Tooth Decay Experiment

Lesson: Science

Class: Year 4 Year: 2020 - 2021

We have been learning all about TEETH! We have been naming the different types of teeth in our mouth and what their purpose is. We wanted to carry out an experiment to see which liquids are good or bad for our teeth.

We did this by using eggs and different types of liquids that we (and our teachers) like to drink. We used fresh orange juice, coke, no added sugar apple and blackcurrant juice, water and tea. We left our eggs submerged in a jar with each liquid for several days and observed the change over time.

We were shocked mostly to see the impact the no added sugar apple and blackcurrant juice had on the egg! We learnt that these drinks are ok to drink within moderation and the importance of cleaning our teeth twice a day!
