Light is such an amazing thing! Elementary schoolers explore the wonderful world of light and shadow. The lesson is meant to be carried out on a whiteboard. Objects are placed in front of a light source, and learners must predict what will happen to the shadow on the whiteboard when the light source is moved further away from the object, then when it is dimmed. A good worksheet is embedded in the plan which can be used as an in-class or homework assignment. Very nice!
