A Sound Education
How is Sound Related to Energy?
Energy is anything that can change the condition of matter, or the ability to do work.
- Change of position (movement)
- Change of state (ice melts into liquid, water evaporates into vapor, water vapor condenses and falls as rain, liquid water flows to the ocean)
Sound is a form of energy because it is an oscillation of pressure that is transmitted by waves (vibrations) through solids, liquids, gases and plasma.

Greg Vogt, EdD, demonstrates that sounds are vibrations that can be observed through the effects they have on objects.
Remember the xylophone? Greg Vogt, EdD, demonstrates how to build and play a similar instrument, called a metallophone, and explains how other metal objects can be used to investigate the properties of sound.
Did you know that sound travels through solids? Greg Vogt, EdD, explains how to make objects to demonstrate how sound travels.
