One of the hardest parts of the science fair project is coming up with the idea. What are you interested in? Is there a question youve always wanted to know the answer to? Is it testable? Is it measurable? How to get ideas: 1. Look on the internet on science fair idea websites.. </li> <li> Slide 7 </li> <li> http://www.sciencebuddies.com/ Science Fair on About.com 2. Look in the science textbook. Many labs can be converted into science fair projects. a. Are You Getting Your Vitamins? (8 th grade textbook P. 324) testing beverages for Vit. C. b. Which antacid neutralizes stomach acid with the smallest number of drops? (8 th grade P. 280) c. What factors affect the speed of rotation of a lawn sprinkler? (8 th grade P. 423). </li> <li> Slide 8 </li> <li> d. How can cut flowers stay fresher for a longer period of time? (7 th grade P. 27). e. Is there a relationship between exercise and the amount of carbon dioxide you exhale? (7 th grade P. 128). 3. Go to the Santee library and check out a science fair ideas book. 4. Borrow a science fair book from Dr. Shevinsky. </li> <li> Slide 9 </li> <li> Whats Next? Once you have picked the project youre interested in its time for background research. What is the science behind your project? Use the science textbook, encyclopedia, and then, maybe, the internet. Students must use at least two print resources for their research. If you have used an idea from the textbook the background research is the chapter and section where the idea was found. </li> <li> Slide 10 </li> <li> Some good web sites: http://www.howstuffworks.com http://www.ask.com http://www.sciencebuddies.com/ For chemistry experiments: http://www.chem4kids.com </li> <li> Slide 11 </li> <li> Plan the Experiment What materials do you need? What procedure are you going to follow? a. Plan a controlled experiment with only one manipulated variable. b. There must be at least one responding variable which is measurable. c. What is the control? d. How many times will the experiment be repeated? (number of trials?) </li> <li> Slide 12 </li> <li> Does temperature affect a chemical reaction? Problem: Does changing the temperature of a solution affect the amount of carbon dioxide produced when mixing baking soda and vinegar? Hypothesis: Suggested Materials: Baking sodaIce cubes VinegarThermometer BottleMeasuring spoons Balloons Microwave </li> <li> Slide 13 </li> <li> Procedure (Suggested, can be modified) 1.Take a 1 liter bottle, add 500 ml room temperature vinegar to the bottle. 2.Add 5 ml. baking soda to a 9 balloon. 3.Put the balloon on the bottle and shake the baking soda into the vinegar. 4.After the solution stops bubbling measure the circumference of the balloon in cm. 5.Repeat steps 1-4 9X at room temperature. 6.Repeat steps 1-4 10X at 50C. 7.Repeat steps 1-4 10X at 5C. </li> <li> Slide 14 </li> <li> Perform the Experiment. At home, under adult supervision. Forms are needed for: Hazard form to use bacteria, mold, fungi, chemicals, fire anything which not handled properly can cause injury. Certificate of compliance of research involving humans for projects involving human subjects/interviewees. Forms at http://www.gsdsef.org. No experiments using vertebrate animals (can be discussed). </li> <li> Slide 15 </li> <li> Present the Experiment 1. Charts data must be quantitative (NUMBERS), units must be METRIC (cm., grams, mL, C). Temp.Circum. Of balloon </li> <li> Slide 16 </li> <li> 2. Graphs-manipulated variable on x-axis, responding variable on y-axis. Responding Variable (what was measured) Circum. Of Balloon (cm) Manipulated (what was changed) Variable (Temp.) </li> <li> Slide 17 </li> <li> Results A narrative of the data, written in complete sentences. A retelling of the numbers in the charts and graphs. For example: At 25C the average circumference of the balloon was </li> <li> Slide 18 </li> <li> Conclusion An explanation of the data. Was the hypothesis supported by the data or not? Were any problems encountered while performing the experiment? Explain the data using what was learned from the background research. For example: There was more CO 2 produced at room temperature than in the cold. Most chemical reactions work faster at warmer temperatures than cold temperatures because molecules move faster at warmer temperatures than cold temperatures. </li> <li> Slide 19 </li> <li> Works Cited At least 5 references. Listed in alphabetical order according to MLA standards. (See Science Fair Project Guide.) </li> <li> Slide 20 </li> <li> Standards for Judging 1.Creativeness originality of problem, uniqueness of approach, ingenious use of equipment and materials. 2.Scientific Thought depth of study and effort in employing scientific procedures in the solution of a clearly defined problem. 3.Thoroughness the study is complete within the scope of the problem. Scientific literature has been searched, experiments have been repeated, careful records have been kept. </li> <li> Slide 21 </li> <li> Timeline AssignmentDue Date: 1. Idea for projectOctober 27 2.
