Pupils needing extra support
Could use the Knowledge organiser to help them with the definition of a force and a contact force; could act out each action for the Activity: Contact force diagrams to help them determine the force’s direction and whether the label should be push, pull or twist.
Pupils working at greater depth
Should draw their own additional force diagrams for the Activity: Contact force diagrams; should add force arrows to their own diagrams to show any opposing forces; could write their own pair of statements, one that is false and one that is true for the Wrapping up activity and swap with a partner to discuss which they agree with and which they disagree with; could choose an extension activity relating to forces from the Resource: Stretch and challenge: Forces and magnets.
