Learning Objective: Investigate which materials are good insulators of heat. Method: Set up your boiling tubes: leave one unwrapped and wrap each of the others in a different material, using elastic bands or tape to hold the material in place. Try to make the different wrappings roughly the same thickness. Prepare lids for the containers, made out of the same material as the wrapping, if possible, otherwise made from aluminium foil or cling film. Make a hole in each lid which is just big enough for the thermometer to fit through. Use the measuring cylinder to pour 20ml of hot water into each boiling tube. Put the lids onto the containers, with a thermometer fitted through each lid so that it rests near the bottom of the water. Start the stopwatch and measure the starting temperature of the water. After 15 minutes, measure the temperature of the water in each beaker.
