Observe - Shadows from the Sun

Making shadows requires a light source and an opaque or translucent object. Because the Sun is a light source in the sky all day, it is making shadows all day long. As the Sun moves across the sky, from sunrise to sunset, the shadows that it makes change.

Probably, you have some idea of how these shadows might change based on your own daily observations and what you have already learned about light and shadows.
