science experiment ideas?

[photon]

Does anybody have any good ideas for easy science experiments? I have a proposal due tomarrow for a science experiment. I'ts a 7th grade science class, but i've just been coming up with ideas that are way to complex and ahead of the class. I need smoething simple, yet shows good understanding of the topic. HELP!!![s(]

..What's the topic?

It can be any topic I want, but I'm looking for something in physics or chemistry.

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!
