Teeth!

In Science this week Year 3 have been learning about Teeth! We have looked carefully to identify the different roles of each type of tooth and most importantly, how to look after them. Having watched a rather gruesome PowerPoint about how teeth can decay, the children learnt about how they should care for their teeth.

We have also set up an experiment to investigate the effects of a variety of different types of drinks on teeth. Since egg shells, like teeth, are full of calcium we have placed eggs in beakers of Coke, Sprite, milk, orange juice and water. We are going to observe what happens to the egg shells over the next few weeks and I am preparing myself for a very smelly classroom!
