Pupils needing extra support

Could watch the Pupil video: Investigating friction method to help them follow the method; could mark where their car stopped with chalk and make comparisons instead of measuring and recording distance.

Pupils working at greater depth

Should gather repeat data; could discuss why is it useful to do the test more than once (so that you can spot results that are wrong) and if any of their results were wrong (no, the results for each material were very similar or yes, one of the results was very different from the rest); should complete the Activity: Hiking boot design (extension) and apply their learning to design an effective hiking boot; could choose an extension activity relating to friction from the Resource: Stretch and challenge: Forces and magnets.
