Set up together
Ask an adult to choose a safe, flat outdoor spot away from roads. Place a small, sturdy toy on a sheet of paper in sunlight. Keep the paper from blowing away without using anything sharp.
The adult stays with you. Never look directly at the Sun, even for a moment. If it is too hot, wet, or uncomfortable, save the activity for another time.
Trace, wait, compare
Draw around the toy’s shadow. The adult can write the time next to your line. Leave the toy and paper in the same place and return together later.
Use a different colour to trace the new shadow. Has its direction or length changed? Clouds might make it faint. “We could not see a clear shadow” is a useful observation too.
Take the wonder off-screen
Talk about which line is longer. You can compare with a strip of paper instead of a ruler. Your drawing records what you saw; it does not have to look like anyone else’s.
For a screen-free extension, hold your hand near a wall while an adult shines an ordinary torch. Move the light, and describe how the shadow changes. Never shine the torch into anyone’s eyes.
