Investigating tooth decay

Date: 5th Oct 2021 @ 12:09pm

How does different drink affect our teeth? Class 3 are investigating seven different drinks:

1) tea

2) coffee

3) sugar and water

4) orange juice

5) milk

6) regular coke

7) coke zero

We added egg shells to each drink because they contain calcium carbonate like our teeth. We will be observing what happens to each egg shell over a week. Look at our photos to see observations from day 1.
