Lesson Plan: Properties of Light Science
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to explain that light travels in straight lines, describe how white light can be separated into the colors of the visible spectrum, and explain what happens during refraction.
Objectives
Students will be able to
- list the properties of light,
- explain that light travels at very high speeds in straight lines,
- describe experiments to show that light travels in straight lines,
- draw lines of light,
- explain that light travels at different speeds in different media, which leads to refraction,
- recognize that white light can be separated into the colors of the visible spectrum using a prism,
- name the colors of the visible spectrum,
- describe the effect of colored filters on white light.
Prerequisites
Students should already be familiar with
- names of sources of light,
- the fact that light is needed to see objects and that dark is the absence of light.
Exclusions
Students will not cover
- light waves,
- the term dispersion,
- how we see different colors,
- how color filters work,
- calculations involving the speed of light.
