Blackfell Primary School

In our PSHE session this week, we set up an experiment with egg shells. We discussed how egg shells are similar to our teeth, in each glass with an egg shell we placed one with a fizzy drink, one with a juice and another with water. We talked about what we think might happen to the eggs shells over the coming days and how this relates to our teeth. After a few days, we looked back at the egg shells, we found that the one in the sugary drink, coke, had changed colour and did not feel as hard as it used too. We saw the shell in water was in the best condition and had not changed at all. We talked about the best options for drinks and foods for our teeth and spoke about good dental hygiene.
