You have a shadow because your body blocks the sunlight!

Pip’s answer

  1. You have a shadow because your body blocks the sunlight!
  2. Light travels in straight lines, so it can't bend around you.
  3. The dark spot behind you, where light can't reach, is your shadow buddy!
  4. Wow-ee, when the sun sits low, your shadow grows super long!

Try it together

Can you wave at your shadow, buddy?

For grown-ups

Light travels in straight lines. When your body blocks light from a source like the sun, the area behind you receives less light, forming a shadow. Shadows are longest in the morning and evening when the sun is low, and shortest around midday.

Ask your child: Shall we trace your shadow with chalk in the morning and afternoon?
