Class 4 conducted an experiment to see which drinks would have an affect on their teeth. We used eggs as the eggs shells would act like the enamel on our teeth and put the eggs in a different liquid (coke, orange juice and water) for a week.
Here are our results:
Coke- the egg shell became stained.
Orange juice- the egg shell had been completely broken down in places and we could see and feel the egg white underneath.
Water- no change.
This showed us that water is the healthiest drink to have for our teeth.
I remember doing that. It was a great experiment.
the coke egg looks like a Easter egg and the orange looks like its mouldy and the egg in water looks normal
