Pupils needing extra support:

Should keep their toy simple, for example, using balloons instead of syringes for their pneumatic toy, using boxes with hinged lids or folded paper plates and using pre-made shapes; could be provided with an example pneumatic mechanism structure to copy before adapting into their own toy; could have the Presentation: Example pneumatic toys available during the lesson to inspire and support construction.

Pupils working at greater depth:

Should apply their knowledge of stability and linkage systems to make a more complex pneumatic toy; could create their own nets on card for the housing or additional structures.
