Adaptive teaching
Pupils needing extra support
Could use slide 5 of the Presentation: Looking around corners to support construction, or a pre-built periscope as a model to work from when making their own; should use the Activity: Periscope outline to support summarising how periscopes work.
Pupils working at greater depth

- I can describe that the light comes from a source and is reflected off the two mirrors before entering our eyes.
- I can use ray diagrams to explain how a periscope works, with light travelling in straight lines between the light source/viewed object, mirrors and our eyes.
