Ava and I just finished our second week of 3 on a tooth unit study. I found a tooth unit from HomeSchoolShare to use as my starting point and then I am adding and subtracting as I see fit.
We started out this week by reading Science Fair Bunnies. As I looked over this book I wasn’t sure what it was going to have to do with teeth. As it turns out the bunnies do a great little experiment that we replicated at home!
This experiment is to show you what happens to your teeth when you don’t brush like you should. Not only do you get stains from the colored food, but the acid in food (represented by the vinegar) weakens the enamel in your teeth, making them more prone to cavities.
First we had to hard boil the eggs, and observe what they looked like before we put them in the containers. Note that they are very much like teeth, white in color and hard to the touch. Then we placed one egg in a container with dark soda (in the book they use orange too), and in another in vinegar.
