Grants by the National Science Foundation and the Escondido Union High School District made this project possible.
All materials absorb energy of various wavelengths.
Some absorb a great deal of heat energy and others less. The ratio of heat absorbed by an object or material to its temperature increase is called the heat capacity of that object or material. Each material will be exposed to the same intensity of light and heat radiation. Make a table in which you will record your data. Fill a small plastic cup half of water and place a thermometer in it.
