Teeth
How Clean Are Our Teeth?
We had a go at brushing our teeth and then chewing a tablet to reveal the parts of our teeth that we need to clean better. Some children decided they need to clean their incisors and canines better. Others decided on their premolars and molars.
How much sugar is in our food?
The children ranked the foods from what they thought would have the most to least sugar.
Eggshell Experiment
We left eggs in a cup of water, orange juice, vinegar, coffee and coke to see what would happen to the egg shell. The egg shell represented our teeth. We found that the coke and vinegar dissolved their egg shells and the coffee stained the shell - just like our teeth!
