Investigating effects of liquid on teeth

In Science, Year 4 have been learning all about teeth. Today, we set up our own experiment to investigate the effects different liquids have on our teeth. For the purpose of this experiment a boiled egg is going to be ‘a tooth’. We placed the boiled eggs in a plastic cup and poured a specific amount of liquid into each cup. We decided to investigate the effects of milk, water, pure orange juice, diet coke and coke.

We are going to be observing any changes over the next few days and checking to see if any of our predictions are correct
