How Shadows Form
Recognise that shadows are formed when light from a source is blocked by an opaque object, and find patterns in how shadow size changes
Suggested ages 7–8
Learning journey
Your child is discovering how light behaves — learning that sunlight can be dangerous to eyes, understanding how shadows form when light is blocked, and observing how different surfaces reflect light.
Evidence of understanding
- 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
Assessment prompt
Can How Shadows Form make shadow puppets and explain why the shadow gets bigger when you move the puppet closer to the torch?
