 * Habitats
 * Anything than can be heard-- from a whisper, to cars on the street, to an airplane taking off is called Sound.
 * Sound is another form of energy --it is energy that can be heard.
 * All sounds are cause by objects that are moving back and forth. We call a quick back and forth motion a vibration. Anything that makes sound is vibration.
 * The two bands that help you talk are called vocal chords.
 * When a person talks, the vocal chords close.

> > > Humans Vs. Animal Hearing
 * There are three parts that make up your ear: the outer ear, middle ear, inner ear
 * The outside of your ear catches sound vibrations and directs them to the ear canal.
 * The sound travels to the ear drum, which vibrates cause little bones in the middle ear to move.
 * The vibrations of the little bones moves liquid inside the inner ear.
 * The liquid then moves tiny hairs inside the ear and send a message to the brain.
 * Most animals also have ears that work like the human ear
 * Some animals use body parts for hearing. For example the snake feels vibrations in their jaw.
 * Sometimes animals can make noise that we cannot hear because it is high or to low for the human ear.

The parts of the Ear  Properties of Sound
 * **Sound is cause by vibrations. We call each vibration a sound wave.
 * Sound waves must travel through a material to be heard. (such as air, liquid, or gas)
 * Sound travels faster through solids, medium through water, and the slowest through air.
 * Sound can be loud or soft, this depends on the size of the vibration.
 * The louder the sound is, the larger the vibrations are. (a bang on the drum, or train horn)
 * The softer the sound is, the smaller the vibrations are. (a whisper or a tiny bird)
 * Some materials can reflect some of the sound vibrations
 * Hard, smooth surfaces reflect the most sound.
 * An echo is a sound wave that is reflected back from a hard surface such as a wall or cliff.
 * Some animals locate objects by sending our sound and listening for the echo this is called echolocation. (Bats, Dolphins, and Whales use echolocation)
