How Shadows Form
Science · Waves, Light & Sound · conceptual
Recognise that shadows are formed when light from a source is blocked by an opaque object, and find patterns in how shadow size changes
What mastery looks like
- Explain that a shadow forms because an opaque object blocks light from reaching a surface
- Describe the pattern: shadow gets larger when object moves closer to the light source
- Predict the shape and relative size of a shadow given the position of light and object
Check your understanding
Can How Shadows Form make shadow puppets and explain why the shadow gets bigger when you move the puppet closer to the torch?
