Adaptive teaching
Pupils needing extra support
- Should use the Resource: Desk seesaws (support) to help them build their lever, using the picture guide to identify where the lever and pivot should be placed.
- Could use a shorter ruler or a lighter stick if they find it difficult to balance or coordinate movement, so they can still observe how the pivot changes the lever’s movement.
Pupils working at greater depth
- Should make comparisons about how the lever moves when the pivot is in different positions.
- Should begin using the vocabulary lever and pivot contextually to describe other mechanisms they notice.
