Insolation is the amount of solar radiation received by the Earth or other planet. Because the Earth’s axis is tilted, a location on Earth receives different amounts of solar radiation at different times of the year. In this experiment, a simulated sun—a light bulb—will shine on surfaces positioned at three different angles: 30°, 60°, and 90°. Computer-interfaced Temperature Probes will be used to monitor surface temperature changes caused by radiation from the light bulb.
In this experiment, you will
Graph temperature data.
Determine the relationship between angle and temperature change.
