Intended for learners transitioning from KS3 to the new GCSE science specifications (the first exams for which are due in summer 2018)
Contents: – 1x introduction for teachers – 3x lesson plans – 5x worksheets – 4x PowerPoint presentations – 1x technician notes
Objectives: Students learn about how sound reflects off various surfaces and the uses this can be put to.
Lesson 1 Students revise the properties of sound waves and think about why satellite dishes and other objects that rely on collecting waves are shaped in a certain way.
Lesson 2 Students plan a practical, using their knowledge of reflecting waves to determine the best arrangement of mirrors to make reflected light rays converge. They then apply this to determining the best shape of a sound reflector.
Lesson 3 Students use distance-speed-time calculations to work out the effectiveness of aircraft detectors that rely on sound reflection and then compare these to radar.
