Tooth Egg-speriment! Prediciting

My little scientist made predictions today on a science experiment to help us learn more about the enamel on our teeth. We took three hard-boiled eggs and placed them in three separate cups filled with liquids - water, cola, and grape juice. I explained that the shell on the eggs is similar to the outside of a tooth. Students recorded their predictions. We will wait 24 hours to see what happens to our eggs.
