Thanks to all that helped Robbie with his project. Here are some photos of his poster and the teeth at the end.
The Monster drink ate some of the enamel off the tooth.
Diet Dr. Pepper tooth shrunk the most in size and
weight...and was so black.
Dr. Pepper was next.
Apple juice weighed more, we are not sure what that means. Maybe the sugar was
absorbed into the tooth?
Orange juice did nothing.
Controlled tooth stayed the same.
This was fun to do, but I am so glad to have the teeth off our counter. Now we just need to talk Robbie into letting go of the poster!
