Faced with this challenge question, Year 5 raced against time (and temperature) to prevent their icecube snowmen from melting away.
Children used a range of materials to test out which coat would be the best thermal insulator to prevent heat from reaching the icy interior.
After weighing the ice some children were shocked to see a sliver of ice remaining whereas others maintained their initial weight the whole way through the experiment. We now know a tinfoil coat would not trap much heat at all, whereas a few layers of plastic bags can be surprisingly effective.
Wow very creative that’s outstanding well done
