Middle School Physical Science Teacher Guide

(PS-3852)

Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.

Measuring Light Intensity

Lab Summary

Use a light sensor to investigate how light intensity changes as it gets further from the source.

Theory

Students investigate how light intensity changes as they alter the distance between themselves and a light bulb. Students investigate light while:

  • Observing interactions of light with matter (air) by transmission and scattering
  • Learning that energy is associated with heat, light, electricity, mechanical motion, and the
    nature of a chemical

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the intensity of light
  • Using a light sensor to measure the intensity of the light at increasing distances from the light source
  • Using math skills to measure distances between a light bulb and sensor and to graph the relationship between light intensity and distance from the light
