Brush Your Teeth! (another experiment)

P1150877brush-teeth-experimentA couple of weeks ago I saw some cute preschool activities about dental health at 2 Teaching Mommies, I was inspired!  We didn’t get to Amber’s ideas, but we did fit in the science activities from 1st grade with Miss Snowden. After talking about the germs in our house (see this post), it seemed fitting to talk about the germs in our mouths.

I hard-boiled six white eggs and we chose soda, grape juice and coffee for our science experiment.  We poured the liquid into six glass cups and let them sit for about eight hours.

At the end of the day it was time to check out our “teeth.” I had the kids predict whether their “teeth could be cleaned and which liquid would leave the most lasting stains on their “teeth.” Then the kids scrubbed away. They had a blast and worked hard at it for nearly a half-hour.

In the end, they were able to get much of the stain off, but not all of it.  And, as it was the end of the day, they headed off to brush and floss their own teeth!

Above are the “coffee” and “soda” stained “teeth.” The grape juice looked the worst initially, but became surprisingly clean.
