Muck, Mess and Mixtures
We predicted which items would melt and which would melt the most quickly. When carrying out the investigation we used the same hob at the same temperature to ensure it would be a fair test. We also measured the items out before melting them so that we were melting the same amount each time.
Each group made detailed observations and recorded what had changed at intervals of 1 minute and whether their item had started to melt within 5 minutes.
