Some foods and drinks damage our teeth
This Pacific class planned and carried a fair test in order to check how different liquids affect our teeth. They used eggs because the egg shell is made out of similar material as our teeth. We kept the eggs in water, Coca-Cola and vinegar for 4 days. On Thursday we checked if our predictions were correct. This smelly investigation was a part of this week's oral hygiene theme.
