Hmmm... seventh grade.

How about something like Newton's laws of motion?

Or maybe follow Galileo and determine the reason why a disc and a thin metal hoop roll down an inclined plane at different speeds.

Look up stuff on the internet. You are bound to find hundreds of ideas to choose from. I think in the General Physics forum someone asked the same question; maybe you'll want to check that out.

Good luck!
