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.
Experiment 2: Solar Constant
