For science week, Year 4 are investigating the effect that different liquids have on our teeth. To do this, we are using egg shells to represent the teeth and placing these in plastic cups filled with 6 different liquids (coke, lucozade, vinegar, water, water with sugar and blackcurrant juice.) We will then closely observe and compare the eggs at the end of the week! Before carrying out our experiment, we considered how we could make sure that it would be a fair test and also wrote down our own predictions about what would happen. Results to follow on Friday!
