Video notes that students can do to keep them engaged in the Study Jams video for Light: Absorption, Reflection, and Refraction. The video is only a few minutes long, but does a great job of explaining each of the Light vocabulary words. It is ideal for 5th grade but can definitely be used by other grades. If you have a few computer you can use this as a science center. Students will be able to complete sheet on their own. Also includes a formative assessment on the bottom where it asks students to draw a picture to describe each word.
I used this as a review of Texas TEK 5.6C for my 5th graders but it can be used for other grades as well.
