1. I Can classify minerals based upon their physical properties!

2. Minerals GLE 0707.7.1 Describe the physical properties of minerals.
SPI Use a table of physical properties to classify minerals.

3. Review of Atoms and Compounds
Each element on the periodic table is made of only one type of atom. Ex.) Gold is only composed of Gold atoms, Helium is only composed of Helium atoms.
A Compound is a substance that is made of two or more elements:
Sodium + Chlorine 
Sodium Chloride (table salt)

4. What Are Minerals?
Naturally formed inorganic (nonliving) solid that has a defined crystalline structure.
How are minerals different than rocks?
Rocks are composed of minerals but minerals are not composed of rocks.

5. Common Minerals Quartz- Mica- Pyrite- Feldspar-
Realize these are just a few of the most common minerals. There are over 3800 recognized minerals!
I don’t usually recommend Wikipedia but…

6. Properties of Minerals
Crystalline Structure- all minerals will have a repeating series or pattern of atoms or molecules. The shape of a crystal is determined by the arrangement.

7. Silicate Minerals
Silicate Minerals- Contain both silicon and oxygen. Compose 90% of the Earth’s surface.
Examples- Quartz, Mica, Feldspar.

8. Non-Silicate Minerals
Very simply do not have silicon.
Native Elements are one class of Non-Silicate Minerals- Made of only one type of element.
Examples of Native Elements: Gold, Silver, Copper

10. Have You Ever Played Guess Who?
How do we identify characters in this game?

11. Physical Properties
We can identify rocks in a similar way as playing guess who:
Cleavage
Color
Hardness
Luster
Streak
Texture

12. Cleavage/Fracture
Cleavage is the tendency of a mineral to break along smooth planes parallel to zones of weak bonding. Fracture is the tendency of a mineral to break along curved surfaces without a definite shape.
Cleavage is a predictable break, Fracture is seemingly random breaking.

13. Color
Color is the most eye-catching feature of many minerals. Some minerals will always have a similar color, such as Gold, whereas some minerals, such as Quartz and Calcite, come in all colors.

15. Streak
The streak of a mineral is the color it displays in finely powdered form. The streak maybe completely different from the color of the hand specimen. One of the simplest ways of determining the streak of a mineral is to rub a specimen across a piece of unglazed porcelain known as a streak plate.

16. Texture
Characteristics related to grain size are known as a rock's texture—coarse-grained, fine-grained, and glassy are all descriptions of a rock's texture. 

17. Hardness
Hardness is measured by the resistance which a smooth surface offers to abrasion. The degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another.
