Again I love science, I made some of the best projects in high school along with many other students work. I did not do it for free. The chose is yours but here is something simple.
Make a pipe organ, by cutting different lengths of 3 inch PVC pipe. From the side make it look like a "J" place it in a holder put like 14 of them together and remember the top of the "J" make different heights - now take like a piece of rubber and slap the low opening of the pipe. hit each one. hear the different, now find someone to play a small tune or you do it. I made one, it was more complex - it was awesome.

a good project would be the effect of the plate color on people's appetites. my cousin did it & he won 3rd place in the science fair for his school! i think its a really good idea, finding out what colors make our appetites increase, and what colors make our appetites... decrease. also, it's pretty easy, so you dont have to go crazy looking for information, you just need a lot of supporting data.
hope i helped :]

Try to genetically alter something, like a pea plant, to be a different color or something of the sort.
