‘Time is a precious thing. Never waste it.’ Willy Wonka
How long does it take to melt chocolate and what type of chocolate is the quickest to melt? Year 4 restrained themselves superbly to perform a fair test as part of our Changing States of Matter topic this week. Surrounded by an array of chocolate, oodles of sophisticated scientific measuring equipment and questions designed to make them wonder, they managed to investigate the effect of the varying percentages of chocolate solids on melting times – without eating a crumb! How impressive is that? Some of the students also got to shake the hand made of gas after combining a liquid (vinegar) and solid (baking soda). A big thank you to Mrs Green and Miss Walters, who diligently monitored our safety throughout these lessons.
