In Science, Year 4 have been investigating the effects of different liquids on our teeth. During our experiment, we used egg shells as a representative for our teeth (as the shells contain calcium like our teeth) and placed these eggs into cups filled with different liquids. We looked at the effects of milk, milkshake, coke, sprite and water. We have had some VERY funky smells in our classroom over the past two weeks and today we finally explored these! Take a look for yourself – our faces say it all! We analysed our results looking at colour and texture and concluded that drinks with more sugar and colourings have the worst effects on your teeth.
