Science: Egg investigation

Having spent the term focussing on Willy Wonka’s Chocolate factory and the fantabulous sweets he creates, we decided to take some time in 3/4 to investigate the effects different drinks have on our teeth. We used eggs to show this because the shell of the egg is very similar to the enamel on our teeth. The drinks we choose to investigate were; cola, sparkling fruit water, milk, energy drink, water and orange juice. The children found this experiment interestingly and excitingly disgusting. They found that many drinks they thought were healthy, like fruit juice and sparkling fruit water, actually contained a lot of sugar which stripped the outer layer off the eggs and left the shells feeling flimsy. Energy drink was definitely the most destructive for our teeth, leaving the egg shell crumbling and holy. The healthiest two drinks we tested were water and milk.
