Over the last couple of weeks, in science, the children have been learning about how to keep teeth healthy! We have discussed how certain types of food can lead to cavities and to support the children's understanding we have set up an investigation using eggs. The shell of an egg is made from a similar substance as enamel, and we are looking forward to seeing if there are any changes in the eggs' shell which have been put into jars of water, vinegar, coca-cola and coffee! What do you think will happen?
