Science: Tooth enamel
Year 4 have been busy in science this week, they have been testing different liquids to see what effect they agave on tooth enamel. We were horrified to see that vinegar eroded the eggshell and caused the enamel to dissolve. Vinegar contains acids and this caused a chemical reaction. Coke also softened the eggshell and made it slimy. This is due to the high amounts of sugar in coke. We have decided the best thing to drink is water! The eggshell stayed the same, strong and hard.
