Sound from Sunflower Learning

Sound lets you show at a particle level how sound waves travel through a medium. You’ll use it to cover:
•	How areas of compression and rarefaction make sound waves
•	How changing frequency or amplitude affects sound waves
•	How the behaviour of sound waves changes in different mediums
•	How an oscilloscope can monitor a sound wave
•	How energy dissipates as a sound wave spreads out from a source
•	The relationship between simple sounds and musical notes
