On Tuesday, we carried out an investigation to find out the effects of sugary drinks on our teeth using eggs. Egg shells are made up of the same material as the enamel on our teeth – calcium carbonate. We left the eggs for 2 days to see what would happen.
Here are the results:
Water didn’t change the egg. It look exactly the same 😊
Fresh Orange Juice made a layer of the egg shell peel away 😳
Full Fat Cola made the egg shell turn brown 😰
Lucozade Energy Drink made the egg shell change colour, made a layer of the egg shell peel away and created some bubbles underneath the egg shell 😱
Milk made the egg shell get lighter 😍
In conclusion sugary drinks have a negative effect on the enamel on our teeth. We know this because the 3 sugary drinks – orange juice, cola and Lucazade – either made the egg shell peel or change colour. This shows that the same thing could happen to our teeth! Water and milk have a positive effect on our teeth. Water allowed the egg shell to stay the same meaning it would keep our teeth healthy and milk made the egg shell get lighter because it contains calcium with is really good for our teeth.
We are looking forward to carrying out our next investigation on which material is the best insulator.
