Method

Experiment Method

In this experiment, various materials are placed at equal distances from a heat source. The temperature of each material is measured before and after exposure to the heat source.

Material	Initial Temperature (°C)	Final Temperature (°C)
Black cloth	20	60
White cloth	20	30
Aluminum foil	20	25
