4Getting Started Choosing a Topic Interesting to you !Something you have a question about that is related to scienceCan answer question only through an experiment
5Guidelines for choosing a topic Only THIRD graders can do consumer projectsNo Projects involving VERTEBRATESNo ModelsNo Bacteria ProjectsNo Molds Project
6CONSUMER SCIENCE IS FOR THIRD GRADE ONLY What paper towel soaks up the most water?What diaper absorbs the most liquid?Which ketchup is thicker?Consumer science is testing a product or comparing it to another brand of the same product.
18Experiment NightConduct an experiment from start to finish with your parentsGet ideas for your own project
19Things you must include in your project Display board with all parts of scientific methodJournalResearch Paper (4-6 grade)
20Display of the Science Fair Project ProceduresTitleQuestionWritten Explanation*HypothesisVariablesConclusionMaterialsData Chart*Graph** All parts of the Results.
21Research Paper Title Page Acknowledgements Question Background researchWrite down questions that you want to know about your topic that you can be answered by looking in a book.Sources/BibliographyTwo examples of research papers written by students are included in the journal.
22Science Fair Projects are due in school by April 6,2010 No LATE projects will be entered into the fair !
23Student JournalTake a look at the Table of Contents to see all of the information included in the student journal.You must maintain this journal during the entire science fair project and turn it in with the display. There will be no available replacement should you loose your journal.
24Science Fair is on April 08,2009 Each student will be interviewed and scored by a judgeStudents at each grade level will be awarded first, second and third placeKids for Science county competition for grades 4-6 winners
31What is the Purpose of a Control? Controls are NOT being testedControls are used for COMPARISON3131
32Other VariablesThe factor that is changed is known as the independent variable.The factor that is measured or observed is called the dependent variable.3232
33Example of Controls & Variables For example, suppose you want to figure out the fastest route to walk home from school. You will try several different routes and time how long it takes you to get home by each one.Since you are only interested in finding a route that is fastest for you, you will do the walking yourself.3333
34What are the Variables in Your Experiment? Varying the route is the independent variableThe time it takes is the dependent variableKeeping the same walker throughout makes the walker a control variable.3434
35One more thing… it is best to make several trials with each independent variable. 3535
37Control - A part of the experiment that is not being tested and is used for comparison. Variable - Any part of an experiment that can vary. Independent Variable - The part of the experiment that is manipulated or changed by the scientists or person performing the experiment. Dependent Variable - The part of the experiment that is affected by the independent variable.
38Krusty Krab Breath Mints 1. Which people are in the control group Krusty Krab Breath Mints 1. Which people are in the control group? The people who received the mint without the secret ingredient (Group B) would be the control group. 2. What is the independent variable? Secret ingredient in the breath mint 3. What is the dependent variable? Amount of breath odor (or bad breath) 4. What should Mr. Krabs’ conclusion be? The breath mint with the secret ingredient appears to reduce the amount of breath odor more than half the time, but it is not 100% effective. 5. What is another name for the fake breath mint that the people in Group B received?Regular breath mint 6. Why do you think 10 people in group B reported fresher breath? This may be due to the placebo effect.
39A placebo, as used in research, is an inactive substance or procedure used as a control in an experiment. The placebo effect is the measurable, observable, or felt improvement in health not attributable to an actual treatment.
40Sponge Bob Clean Pants 6. What was the problem Sponge Bob Clean Pants 6. What was the problem? SpongeBob’s pants were not clean. 7. What is the independent variable? Laundry soap 8. What is the dependent variable? Amount of dirt left on the pants (or how clean the pants were) 9. What should Sponge Bob’s conclusion be? Clean-O laundry soap does not appear to be effective in cleaning
41Squidward’s Symphony 10. What is the independent variabl? Instrument 11. What is the dependent variable? Number of jellyfish 12. What should Squidward’s conclusion be? The clarinet did seem to attract a large number of jellyfish, but the average number for the three trials also matched the average for the guitar. The flute attracted the least number of jellyfish, but the average for this category is still larger than the control. Music seems to attract jellyfish in greater numbers than when no music is played. Squidward’s hypothesis that the clarinet attracts larger numbers of jellyfish than other instruments is not proven by this experiment alone.e
4213. Are the results reliable 13. Are the results reliable? Based on the limited amount of information provided, it is difficult to tell if Squidward’s results are reliable. The description did not tell how long each break was between trials. Did he leave enough time for the jellyfish to “clear out” of the area? (NOTE: Accept other potential flaws that students can support.)
43Super Bubbles 14. What did the Super Bubble ads claim Super Bubbles 14. What did the Super Bubble ads claim? The ads claimed that the Super Bubble solution would produce bubbles that were twice as large as those made with regular bubble soap. 15. What is the independent variable? Type of bubble solution 16. What is the dependent variable? Size (diameter) of the bubble
4417. a. Calculate the average diameter for each. Super Bubble = 15 17. a. Calculate the average diameter for each. Super Bubble = 15.1 cm Regular Soap = 11.5 cm b. What should their conclusion be? The Super Bubble solution did not seem to produce bubbles that were twice as large as those made with the regular soap. Although the average for the Super Bubble solution was larger than that for the regular soap, it was not “twice as large” as the ads claimed. In fact, only two of the ten trials had results that would fit the ads claims.
4518. Are the results reliable. Why or why not 18. Are the results reliable? Why or why not? The description does not say who blew the bubbles for each solution. There may be differences in bubble sizes due to the person blowing the bubble rather than the bubble solution. They might have considered having each person blow 5 bubbles with each solution. (NOTE: Accept other potential flaws that students can support.)
46Reminders: Make sure that the students are answering the Science Problem of the Week,we need the result in the 2nd Quarter’s PMAPP Sample Answers are in Appendix of CFPG also the STEM Fair information.
