4. First lets look at the difference between rocks and minerals:
Earth is made of rocks
Rocks are made of minerals

8. the dozen most common minerals are called :the rock-formers.
most of Earth’s rocks are made of the same dozen minerals in different combinations.
There are over 3000 different minerals but less than a dozen are common.
L.O:SWBAT describe and identify minerals through their
physical characteristics.

9. What are minerals?
Minerals are naturally occurring substances with a definite chemical composition.
Minerals are inorganic (non-living)
Have a crystalline structure

10. Solid Substance means that it has to be. in solid form
Naturally Occuring means made by nature (PEOPLE CAN’T MAKE MINERALS!!!)
INORGANIC means it has NEVER been alive
Composition means what it is made of and how they are arranged B R E a K D O W N OF

11. 2. Why is gold considered a mineral but water is not a mineral
2. Why is gold considered a mineral but water is not a mineral? Turn and talk
Hint: look at the images below. How are gold and water different?

12. Atomic Structure
Element = 1 type of atom’ Compound = 2 or more elements bonded together Mixture = no definite proportions

13. A Mineral can be Made of …
1 element - Ex. gold, copper, sulfur, diamond
2 or more elements (compounds) - Ex. quartz, calcite, halite
Most minerals are compounds.

14. Mineral composition determines mineral characteristics
Minerals are made of one type of molecule
This will influence the form (shape) and function (use) of the mineral
Each mineral has unique structure and characteristics

15. A mineral has a chemical formula that can be written.
Ex) Calcite is CaCO3 Quartz is SiO2 Recall the difference between elements, compounds, and mixtures

16. The internal arrangement of the atoms will make the mineral have a specific shape and properties.

17. For scientists: a “crystal” is how the atoms are arranged in a mineral.
For “regular” people a “crystal” is an expensive piece of glass or a jewelry
L.O:SWBAT describe and identify minerals through their
physical characteristics.

18. Crystalline arrangement: how the atoms inside of a mineral are arranged.

19. diamonds sparkle! graphite is dull gray.
graphite is so soft, one can write with it.
diamonds are the hardest substance known to humanity.
diamonds sparkle!
L.O:SWBAT describe and identify minerals through their
physical characteristics.

20. Graphite and diamonds are both pure carbon but have different physical properties because their carbon atoms are arranged differently.
The graphite in a pencil, coal and diamonds are all made of pure carbon.
L.O:SWBAT describe and identify minerals through their
physical characteristics.

21. a mineral’s physical properties:
luster (“shininess”)
shape
hardness
cleavage or fracture (how it breaks into pieces)
streak

22. Why are rocks and minerals important to us
Why are rocks and minerals important to us? • Help us understand how the Earth was formed and continues to move. • Have many uses in our daily lives • Are a limited resource • Have important economic and environmental impacts (fossil fuels).

23. Exit ticket: answer the following:
6.What is a mineral? 7. How do minerals get their physical properties? 8. Why are the dozen most common minerals called “the rock formers”?
