Learning about Teeth!

This week in Science, we have been learning about teeth. To see how different drinks stain teeth we did an experiment with eggs, which are made out of the same minerals as teeth. We left the eggs in the drinks overnight. We observed the eggs and found that blackcurrant squash stained the most, with water staining the least. We then brushed the eggs for 1 minute and observed any changes. The brushing made the biggest difference to the squash, cola and coffee eggs.

After 1 night in the drinks.

After brushing them for one minute.

With our amazing new smiles!
