Pupils in 2nd class enjoyed this simple experiment about insulation. To start off they put vaseline on one hand and none on the other hand. Their hands were covered with plastic gloves. Finally they immersed their hands into a bowl of iced water and were asked how their hands felt.
Pupils remarked how the hand with the vaseline coated on it did not feel as cold as the hand without. We spoke about wearing layers and warmer clothes during the winter months in order to insulate our bodies from the cold weather.
