Outline

 * What is a Mineral?
 * A mineral is a naturally occuring, inorganic solid that ha:
 * Crystal Structure
 * Definite Chemical Composition
 * Naturally Occuring
 * Minerals are always natrually occuring
 * Inorganic
 * Minerals can't have once been alive
 * Solid
 * No gas or liquid could be a mineral
 * Crystal Structure
 * All minerals have crystals
 * Definite Chemical Composition
 * All the elements that make a mineral have to be chemically joined
 * Identifying Minerals
 * Each mineral has its own specific propeties that are used to identify it
 * Hardness
 * All minerals will have different ratings on how hard it is
 * Color
 * Streak
 * The streak can be different from the color
 * Luster
 * The luster that any mineral has depends on what is in it
 * Density
 * No matter how much there is of a mineral, it will always weight the same
 * Crystal Systems
 * Cleavage and Fracture
 * Not all minerals have cleavage
 * Special Properties
 * Some minerals have the property of flourescence, which makes it glow under ultra-violet light
 * Some minerals have electrical properties
