Eat, CHEW, Poo!
In Science, we have been carrying on with our exploration of the digestive system but focusing on how everything starts, in the mouth with our teeth. 
We carried out an experiment using eggs and different liquids to see how they affected the calcium in them. We were surprised that cola didn’t do as much damage as we thought and undiluted squash was by far the worst! We wrote about our experiments in conclusions explaining what we found out. 

We have also been learning about how to look after our teeth and created posters to share that information with others. This week we have been learning about different animals and how carnivores tend to have canines and incisors, whilst herbivores have incisors and molars. As humans are omnivores, we have incisors to cut our food, canines to tear and molars to crush.

If you want to keep on chewing, you need to look after your teeth.
