"Watching Shadows Change" invites young scientists to explore how light makes shadows, and how a shadow changes when you move the object or the light.
- Where did the shadow come from — what blocked the light?
- How could you make the shadow bigger or smaller?
- What happens to a shadow when the light moves?
Quick work-a-long
Vocabulary: light, shadow, block, bigger, smaller.
Try it: Shine a flashlight on a toy against the wall. Move the toy closer to the light, then farther away — watch the shadow grow and shrink.
