MS-PS4-1: Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
I can use models and data to explain how waves transfer energy.
Waves transfer energy, not matter.
Amplitude is related to the amount of energy a wave carries.
Wavelength and frequency describe the properties of waves.
Scientists use models and graphs to study waves.

The properties of sound waves determine what you hear as different pitches and volumes when you listen to music.
Speakers and headphones use wave properties to reproduce the sounds you want to hear.
Communication devices use waves to send information over long distances.
Doctors use waves in technologies such as ultrasound to see inside the human body.
