This interactive activity will create an understanding of how light rays travel through different types of everyday objects(MS-PS4-2). Using full color images, students draw arrows to represent the behavior of light rays through translucent, transparent or opaque objects.
These slides can be uploaded into PowerPoint, Keynote or Google Slides and then the students create arrows on top of the images. I have included directions for finding arrows on both Google Slides and Keynote. It may take a bit of practice to move the arrows around but students do it better than us!
There are two slides for transparent, two slides for translucent and two slides for opaque that I recommend shuffling and letting them figure out which one is which and how the arrows should be drawn. I have included answer keys for each.
This activity can be used for multiple ages and can be followed with a more in depth discussion of optics for older grades. After I do this activity I have students walk around the room or do a homework assignment taking their own images and adding arrows.
