Activate 1: P1: 2.3 Loudness and Pitch

Complete lesson PowerPoint with learning outcomes, new knowledge and fun activities detailed on the slides. Student activity/worksheets are included, one of which includes an alternative to the Activate Activity, ‘Wave Diagrams’. There is a link to a video clip ‘Sound through a Medium - Shattering Glass’. Please note that you will need the following resources: an oscilloscope, signal generator, loudspeaker and microphone.

This resource is designed for pupils aiming for developing and secure outcomes. All pupils should be able to state the link between loudness and amplitude; most pupils should also be able to state the range of human hearing and describe how it differs from the range of hearing in animals; whilst some pupils should, in addition, be able to describe the link between pitch and frequency. Supporting information can be found on pages 128 and 129 of the blue Activate 1 KS3 Science Textbook.
