While investigating the different states of matter (solids, liquids and gases) we decided to see how long we could keep an ice cube from melting. ICE1.jpgWe had looked at good insulators and good conductors (the frying pan experiment) and the class were set the challenge. We had a control, where the ice was just left in an open tray and we had a group who used a cool box with ice blocks. Ice3.jpgIce10.jpg
The rest of the class had to try to construct their own containers, remembering about materials which were good at insulating and would slow down the transfer of heat energy ...

In the end, the cool box and ice block combination was the set up that allowed an ice cube to last all day ...
