Lesson Plans

Light the Way:

Students will learn about some of the behaviors of light, specifically refraction, through a video, a kinesthetic activity and summarizing informational text. Students will be able explain what causes a shadow by understanding the way light travels as well as explain refraction of light. This lesson can be completed in two 40 minute time periods or over two days.

Type: Lesson Plan

How Light Moves:

Students are fascinated with light. In this lesson plan, students investigate some of the properties of how light is propagated, and using observations from simple experiments, test their predictions about the paths that light takes with different materials.

Teaching Idea

Mirror, Mirror On the Wall: Angles of Reflection:

In this activity, students are challenged to put a mirror on the wall, cover it, and find locations where they think they can see each other in the mirror. Through the activity, students find that light reflects at an equal angle as it arrives. Students then can explore a Java applet that demonstrates that the angle at which light is reflected is equal to the angle at which it arrives.

Unit/Lesson Sequence

Light Energy:

In this unit, students first explore the different forms of energy using their senses. In the next two lessons, emphasis is placed on light energy and how light interacts with other objects.
