First in our egg and vinegar experiment we put the egg in a bowl and then we poured the vinegar and left it for 4 days. Then we looked at it and the shell became softer and softer and the shell floated away. In this experiment we found out that the egg shell is like a tooth. If we put acidic things on our tooth the same thing will happen to our tooth. So drink less acidic drinks and more water.

I have never thought about acidic drinks ruining your teeth as we always thought more, about sugary foods ruining your teeth! What a great way to learn about how your teeth suffer from what you eat!

What a great test to see how acids affect our teeth! What do you think would happen if I replaced the vinegar with soda pop?

Dear Miss Koo,
I think the egg is going to get sweeter because of the asid amount.
