2Have a friend trace around your shadow with chalk.
3Come back a few hours later.
4Stand in the same place and then trace your shadow again. Use different color chalk.
How It Works
As the sun moves across the sky, your shadow will move too. We see a shadow when your body blocks the sunlight. The shadow position will change based on the sun’s position in the sky. Sundials, which can be used to tell time, work by casting a shadow as the sun moves across the sky. The sun follows the same pattern each day.

In this lesson, we learn that:
The sun, moon and the stars all move across the sky in a pattern.
The sun rises in one part of the sky and sets in another part.
The moon and stars also rise in one part of the sky and set in another part.
