Adaptive teaching
Pupils needing extra support
Could plot the model data found on slide 2 of the Presentation: Catapult line graph; could use the Knowledge organiser to help identify examples of simple machines in the Recap and recall and answer the questions about levers from the Attention grabber.
Pupils working at greater depth
Should extrapolate the line on their graph to predict how far the marshmallow would travel with a lever of 14–16 centimetres; should estimate the missing data on the graph for levers with lengths of 1, 3, 5, 7, 9 and 11 centimetres; could choose an extension activity from the Resource: Stretch and challenge: Unbalanced forces.

Knowledge outcomes
- I can name the three things needed for a lever: effort, load and pivot.
- I can list the uses of levers, including cutting, opening and lifting or moving.
- I can explain that the farther the effort from the pivot (the longer the lever), the less effort is needed to lift the load.
