We were learning all about our teeth this week. We did an experiment on eggs. Egg shell is like the enamel on our teeth. We put one egg in water, one egg in vinegar and one egg in coke. We left them over night and looked at them the next day. When we brushed the one that had been left in water the shell stayed the same. When we brushed the one that had been left in coke the brown of the shell was rubbed away. When we brushed the one that had been in vinegar the shell broke. We learned that too much sugar and acid is bad for our teeth.
