1. Bellwork 10-28-13 Obj: SWBAT explain the properties that are used in classify minerals. 1.What comes to mind when you see this picture? 2.List as many minerals(at LEAST 2) that you can think of.(example: gemstones)

2. Bellwork 10-4-12 Obj: SWBAT explain the properties that are used in classify minerals. 1.What are the five characteristics that a mineral have? 2.What are three Id properties we talk about yesterday.

3. What is a mineral? 1. Must be naturally occurring 2. Must be a solid 3. Must have a chemical composition 4. Cannot be organic What does that mean? 5. Have a defined crystalline structure

4. How do we ID a mineral? With a partner developed some ways that you could categorize or separate different minerals?

5. How do we ID a mineral? Scientists use mineral properties to ID minerals,Some of these properties include: Color Streak Cleavage Luster Hardness

6. Mineral Color Describe the color of the mineral Azurite is blue Corundum (ruby) is red

7. Mineral Streak Describe the color of the streak on a piece of porcelain. Hematite has a RED streak

8. Mineral Cleavage Cleavage is the tendency of a mineral to cleave, or break, along flat, even surfaces. Salt has CUBIC cleavage Gypsum has ONE plane of cleavage

9. Mineral Luster Luster is used to describe how light is reflected from the surface of a mineral. Luster can be: Metallic Earthy Glassy

10. Mineral HARDNESS Hardness is a measure of the resistance of a mineral to being scratched. -It is measured on a scale from 1 to 10 -Your finger nail has a hardness of 2-2.5 -A copper penny has a hardness of 3.5 -A iron nail has a hardness of 4.5 -Glass has a hardness of 5.5 -Minerals that are harder can SCRATCH other softer minerals

11. Bellwork 11-4-13 Obj: SWBAT explain the properties that are used in classifying minerals and apply the hardness test. 1. Is Jell-O a mineral? What classifies a mineral? 2. What are the 5 properties of minerals we have taken notes on, explain each.
