Sample Data/Results
Experiment 1: Solar Heating
The covered box has the final higher temperature. With the covered
box, the greenhouse effect occurs. Light enters the transparent cover,
but the infrared light is not re-radiated back out. The infrared light
heats the plate. Also, the cover traps the hot air inside the box,
isolating and insulating the air.
