Healthy Teeth- Science (September)

In class 4 we have been learning all about teeth. We have learnt about the different types of teeth in humans and animals and the importance of looking after our teeth. 
 
We designed an experiment to help us investigate the effects on sugar on our teeth. We used an egg to represent to the teeth and used 4 different liquids to put our egg into. We used orange juice, coke, milk and water. We checked on the egg each day and noted how the egg has changed colour and appearance.
