As part of our WAU topic, food, we looked at teeth.
We learned how many teeth we have, the names of the different teeth and the functions of particular teeth. We also learned how we should care for our teeth and what could cause tooth decay.
We did an experiment using eggs, to see the effect different liquids had on our teeth. We predicted which liquid would have the worst effect on our teeth.
We poured the liquid over the eggs and left for three days. The egg which was covered in coke was the most discoloured.
