How do shadows change throughout the day?

Shadows are created when an object blocks out some of the Sun's light. The length of a shadow depends on how low or high the Sun appears in the sky. Shadows change shape as the sun moves across the sky. The sun is low in the sky early in the morning and late in the afternoon.  At this time a shadow will be long and thin.  In the middle of the day, when the sun is high in the sky, a shadow will be short.
