Why do I have a shadow?
You have a shadow because your body blocks the sunlight!

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

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?
