Shadows don't stay the same. If you move, your shadow moves with you. You've probably also noticed that the shadow of something that doesn't move, such as a house, can move too. Have you thought about why that happens? Think about where the light is coming from that is being blocked by the house. It comes from the sun.
In this worksheet we will look at why shadows change during the day, and at how this can be a useful way of telling the time.
