Amazing Ice Melting Blocks

Description
Two blocks, one made of a highly conductive material and the other of an insulating material, are used to compare the rates of ice melting. When ice cubes are placed on each block, the ice on the conductive block melts significantly faster due to its ability to transfer heat more efficiently. This experiment vividly demonstrates the concept of thermal conductivity and the rate of heat transfer between different materials.

Preparation & Instructions
Have a student volunteer hold each block and ask which is warmer and is cooler. Show that the temperature of both is room temperature. Place the O rings on each block and place ice cubes on the block. The O rings help keep the ice from sliding off.
