When I did a dance-themed science project for school, my project went like this:
When I tap dance, I can do 64 taps in a minute using Shirly Temples, and I can do 67 taps in a minute using Paradiddles. If I added 15, how many could I do, if I added 30 how many could I do, and on and on.
I won first prize, and I made it all the way to state.
Good Luck! Your Science teacher should help you. Just tell 'em what interests you.
