The purpose of the experiment was to investigate which material would absorb the most heat then radiate for the most time. To carry out this experiment, a wooden insulated bow was built with a plank to hold the light. The plank connected to the house was needed to hold the light the plank and house were built with pine plywood. The light would heat up the material, which was a tin foil container. Then record the room temperature and the material temperature. This should be done for all materials.

After the experiment it was found that asphalt was most effective. The most was asphalt with a time of 135. The least for asphalt was 120. Asphalt lasted the longest therefore it the most effective
