This week, with the year two (Oak) children at Dunkirk, we conducted an experiment in the ice and snow. It was in response to the question asked by one of the children "how does the flask keep the hot chocolate hot?"
They were really interested in the temperature of the snow too. It was –2 oC in places but 0 oC in others and the children were really interested in why (“it’s because that part is in the shade” one boy suggested). We did make sure we also had several flasks of hot chocolate ready to drink too!
Have a look here for the children's findings:
