KS3 Activate Sound knowledge organiser

This is a knowledge organiser which contains the fundamental principles from the ‘Sound’ topic from KS3 Activate 1.
This would be suitable for a KS3 Physics class studying sound from any curriculum.
I used this to support my year 7 class with writing their own flashcards as end of unit revision, but it could have many applications.
It is designed to be visual with diagrams to support the text and key vocabulary in bold.
This knowledge organiser contains a brief overview of the following areas:

• Features of waves (amplitude, wavelength, peak, trough)
• Longitudinal vs transverse waves
• Sound (how sound travels)
• Volume and pitch (frequency and amplitude)
• The ear
• Echoes and ultrasound
• Superposition
