Elementary School Science Teacher Guide

(PS-2875D)

Features 29 inquiry based labs designed for elementary students and coordinated with the standards for life, earth and physical sciences.

How Greenhouse Works - Light

Lab Summary

Use a temperature 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.

Method

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

(PS-2140)

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