Shadow detectives.

Make a shadow. Change it. Trap it on paper.

Ages 3–815 minIndoors & outdoors

A torch and a couple of toys are all a shadow detective needs. Children make shadows appear, move the light to see them change, invent shadow creatures, guess before they test and trace outlines like evidence. The five Shadow Detective Kit pages below turn each step into a draw-and-save activity.

Predicting, light and shadows, comparing shapes

Five little shadow activities.

Draw, type and save your work on separate activity pages.

ONE STEP AT A TIME

Let's make it happen.

  1. Make a shadow appear

    Dim the lights with a grown-up. Shine a torch at a wall, stand a toy in the beam and watch a dark shape appear behind it.

  2. Change your shadow

    Move the light closer, then further away, then to the side. Watch the shadow grow, shrink and stretch. Say what changed each time.

  3. Compare two shadows

    Stand two toys in the same light. Look at both shadows: which is rounder, longer, fuzzier? What is the same and what is different?

  4. Invent a creature

    Wiggle your fingers in the beam or lay a toy on its side. Turn the shadow into a bird, a wolf or a monster and give it a name.

  5. Predict, then check

    Before each move, guess what the shadow will do: long, short, or gone? Say your prediction out loud, then test it and compare.

  6. Trace the evidence

    Keep a toy and paper perfectly still and draw around the shadow's edge. Trace a few toys, then match shadows back to their owners.

THE LITTLE BIT OF LEARNING

What's happening here?

A shadow is the shape where something blocks the light. Moving the light and watching the shadow respond teaches children that light travels in straight lines and that predictions can be tested: guess, check and compare is exactly how scientists work.

Keep the wondering going.

  • What happens to your shadow when the light moves closer?
  • Can you make a shadow that is taller than you?
  • Why does the same toy make different shadows in the morning and the afternoon?

Make it work for you.

Keep it simple

Hold the torch while your child moves the toys, and trace their hand shadow together. Name what you see out loud: long, short, big, small, wiggly.

Take it further

Trace the same outdoor shadow in the morning and after lunch with two colours of chalk, then explain why it moved. Try a shadow puppet show with a beginning, a middle and an end.

Not quite going to plan?

If the shadow looks faint, the room is probably too bright: dim the lights or move closer to the wall. If the shadow blurs, the light is very close; move it back a little for a crisper edge.
