Teeth Investigation

In Science this term, we have been learning all about teeth. We have learnt the names of teeth and their uses. We carried out an investigation to find out what would happen to our teeth if we didn’t look after them. We observed the effects of different liquids on our teeth, by using boiled eggs because the egg shell is similar to the enamel on our teeth. We placed the eggs in 4 different liquids- vinegar, water, coca cola and orange juice. We studied the eggs over a period of 3 weeks. Below are pictures of the results! Can you comment with which drink caused the most damage? The children were shocked at how bad they smelt!
