Today, Year 4 have conducted an investigation about which liquids are most damaging to our teeth. They designed a fair test, measured the liquids and observed the results over the day. We were surprised to discover that the cola didn’t do the worst damage so far, but will wait to see the final results next week. We were also excited to explore the new microscopes which allowed us to see the damage close up. Can you identify which egg had been left in water, which in cola and which one in orange juice?
