| In this lesson students carry out a first hand investigation in which they see that sound is a pressure wave in which air particles move backwards and forwards in the same direction as the sound propagates. The investigations are qualitative in nature rather than quantitative. | ||

P2 A student applies the processes that are used to test and validate models, theories and laws of science with particular emphasis on first-hand investigations in physics |
P12.1 Students perform first-hand investigations P12.2 … gather first-hand information |
D1.5 Students learn to describe the relationship between particle motion and the direction of energy propagation in transverse and longitudinal waves |
