Picture	Core Knowledge or Concept
	Sound is a disturbance that travels through a medium as a longitudinal wave. Sound begins with a vibration. Sound waves can travel in solids, liquids and gasses.
	An echo is when sound waves reflect off of an object
	Sound waves spread out and can diffract or bend around objects.
	The loudness of a sound depends on the amplitude or energy of its wave. Intensity is the measure of the energy of a sound wave over an area. The unit of loudness is the decibel dB.
	Distance can make sounds less loud. As sound waves spread out, they have less energy per unit of area, so they sound softer.
	The pitch of a sound depends on its frequency. The unit of frequency is the Hertz or Hz. Humans can ususally hear from 20Hz to 20,000 Hz.
	The speed of sound is different in different materials. Sound generally goes slower in gasses and faster in solids. Speed can change with elasticity, density, and temperature. A sonic boom is when something goes faster than mach 1, the speed of sound.
	Doppler effect moving sound sources can make frequencies appear higher or lower by compressing or spreading out waves.
	Scientist / Engineers Robert Moog manufactured early synthesizers by creating sound modules that could generate or change sound waves.
	Technology Synthesizers are musical instruments that simulate or create the sounds of instruments by changing the shapes of sound waves.
