Paint one metal can black and the other white. Let the paint dry completely. Fill each can with an equal amount of water and place a thermometer in each can. Position both cans under the heat lamp at the same distance where they can receive equal amounts of light.
Measure the initial temperature of the water in each metal can and record in this table. After 20 minutes, measure the temperature in each can again. Record your readings in the table.
