This post is all about the behavior of light. I use a lot of hand motions and concrete examples to teach this unit. We make up hand motions for all of the vocabulary words and practice them. We identify how light responds to objects in the classroom. Here’s a collection of resources and ideas I’ve used in the past. Happy teaching!
1. Light Hunt
Students look around the room to find examples of items (mediums) that transmit, reflect, refract, and absorb light.
With small groups, I’ve also reviewed reflection and refraction with a light hunt. I put a few items out around the room. After students visit and interact with those materials, they can add other items in the classroom.
After we go over how light behaves with each of the items, we discuss the following question: What do the items in each group have in common? This helps us identify similarities and tendencies in each group.
2. Hands-On Vocabulary Lessons
3. Concave and Convex Lenses
Let students explore the types of lenses (which they LOVE) and explain the how and why of what is occurring.
7. StudyJams Videos
The video below was particularly helpful for my students last year. Many drew the picture shown in the video in their “output” notebook entry.
