Science fair ideas please?

My friend and I are doing science fair together and we can't decide on a topic. Our teacher is a pain and it is a huge part of our grade. We want to do something that is 8th grade level but not too complicated. We both play sports and I'm a violinist and a dancer. Any ideas???

    The effects of music on athletes and why

    you could give half the people on your team ipods with music to pump them up, and the other half would not listen to music

    or the effects of classical violin music on studying

    or the effects of gasoline on fire

    Heres one:

    Try soaking a substance that dissolves (say, a Jolly rancher) in the same liquid at three different temperatures; as in sprite at 10 degrees C, 50 degrees C, and 90 degrees C

    you could record the mass of the Jolly ranchers and see what temperature dissolves the JR fastest.

    Just a suggestion.

    make sure to use a balance, and select Three jolly ranchers of the same flavor with very similar mass.

    I once did this in 8th garde. I found out what tye of insulation is the best. I used cardboard boxes and then I coated the inside with different types of insulation and put it outside to see which lost the most temperature.

    Monitor the weather and make a graph showing the temperature and humidity comparisons. Easy, all you need is a graph and a news paper every day.

    How about something involving the weird subject of balance?

    Watch this video of how to balance a fork on a toothpick, you can show other weird things that balance and explain why.
