Children move an object in front of a flashlight and observe how its shadow changes in this interactive game from PEEP and the Big Wide World. As children slide the object closer to and farther away from the light until its shadow matches the size of the object’s outline on the wall, they discover that when an object is moved closer to the light source, it blocks more light and its shadow becomes larger. Children also explore how changing the position of the light changes the direction in which the shadow of the object falls.
