What is sound?
Sound is anything that can be heard and is a form of energy.
Why do we use sound?

What is energy?
Energy is the ability to make things move. It is needed to start the vibrations that make sound.
How is sound made?
Sound is made by the vibrations of an object. To make a sound, all or part of the object has to vibrate.
What are vibrations?
Vibrations are the back and forth movements of an object. Vibrations can be powerful, weak, fast or slow.
What are sound waves?
Sound waves are vibrations that make sound.
How do sound waves travel?
Sound waves travel away from its source in all directions.
What does sound travel through?
Sound travels through solids, liquids and gases.
How does sound travel through solids?
In solids sound travels the fastest because molecules are close together.
How does sound travel through liquids?
In liquids sound travels the second fastest because the molecules are farther apart in liquid than solids.
How does sound travel through gases?
In gases sound travels the slowest because the molecules are the farthest apart.
What is an echo?
An echo is sound waves bouncing back from a hard surface. When it bounces back it is reflected an sounds like the original sound.
What is volume and pitch?
The loudness or softness of a sound is volume. The highness of lowness of a sound is pitch.
Define amplitude.
A loud sound has a high amplitude. A low sound has a low amplitude.
How is sound measured?
Sound is measured by the number of cycles the sound wave makes in a second.
