Setting up the investigation
Today we investigated the question “Which liquid does the least damage to eggshells?” We learnt that the shell protects the egg a bit like the enamel on our tooth protects the living part inside.
We chose four drinks that we were going to use. We then discussed how we were going to make the test fair; by using the same amount of liquid and by keeping the eggs in the liquid for the same amount of time. We are going to observe the results over the next four days.
