Last week, we received a letter – or challenge should we say – from Mr Wonka himself. It turns out he is trying to make a chocolate bar that wouldn’t melt in children’s pockets. He thought the best people to test this would be children themselves.
So we set about: collecting different samples of chocolate; heating them up; observing when how long and at what temperature they melted; and then recorded our results.
During this investigation, we focused on making sure we were carrying out a fair test. We used the same amount of chocolate, the same cups etc and only changed the type of chocolate.
