Lots of fun with teeth will be shared soon...
We did an experiment on the effects of acids and sugar on the teeth using some eggs, coke, vinegar and water.
We left the eggs in the coke vinegar and water to show what happens to teeth if they are not brushed properly.
First they boiled some eggs
Then placed then into containers with coke, water and vinegar
Whilst we where waiting we talked about what we thought might happen to the eggs and they both came up with the eggs rotting away, "good guess" I thought!..
They then left the for 24 hours to see what happens and this is the result.
In order of appearance we have -
coke water and vinegar.
The Coke egg shell inevitably dissolved
The Vinegar egg had a stain left which they the tried to clean off with a toothbrush to no avail.
A good lesson was had on the importance of ensuring teeth are brushed properly every day.
We looked at the different parts of the teeth
We played some on-line games with teeth as the theme from the Colgate Website
We found some other great things to do on the homeschool share website.
Printouts and colouring pages, we also did some maths using the teeth theme.
