Y4: Tooth Decay

In science we are looking at changes over time by monitoring how four different liquids affect our teeth. We are using eggs as a representative of teeth as they are quite similar in make up...ask your child why this is and see if they can remember the layers of the tooth!

We made some very interesting predictions yesterday. Which do you think will decay the tooth the quickest or slowest and why? Orange Juice, Cola, Milk or Water?
