Do NowI want you to think about the following prompts

for two minutes.

•What was your favorite gift of the holiday season? Why was this your favorite? Did you get anything that you already have? Did you get anything that was just an upgrade of something you already have?

•What brand cell phone do you have? How often do you get a new phone? What does your phone cost? What makes your cell phone work?

Do Now (continued)Now, in your notebook, write continuously for 3

minutes about the same prompts, answering the following questions.

•What gifts did you get for Christmas / Hanukkah / Kwanzaa? What was your favorite gift of the holiday season? Why was this your favorite? Did you get anything that you already have? Did you get anything that was just an upgrade of something you already have? What did these gifts cost? What are these gifts made of? Where were they made?

•What brand cell phone do you have? How often do you get a new phone? What does your phone cost? What makes your cell phone work?

Key Concept #1What is a mineral?It is a

substance which has a

naturally occurring inorganic

definite chemical composition

What would be the opposite of this?

man-made organic random composition

Key Concept #3The Main Physical Properties

Used to Identify Minerals

Color

a poor indicator

minerals can be multiple colors

many minerals are the same color

Key Concept #3The Main Physical Properties

Used to Identify Minerals

Streak

the powder form of a mineralmore reliable than color

Key Concept #3The Main Physical Properties

Used to Identify MineralsLuster

how light reflects off a mineral

metallic non-metallic

looks like a metal

looks earthy, waxy, greasy or brilliant

Key Concept #3

Cleavage

The Main Physical Properties Used to Identify Minerals

the mineral breaks in a predictable patternbecause of its arrangement of atoms

Key Concept #3

Fracture

The Main Physical Properties Used to Identify Minerals

the mineral breaks randomly

Key Concept #3

Hardness

The Main Physical Properties Used to Identify Minerals

resistance to being scratched

It is NOT the same as breaking!

For example: You can break glass easily with steel.However, steel will not scratch glass.

Key Concept #4Minerals have a definite chemical composition.

What two elements, by mass, make up the greatestpercentage of the Earth’s crust?

siliconoxygen

Key Concept #4Minerals have a definite chemical composition.

These two elements combine to form compounds called

silicates (SiO4)

Key Concept #4Minerals have a definite chemical composition.

They combine in a specific structure called a:

silicon-oxygen tetrahedra
