Adaptive teaching
Pupils needing extra support
Could use cones set out by an adult to mark every 5 m from the tablet making a sound so they do not need to use a tape measure for the investigation; could use the Resource: Variables (support) to choose which variables to measure and keep the same.
Pupils working at greater depth
Should calculate the change in decibels every 5 metres using the extension column on the data table; should apply this pattern to calculate the answer to slide 3 of the Presentation: Which will be the loudest?; could choose an extension activity relating to volume from the Resource: Stretch and challenge: Sound and vibrations.
