How Greenhouse Works - Light

Lab Summary

Use a light sensor to determine how light intensity or brightness depends on the angle at which the sun's light strikes the surface of the ground and how this changes throughout the day.


To understand this content, students:

  • Change the angle at which light strikes a model greenhouse and measure its intensity.
  • Control the intensity of the light by changing the transparency of the greenhouse covering material.

Sensors / Equipment Used:

PASPORT Temperature/Sound Level/Light Sensor


Allows students to conduct all three measurements simultaneously and continuously. For use with PASPORT Interfaces.

Materials Used:

Reflector lamp or desk lamp with 60-watt incandescent light bulb
Shoebox or cardboard box of comparable size 
White legal size typing paper, white butcher
paper or white bulletin board paper, 21 cm × 28 cm (8.5 in. × 11 in.) - 2 to 3 sheets
