As part of our ‘Animals and Humans’ science topic, this week we are learning about our teeth. The children are now teeth experts and know the names of each type of tooth as well as what their “job” is. We then spent some time talking about how important it is to brush our teeth and why we need to do it every day. We found out what happens to our teeth if they don’t get cleaned – the build up of plaque reacts with the sugars in food to create an acid that attacks the teeth! We started an experiment this afternoon using hard boiled eggs to act as the teeth – each egg has been placed in a different liquid to see what effect it has (coke, orange juice, vinegar and milk). The eggs will be left in the liquid over night to see what happens to the shell. The children’s predictions were very interesting and tomorrow we will see if they are correct! They also made posters encouraging and promoting tooth brushing! What a busy afternoon!
