In our unit of personal hygiene, we touched on the importance of brushing your teeth. I thought I would include a science experiment to show how important it is to brush your teeth every day, twice a day!
I soaked hard-boiled eggs in pop over night, so in the morning they were stained brown. Working in small groups, students came over for brief discussion and questioning period. Then they were given an egg, toothbrush, and a little bit of toothpaste to see what would happen.
