Year Four have been carrying out a comparative test to find out which liquids are the ‘best’ for our teeth. We used eggs to represent our teeth, as the egg shell is very similar to teeth, and we tested: water, flavoured water, Fanta, cordial, pure apple juice, pure orange juice, smoothie, milk, Pepsi max and vinegar. We left the eggs in the liquids for 48 hours. This afternoon, we made careful observations of the eggs to see the effects that the different liquids have had. We’re now going to use our results to draw conclusions to answer our question. What do think happened? Ask a Year a Four to tell you!
