This is for ninth grader in Physics.

Don't give me an idea to build a model of something.. for those at real schools, it has to be an experiment that tests a variable!! I'm in to photography, music, and cooking if you could fit it in my categories on interest. Thanks!

  1. BENHAM'S PATTERN DISC

    it's really cool and really simple

    type it into google

    it won me first place in my science fair

    it deals with light, and motion


  2. How about tone, frequencies and the difference between music and noise? Any scientific way to tell them apart?
