Activate 1: P2.2 Sound and Energy Transfer

Complete lesson PowerPoint with learning outcomes, new knowledge and fun activities detailed on the slides. Starter and activity worksheets are included, one of which includes an alternative to the Activate Activity, ‘The Speed of Sound’. There are links to video clips of ‘Sound through a medium - Flickering Candles’; ‘How to figure out how far away lightning is’; and the well-known Felix Baumgartner’s Supersonic Freefall.
This resource is designed for pupils aiming for developing and secure outcomes. All pupils should be able to name materials that sound can travel through; most pupils should also be able to describe how sound is produced and how it travels; whilst some pupils should, in addition, be able to explain why the speed of sound is different in different media. Supporting information can be found on pages 126 and 127 of the blue Activate 1 KS3 Science Textbook.
