Pupils needing extra support
Could make and test fewer structures, drawing simple conclusions; could use your demonstration piece as a visual model while they build a bridge design; could use slide 1 from the Presentation: Bridge design development to help them fill in the activity sheet.
Pupils working at greater depth
Could make and test a broader range of structures, drawing meaningful conclusions; should identify specific areas of weakness or strength; could use Activity: Bridge design development extra sheets to include their own ideas and designs if they have already made a beam, arch, laminated and corrugated bridge.
