This half term in Science, we are biologists.
We are learning about teeth and eating.
Last week, we conducted a comparative test to see the impact of different liquids on our teeth. We used an egg as the ‘tooth’ as egg shells are similar to teeth enamel.
We placed eggs in orange juice, Coca-Cola and vinegar. A further egg we covered in toothpaste and placed in Coca-Cola to see if it protected the egg.
We left the eggs over the weekend and observed and recorded our results when we came back to school on Monday.
We found that the Coca-Cola had discoloured the first egg but the toothpaste had protected the other egg.
The orange juice had caused the shell of the egg to start cracking and decaying!
Help at home by asking your child what could happen to their teeth if they drink sugary drinks and forget to brush their teeth!
