Essential Understandings:
Sound is a form of energy
Sounds are produced from vibrations
Sound needs a medium to travel through
Light is a form of energy
The direction of light can be changed with a mirror
Light can be bent using lens
Objects absorb light, and we see color
A sound wave of greater intensity sounds louder
The more energy a sound has, the greater the volume
The more vibrations (waves) per second, the higher the pitch
Sound is created when waves cause molecules to vibrate through a medium (solid, liquid or gas)
In a vacuum (no air), sound cannot be made because there is no medium to travel through
The surface of different materials affects its ability to absorb, reflect and transmit sound
The speed in which an electron moves affects the color we see
