  1. Do Now 2/26 • How do you find the Hardness of a Mineral? 1-2 Mineral Can be scratched with your fingernail 2-3 Mineral can be scratched with a penny 4-5 Mineral can SCRATCH THE PENNY 6-7- Mineral can scratch glass 7-8- Mineral can scratch steel 8-9 - Mineral can scratch streak plate • Identify this mineral’s name using the ID Key: It has a non metallic luster and hardness of 4 3. Name the Four types of lusters AND an example for each: 1._ _ Example: 2._________________ Example: 3._________________ Example: 4._________________ Example: Metallic Graphite Glassy Quartz Dull Kaolinite- chalk Pearly Muscovite Mica

  2. DO NOW- Minerals 1. What is the name of this mineral? 2. What is the luster of this mineral? Galena Metallic 3. What is the name of this mineral? 4. What is the hardness of this mineral? Sulfur 2.5-3 5. What is the name of this mineral that you can write with? Graphite 6. Are minerals organic or inorganic and what does organic/inorganic mean? Inorganic- NOT made of living things

  3. DO NOW- Provide, name, type of cleavage and hardness 2 1 3 Halite 3 directions at 90° Muscovite Mica one direction 2.5 2.5 Quartz 4 directions 7 5 4 6 4 Fluorite- fracture BUT sometimes 4 directions Talc- one direction (very hard to see) 1 Calcite- 3 directions NOT 90° 3

  4. 1.What is the difference between fracture and cleavage? List 3 minerals with Cleavage: Do Now 2/27: Fracture has NO SPECIFIC shape in the way the mineral naturally breaks Cleavage does have some kind of specific shape in the way it breaks List 3 minerals with Fracture: Halite- Cubic 1. 1. 2. 2. 3. 3. Fluorite Mica- This sheets Graphite Sulfur Calcite- Rhombic 2. What DO YOU BELIEVE is the difference between rocks and mineral? Minerals have specific chemical composition and chemical structure Rocks are made up of different minerals

  5. Do Now- Name and answer question for each: Hardness? Cleavage? Hardness? Ore for? Orthoclase Feldspar, 2 directions Fluorite, 4 Talc, 1 Galena, lead hardness? Ore for? Cleavage? Ore for? Corundum, 9 Calcite, 3 directions NOT 90° Bauxite, Aluminum Hematite, iron

  6. Name these minerals! Graphite Halite Sulfur Hematite Muscovite Mica Biotite Mica Gypsum Kaolinite

  7. Do Now: What is the type of rock (Igneous, Metamorphic or Sedimentary) for the following rocks and what is the sub category? 3 1 2 Sedimentary Metamorphic Igneous Clastic Foliated Intrusive 4 5 6 Igneous Metamorphic Igneous Non foliated Extrusive Extrusive 7 Sedimentary Sedimentary 8 Clastic Organic

  8. Do Now-Sedimentary Rocks- Answer in your new Do Now Chart Made up of piece of rocks that are cemented together. • List and Describe the THREE types of Sedimentary Rocks. Then, provide an example for each TYPE of sedimentary rocks. • Clastic- • Chemical- • Organic- Example: sandstone or conglomerate Made from chemical reaction of water and a given mineral example: Limestone and geodes Made up of living material Example: coal or limestone USE the Rock KEYS to identify the Sedimentary rocks below: Clastic Organic Chemical Shale Geode Conglomerate

  9. Do Now- Metamorphic Rocks Name these rocks and state if it is foliated or non-foliated Name: Foliate or non-foliated? Marble Non Name: Foliate or nonfoliate? Schist Foliated Name: Foliate or nonfoliate? Gneiss Foliated

  10. Do Now- Igneous Rock List the name of the following rocks, type of igneous (intrusive/extrusive) and how the rocks were formed. Name: Intr/Extr: Scoria Name: Intr/Extr: Granite Extrusive Intrusive Name: Intr/Extr: Obsidian Name: Intr/Extr: Pumice Extrusive Extrusive

  11. Do Now: • What are the TWO types of Igneous Rocks? Describe and Provide an example of each. Intrusive- forms on the surface of the earth from lava or a volcano (Examples: Pumice and obsidian) Extrusive- forms from magma under the earth’s surface (Examples: granite and basalt) • What are the TWO types of Metamorphic Rocks? Describe and Provide an example of each. Foliated- layers (gneiss and schist) Non-Foliated- no layers (Marble and Quartzite) • How do Igneous rocks form? From the heating and cooling or lava and magma • How do Metamorphic rocks form? From heat and pressure deep within the earth’s crust

  12. Do Now- Names and answer the question: Orthoclase Feldspar Granite Shale Type and sub category? Common in what rock? Type and sub category? Pumice Gneiss Type and sub category? Type and sub category? Schist Type and sub category? Graphite Muscovite Mica Hardness? Marble Type of cleavage? Type and sub category? Quartz Scoria Hardness? Type and sub category? obsidian fluorite Type and sub category? Hardness? Sandstone Talc Halite Type of cleavage? Type and sub category? Hardness?

  13. Name these minerals and state something unique about each mineral: Muscovite Mica Gypsum Orthoclase Feldspar Talc Graphite Fluorite Galena Calcite Biotite Mica

  14. Do Now-Rock Review (TYPE and NAME) Igneous Sedimentary 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. granite sandstone Metamorphic Igneous gneiss Pumice Igneous Metamorphic Obsidian Marble Sedimentary Metamorphic Schist Conglomerate Sedimentary Igneous shale Scoria
