Before the lesson
- To explore the concept and features of structures and the stability of different shapes
Pupils should be taught to:
- Explore and evaluate a range of existing products
- Evaluate their ideas and products against design criteria
- Build structures, exploring how they can be made stronger, stiffer and more stable
Pupils needing extra support: The shapes could be premade and the experiment could simply be demonstrated, or alternatively put children in mixed ability pairs or groups. Utilise the word bank edition of the Activity: Baby Bear chair analysis and consider putting them in pairs. If necessary, approach the chair analysis as a class or group and where possible, use real examples of a gym ball and stool.
Pupils working at greater depth: Could work individually and make a wider range of shapes to To find out whether something works as it should or if you know something….. You could then encourage them to combine shapes or come up with their own shapes to test. They could label the diagrams in more depth, for example, where there might be visible nuts and bolts or other joints, identify materials used and why they are good choices, identify how the stability could be improved.
