/Archeology, Mineralogy, Rocks, Seismology, Volcanology), Meteorology, Oceanography, Paleontology; Engineering; Physical Science: Chemistry, Physics – (Electricity, Energy, Gravity, Magnetism); Mathematics Topic Ideas con’t • Great Project Ideas –How does the color of a background affect its absorption of solar insulation? On which foods does fungus grow best? How are teeth affected by fluorides and acids? Is there a relationship between phases of the moon and our weather? What kind of soil is best for water retention? Will antacids help soil polluted by acid rain? Project Research • The process of collecting information from knowledgeable sources. • How successful you are with your project will depend largely on how well you understand your topic. • Primary Research – information you collect on your own: Exploratory experiments, surveys, interviews and responses to letters/emails • Secondary Research – information/data that someone else has collected: book, magazine or periodical, newspaper, encyclopedia, software package, document from online service Project Report • The written record of your entire project from start to finish. • Title page, Table of contents, Abstract, Introduction, Experiment and Data, Conclusion, Sources, Acknowledgements Display Board • Do use computer-generated graphs • Do display photos representing the procedure and the results • Do use contrasting colors • Do limit the number of colors used • Do display models when applicable • Do attach charts neatly • Do use rubber cement or double sided tape to attach papers Display Board con’t • Don’t leave large empty spaces on the backboard • Don’t leave the table in front of the backboard empty • Don’t make the title or headings hard to read by using uneven lettering, words with letters of different colors, etc… • Don’t hand-print the letters on the backboard • Don’t make mistakes in spelling words or writing formulas Display Board con’t Questions?
