Adaptive teaching
Pupils needing extra support
Could write the ‘easy’ question for the recap and recall activity; could use the Resource: Knowledge organiser: Science – Sound and vibrations 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).
