Teeth vs liquids
Class 3 placed hard-boiled eggs into different liquids and left them for 24 hours to see what would happen. We used eggs as the shell is similar to tooth enamel. Everyone was so interested, and sometimes a bit disgusted, by the changes that had taken place when we took the eggs out. Class 3 were brilliant at drawing conclusions about what the changes mean about oral hygiene and making healthy choices with our drinks.
