It can be a challenge to come up with a science fair project idea. There is fierce competition to come up with the coolest idea, plus you need a topic that is considered appropriate for your educational level. I've arranged science fair project ideas by topic, but you might like to take a look at ideas according to education level.

  • What percent of an orange is water?

    Get an approximate mass percent by weighing an orange or other fruit, liquefying it in a blender, and measuring the strained liquid. Note other liquids will also be present, such as oils, though in small amounts. The mass of a ml of water is 1 g. Alternatively, you could bake the weighed orange until it is dried and weigh it again.


  • Does the temperature of a soda affect how much it sprays?

    You can refrigerate a soda, warm one in a hot water bath, shake them up, measure how much liquid is sprayed out. How do you explain the results?


  • Do all brands of soda spray the same amount when you shake them up? Does it matter if it's diet or regular soda?


  • Do all brands of paper towels pick up the same amount of liquid?

    Compare single sheet of different brands. Soak a sheet until it is saturated, let the excess liquid drip off, squeeze the liquid from the wet paper towel into a measuring cup. Note you may need to use teaspoons to measure this liquid.
