Years 5+6, 30 children. Charlotte and Heidi’s visit this time includes…. A science experiment!!! Students were shown how to set up their own experiment which involved putting eggs in solution to simulate the effect of acid on tooth enamel. They got to put one egg in a cup with lemonade and one in water, the children could see the mineral coming out of the egg in the lemonade and the egg also went soft! All the children had a great time and learnt a lot today, a good visit.
