Light and shadows

Year 3 · Lower Key Stage 2 · Y3 Light — Shadows form when light is blocked by an opaque object

Draft — awaiting teacher review

I

Concept Anchor

Light travels from a source. An opaque object blocks light, so a shadow forms behind it. Moving the object closer to the light makes the shadow bigger.

Worked example

Why is a shadow bigger when a puppet is near the torch?

  1. 1.Light spreads out from the torch.
  2. 2.Near the torch, the puppet blocks a wide part of the beam.
  3. 3.More light is blocked.
  4. 4.So the shadow on the wall is bigger.
