My sister did a project about cavities. She brought in candy and had people eat the candy and then use a pH strip to test the acidity levels in their mouth - higher acidity = higher incidence of cavities. My sister was artistic and made a model of the mouth - teeth and all (with cheap clay) - it can also be drawn or copied from various sources.
Another project would be cave formation - you can show the formation of stalactites and stalagmites (top and bottom of caves) by making rock candy. Hot water + lots of sugar. Allow to cool - use thread or string hanging from a pencil in a glass.
Just 2 suggections - very inexpensive.
I am a biology and chemistry teacher at a high school - I have tons of ideas but I am not sure how much money you want to spend or how much work / research is expected. Contact me for more info if you would like it.

Well, when I was in gradeschool (actually I was in highschool), I did a science project on burping, the effects on burping, what causes the burping, and so on. Well, I did a pretty good job. I did receive a B+ on it. You can go to your library near you and get some books on that topic.
