We thought about how we could test which drink was the best for our teeth. We used chalk because we talked about it being similar to teeth in structure. The children all gave their predictions to what was going to be the best and what would happen to the chalk.
We tested the chalk in milk, water, cola and orange juice. When we put the chalk into the cola and it fizzed some of the children that had originally thought cola would be best changed their minds.
We are going to check the results later in the week.
