Science Project Proposal Slide Show Due Tuesday morning (1/20/15) Turn in to Google Classroom, or Share on Google Docs with Mr. Temple (etemple@griffinschool.us) , or Email your slide show to Mr. Temple
Slide show should include: Title of Your Project By: Your name(s)
Question: What am I trying to find out with my project?
Hypothesis: If I do something then I think something else will happen because of what I already know about this topic.
Description of Variables Manipulated: The thing that you are deliberately changing for your experiment Controlled: The things that you will be keeping the same for all your experimental trials There should be several controlled variables Responding: The thing that you will be measuring at the end of each trial
Materials List: Supplies Tools Measuring devices Experimental subjects Etc.
Procedure: Very brief (“draft”) version of your proposed procedure Four or five steps Your final procedure should be much more detailed
Example of a Proposal Slide Show Household bacteria By Joe Student And Jimmy Sidekick
Question: Out of normal household items, which item has the most bacteria on it?
Hypothesis: If we test these households items to see which one has the most bacteria, then we think that the kitchen sponge will have the most bacteria because it is used on dishes that people eat off of and is also constantly wet.
Materials: petri dishes cotton swab labels zip lock bags agar a pan to boil water in water
Procedure: 1. label each selected item on separate petri dishes 2. Boil water and prepare the agar solution 3. Pour agar solution into the ten petri dishes 4. Create samples by touching selected household items with a cotton swab. 5. Use doorknob cotton swab by briefly touching the petri dish that label on it. Do the same for the other 9 items.
Manipulated variable: Locations swabbed for bacteria Sponge TV remote Door knob Refrigerator handle Money Shoes Computer keyboard Keys Toilet seat
Controlled variables Swabs petri dishes Agar Water Zip lock bags
Responding Variables Measuring how much bacteria each household item creates to see which one is the worst
