We are currently learning all about teeth in Year 4 so today started an exciting experiment.
In order to learn about how teeth can decay, we filled six jars with different liquids (including vinegar, water, cola, milk and orange juice). We want to see what will happen to egg shells placed inside each jar.
The results will be checked regularly and we will reveal the answer in two weeks.
Which liquid do you think will cause the most damage and why?
