Worksheet for drawing lens diagrams
A simple wave machine
The Doppler Effect - students could very carefully try this at home using a mobile phone instead of a buzzer (and a tone generator such as found in the free Physics Toolbox Suite app)
Measuring the speed of sound in air (a recommended app to use with this is Phyphox and the Audio Spectrum function).
The human ear
Auditory range - you can use this video to test your auditory range at home!
An introduction to the Electromagnetic Spectrum - in addition to this video, the Nasa website also has additional pages and videos to explore each part of the electromagnetic spectrum individually.
Dispersion and rainbows
Earthquakes and seismographs - a nice introduction before leading into the topic of S & P waves. Some questions for S & P waves can be found on Isaac Physics.
Here is a video to learn about one of the careers that involve using knowledge of waves.
