An engaging lesson presentation that looks at how the amplitude and frequency of a sound wave can change. The lesson uses a range of sounds from recordings and challenges the students to draw the sound waves that would have been produced. In order to understand this topic, it is essential that the key terminology is understood and can be used in the correct context. Therefore, the start of the lesson focuses on wavelength and frequency and then longitudinal and challenges the students to recognise that these could all be related to sound waves. Moving forwards, students will hear a recording and then read a music “critique” that uses the key terminology so that can link the sounds to the change in shape of the waves. The final part of the lesson involves them drawing how the different sound waves would change from the control one.
This lesson has been designed for GCSE students.
