Year 4 – The egg test!

Year 4 continued their investigation into human teeth today. We discussed the impact of certain types of food and drink on our teeth and decided an experiment was the next step. The egg test! Eggs contain calcium like our teeth so we took a hard boiled egg and placed it into different types of liquids. We controlled the experiment by make sure that every egg was the same size, the level of liquid was the same and the size of the cups were all the same. The only variable to change was the type of liquid. We then made our predictions as to what will happen to the egg. We shall find out the results on Monday morning!!
