In Science this week we were looking at what happened when you heat different materials. We heated different materials over a candle (chocolate, cheese, bread, oil, cracker and water) and saw whether they melted, burnt or stayed the same. First we had to make a prediction (this means a guess) about what we think would happen.
We also thought about how to make the investigation a fair test. Some of the ways to make it a fair test were using the same size of each material and heating for the same amount of time.
Look at the photographs above of the results of the investigation and see if you can guess what the material was before it was heated and what happened to it. Did it burn, melt or no change?
Can you remember what happened to the water?
