How can sugary drinks affect our teeth?

In Science this half term we have been learning about our teeth and the different roles they have. We have also looked at the importance of looking after our teeth and how we can do this. As part of our learning, we decided to conduct an experiment to see which sugary drinks have the biggest affect on our teeth. To do this, we submerged eggs in 5 different liquids: squash, water, cola, diet cola and orange juice.

We made predictions about which liquid was going to be the worst for our teeth and then left them to sit in the containers for 1 week. The pictures show us investigating the changes so far.
