Sound Energy
TEKS Objective
The student will investigate the effects on an object by increasing or decreasing amounts of light, heat, and sound energy such as how the color of an object appears different in dimmer light or how heat melts butter.
Essential Understanding
The student knows that forces cause change and energy exists in many forms.
Science Background
What is Sound? National Oceanic and Atmospheric Administration (website) - Information about the basics of sound, including decibel scale, along with more in-depth concepts related to sound.

Signature Lesson
The Phenomenon of Sound, Waves: Discovery Education (website) - While rotating through six “sound centers,” students learn that sound is a form of energy that is caused by forces, travels in waves, and can pass through all forms of matter.

Ear Guitar: Exploratorium (website) - Students construct an “ear guitar” with cups and string, and hear the sound produced by string vibrations.
Assessment Ideas
Provide students with metal nails of several different lengths. Have students arrange the nails in order, from highest pitch to lowest pitch, based on the sound they produce when struck with a pencil.
