Science was very interesting this week. Year 4 set up an experiment to test how different liquids affect our teeth, except that we used eggs to represent teeth. After a 5-day soak in either water, cola, black currant juice, orange juice, sports drink or vinegar, the egg shells were examined and cleaned with a toothbrush and toothpaste. The children then observed the changes to the eggs and drew conclusions about how certain liquids may affect our teeth.
