Adaptive teaching

Pupils needing extra support

Could write the ‘easy’ question for the recap and recall activity; could use the Knowledge organiser to help them make their predictions.

Pupils working at greater depth

Could write the ‘impossible’ question for the recap and recall activity; should draw a table for recording the results of their investigation; should design ear protectors using the results from the experiment to help them choose materials and consider what other properties the ear protectors need (e.g. light, durable); could choose an extension activity relating to sound insulation from the Resource: Stretch and challenge: Sound and vibrations.
