Egg Shell Decay
Our egg shell investigation
Did you know that egg shells and teeth are both made of enamel? We wanted to know what can cause decay so put the egg shells in 3 different liquids; coke, water and milk and we will look at them this week to find out what has happened to them! We also put a shell in vinegar to see what happened and interestingly the outside of the shell has already started to peel off!
