Adaptive teaching
Pupils needing extra support
Could have the challenges and experiments repeated or have the equipment set up before them to make it easier to repeat and follow during the Main event; could be grouped with a confident reader when completing the Activity: Exploring pneumatics and reading through the prompt questions in the Main event syringe exploration; could refer to the Knowledge organiser when summarising a pneumatic system to support spellings and examples.
Pupils working at greater depth
Could be encouraged to explore how the syringes can cause movements in further directions by considering pivots and linkages; should explain in more depth what causes the air movement at the beginning of their chosen example (input), where the air is moving and how this causes an overall movement (output).
