1. MINERALS

2. S6E5 Students will investigate the scientific view of how earth’s surface is formed.
b. Investigate the contribution of minerals to rock composition.

3. Content Objective
SW know what a mineral is, the properties to identify different minerals, and an example of a mineral

5. What is a mineral?
A naturally formed, inorganic solid that has a definite crystalline structure.

6. Examples of Minerals

7. Minerals are made of elements
An element is a substance that can’t be chemically separated or broken down into smaller substances

8. To identify a mineral: SNIFC it out!
Solid
Cannot be a liquid or a gas
Naturally Occurring
Found in nature, not man-made
Inorganic
Is not alive and never was, non-living (generally not made from Carbon)
Fixed composition
Has a chemical formula, most are formed from compounds of two or more elements, some minerals consist of one element ex. Au
Crystal Form
A definite structure in which atoms are arranged

9. Two groups of minerals
Silicate= Contains compounds of silicon & oxygen.
Nonsilicate= Does not contain silicon & oxygen.

10. Silicate or Nonsilicate?
Quartz (made of silicon and oxygen)

11. Silicate or Nonsilicate?
Fluorite (made of fluoride & calcium)

12. Mineral? Water Teeth Honey Solid Naturally Occurring Inorganic
(nonliving)
Fixed composition
