Year 4 have started a Science experiment this week to look at how different liquids affect the enamel in our teeth. We have used egg shells (which are made of a similar material) to test 5 different liquids. We are going to leave the liquids in the egg shells for 7 whole days to see what happens. This week we made predictions about each of the liquids. Look at the pictures to see how much the shells have changed in the first 3 days! We are very excited to see the end results next week. Why not try your own experiment at home using some different liquids and share your findings with us.
