- Show children the measurements they have made and talk about how they could be presented to show clearly what happened. Help children to present results as a chart eg block diagram. Ask children to compare the results asking questions eg Was everyone the same distance from the sound when they stopped hearing it? Why not? Did the louder sound travel further? How do you know?

- contribute to a chart eg a block graph presenting the results
- compare measurements eg I stopped nearer to the sound than John stopped
- compare how far they were from the two sources when they stopped hearing them eg I went five metres with the loud source and two metres with the soft source
- state that they could hear the louder sound further away than the softer sound
