Description
Sundials are the oldest way to tell time. The position of the sun changes during the day. The sun doesn't move; the Earth rotates around the sun, making it seem like the sun rises in the east and sets in the west. As the sun goes across the sky, the post in the center of the sundial casts a shadow on a circular plate. Marks on the plate tell you what time it is. It's just like reading a clock!
