Science Project Idea Brainstorm: K-2 www.tfsd.k12.id.us/pe/sciencefairguide12.pdf Which paper towel is the strongest? Which stain remover will get our grape juice better/ Which soda is most harmful/discolors your teeth? Which laundry detergent works best? What type of cup insulates the best? How could you measure the absorbency of a paper towel? Which paper towel absorbs the most liquid? How does the color of light affect the growth of a plant? What does a plant need to grow? Does a plant grow better in soil or water? How does water move through a plant? How does color of a material affect the absorption of heat? How does the water cycle work? Are all metal items pulled by a magnet? Can a magnet work through materials? What structure can with stand more weight? Does light affect how fast food spoils? What factors affect mold growth? What effect does an oil spill have on marine life? What effect does temperature have on dissolving materials in water? How do boats float? How do airplanes fly? What fruits brown the quickest when cut open? How does rust form? (over) How do rocks weather? What affect does salt have on ice? How does the fat layer under the skin of an animal keep it warm? Why to cats’ eyes look like they glow in the dark? How to icicles form? How does dew form? How can you separate a mixture? How are fossils made? What “yeast food” helps yeast create the most gas? (sugar, honey, syrup, etc.)? How does gravity affect the shape of soap bubbles? How does a pulley make work easier? Does hitting or dropping a magnet weaken its strength? How does color protect insects or other animals from their predators? How does gravity affect plant growth of pinto beans? How do newts and salamanders hear without external ears? How does gravity affect toys (slinky, paddle ball, paper airplane, yo-yo, etc.)? Does the height of the stairs affect the movement of a slinky? Does the height of an incline make an object roll further? Do all animals have the same life cycle? Does size have an effect on an object’s mass? How do temperature and/or the seasons affect plants? Have fun exploring, super scientists!!
