Children in Y3 (both at home and in school) have been investigating the effect that different liquids have on our teeth. To do this, we used egg shells to represent the teeth and placed these in plastic cups filled with a variety of different liquids. We left the eggs to soak for a week before closely observing and comparing the egg shells! It’s safe to say we will all be thinking twice before drinking sugary drinks and will make sure that we clean our teeth regularly to protect them. Before carrying out our experiment, we considered how we could ensure that it would be a fair test and also made our own predictions about what would happen.
