In our topic this half term, Year 4 have been studying our teeth, their different functions and most recently- the effect our diet has on them.

We conducted an experiment to find how various liquids we drink affect the enamel on our teeth, (did you know, that when cared for correctly, enamel- the shiny white that covers our teeth- is the strongest substance in the human body; even stronger than BONE!)

We simulated enamel with the use of the shell of an egg. We placed 4 eggs into 4 different liquids, leaving one egg in no liquid to act as a control. The liquids we chose were fresh orange juice, fizzy cola, milk and water- we used the same amount of liquid and the same size eggs in order to ensure a fair test. We will leave our eggs for four days before we check to see the effects the liquids have taken on the shells.

Some of us predict that the cola with 'rot' the shell due to the sugar, whilst other children predict that the shell of the egg in milk will become harder due to the calcium found in milk, Kyrell commented "That's because I know milk and cheese make my bones and teeth strong!" We wait with baited breath to find out the results!
