Mrs Paglione 6th Grade Science Minerals Test
|Solid material with atoms arranged in a repeating pattern.||Define Crystal:|
| 1. Is it a solid?|
2. Is it formed in nature?
3. Is it a non-living material? (No cells allowed)!
4. Does it have a repeating crystal structure?
|What are the 4 questions you need to ask to find out if a substance is a mineral?|
|Cells||To make a substance non-living, what is not allowed?|
|Rare minerals that can be cut and polished.||Define Gem:|
|Contains enough useful material that it can be sold for a profit.||Define Ore:|
| 1. Unique crystal structure (all crystals have an orderly pattern of atoms). |
2. The way the mineral breaks.
3. Color or Streak.
5. Moh's Scale Of Hardness.
|What five properties are used to identify Minerals?|
|An orderly pattern of atoms.||What do all crystal have?|
| 1. Cleavage|
|What are the two ways Minerals break?|
|Minerals that split into pieces with smooth, regular planes that reflect light.||Define Cleavage:|
|Minerals that break into pieces with jagged, rough edges.||Define Fracture:|
|Color of powdered mineral.||Define Color or Streak:|
|How light reflects from surface.||Define Luster:|
| 1. Metallic|
|What are 4 examples of Luster:|
|Classifies Minerals from 1 (Softest) to 10 (Hardest).||Define Moh's Scale Of Hardness:|
|Talc||On the Moh's Scale Of Hardness, what Mineral is #1 (Softest)?|
|Diamond||On the Moh's Scale Of Hardness, what Mineral is #10 (Hardest)?|
|False||True or False: When doing a Streak Test, the color of the mineral powder will be the same color as the mineral.|
