Science fair ideas, please?

I'd like to do something on the negative affects of chemical preservatives in food. I'm a sophomore and I'd like something that's easy enough to do, but impressive (if that is possible?).

I also have to write a research paper proposing what I'm going to do by Monday, so if you have any sources or stuffs that'd be fantastical.
