Adaptive teaching
Pupils needing extra support
Could watch the Pupil video: Measuring shadows that is set to play on a loop to support following the method; could use the Activity: Measuring shadows results: support version to reduce written work and support drawing ray diagrams that explain the observed relationship.
Pupils working at greater depth
Should describe what affects whether a shadow appears clear or blurry at the edges; could try to explain why some shadows have blurry edges; should suggest ways of improving the method to improve the quality of results.

Knowledge outcomes
- I can recall that the light source’s position and distance can affect the shadow’s size.
- I can describe that the closer the object is to a surface, the smaller the shadow.
- I can describe that the further an object is from a surface, the larger the shadow.
- I can use ray diagrams to explain why objects that are closer to a surface have a smaller shadow.
- I can use ray diagrams to explain why the shape of a shadow is the same as the object that cast it.
