Just in case you didn't know, along with everything else that February has to offer, it is also Dental Health Month. To show the students what effect different drinks have on our teeth, my class does this neat little week long experiment.
At home I boil three eggs. The first day of the experiment we record what each egg looks like and then place one in coke, one in red Kool-Aid, and one in lemonade. Each day we take the eggs out and describe what we saw on a recording sheet. On Friday, we take the eggs out of the liquids and brush one of them with a toothbrush and toothpaste.
