Loudness and pitch - complete lesson (KS3)

A complete lesson based on the topic of loudness and pitch. The lesson is based on the Activate 1 (2.3) SOW but can be used for others. All resources/activities are incorporated into the slides, no additional worksheets required. Planner cards (red, green and yellow) are needed for AFL at one of the learning checkpoints, and an oscilloscope would be good for the demonstration - a video is included if this is not possible. The lesson teaches the relationship between loudness and amplitude, and frequency and pitch prior to class wide AFL. The audible range is discussed and students are then redirected to the question posed within the starter. Students must then design an audible deterrent systems to protect certain animals (such as a goldfish) from predators making use of a table which gives the audible range of different species. The plenary is based on student reflection on their progress against the learning objectives, a soft toy can be thrown between students to elect who reads out their answer.
