Easy science fair projects

What to expect

Easy doesn't mean a demonstration. Every project here still changes one thing, measures one thing and does it three times, which is what a judge looks for at any age. What makes them easy is that the answer is quick to see and simple to count, the things are already in the house, and a grown-up hardly needs to help.

If you're short of time, start here, print the results table and the board layout from the project's page, and you'll have the whole thing done in a weekend.

Counted from the projects on this page: 35 about how things move, 28 about water, ice and mixing, 10 about growing and weather; 37 using kitchen things, 31 using paper, tape and toys, 5 using the outdoors and some seeds. 55 are free with what most houses have, and the rest cost about $3 or about $2 or about $1. Testing takes 1 day. 12 have a step a grown-up does, marked on the page.
