Y4 Tooth Decay Investigation

As part of our science learning about teeth, Y4 conducted an investigation to see which liquids (coke, diet coke, orange juice, milk, water) could have the most negative impact on our teeth. We used eggs as their shells are made of a similar material to our teeth, and observed changes over 48 hours. The results were quite worrying, with three of the liquids having a great impact on the shells. We’ll not spoil the final results, but the worst liquid wasn’t either of the cokes!
