Good Afternoon,
In Science this half term, Jays are learning all about the digestive system. As part of this, we have been learning about all the different types of teeth and their functions. We have had a go working scientifically to explore the effects of our favourite drinks on our teeth.
Miss Schofield bought in some eggs and we put them into a range of liquids for 48 hours. We chose eggs because egg shells are quite similar to the enamel on our teeth, so it will make the effects clear for us to see. We used the following liquids in our experiment: water, sugar free squash, orange juice, coca cola and diet coke. We used 2 eggs for each liquid as we covered one in toothpaste before putting it into the liquid.
This is what they looked like:
There were a couple of things we found surprising. Firstly, we did not expect sugar free squash to be as bad for our teeth as it is. When Miss Schofield picked it up, the egg shell was eroding onto her hands, particularly when it hadn't been covered in toothpaste. Secondly, we noticed that the egg which was in coca cola didn't look as bad as the one which was in diet coke. However, we did notice that the shell was much more brittle as the smallest amount of pressure caused it to crack. Finally, we found that although toothpaste does protect our teeth, we need to make sure we are using it properly to maximise the impact.
Maybe you could try it with some other liquids at home? I would love to see what you find!
Have a wonderful weekend, Jazzy Jays.
