Sam – a year 10 pupil - wants to know how good his hearing is and what the average cut off point for high frequency hearing is for a person of his age. Sam finds that he cannot hear sounds above 22,000 Hz. Work out what the average cut off point for high frequency hearing is for your class and compare it to Sam’s.
Pupils listen to tones of increasing frequencies until they can no longer hear to make some data.
They write a plan by considering how much data to collect, the apparatus needed, safety and fairness.
They collect and record the data for their own class in a results table.
They show their results in a graph, describe a trend or pattern and link their own results back to Sam's. They conclude by describing any problems they had in collecting their data.
If pupils fill in the worksheets fully they should get a high mark automatically.
