Helping Students Understand Light
Many of the concepts demonstrated through the media in this module can be modeled in classroom activities that you can use with your students. Hands-on activities can foster a more complete understanding of light.
Watch this video, in which Rachel Connolly demonstrates some activities that you could use to help students grasp how light behaves and the different regions of the electromagnetic spectrum.

Take Notes
- How, if at all, did these activities in this video help you to better conceptualize properties of light?
- Describe some follow-up activities that, as Rachel suggests, would “open the door to a much larger exploration of all of the different regions of the electromagnetic spectrum.”
