1 Mineral Do Nows:

2 Do Now 2/26 1. 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 Mineral can scratch streak plate 2. 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: Graphite Glassy Quartz DullKaolinite- chalk PearlyMuscovite Mica Metallic

3 1. What is the name of this very DENSE mineral? 2. What is the luster of this mineral? DO NOW- Minerals 3. What is the name of this mineral? 4. What is the hardness of this mineral? 5. What is the name of this mineral that you can write with? 6. What is the hardness of the mineral? How do you know? Galena Metallic 1- feels greasy Sulfur 2.5- chips pieces Graphite

4 Do Now: Rocks 1. List the three main types of rocks AND how they form. 1. Igneous- forms from lava or magma (melted rock above or below surface) 2. Metamorphic- formed from heat and pressure (at times appears squished) 3. Sedimentary- formed from pieces of other rocks or minerals through chemical or physical changes 2. For each type of rock (I, M, S), list and DESCRIBE the subcategories for each AND provide an example from the power point for each. A. Igneous a. Intrusive- forms from magma INSIDE the earth b. Extrusive-forms from lava on the exterior of the earth (volcanoes) B. Metamorphic a. Foliated- has crumpled lines or lanes b. Non-foliated-no crumpled layers C. Sedimentary a. Clastic- made of pieces of sand and/or pebbles of pieces of rocks and minerals b. Chemical – made from evaporation process or chemical changes of a mineral c. Organic- made of up once living material (fossil fuel or has fossils in it)

5 Do Now: Types of Cleavage Describe and provide an example 1. Cleavage in one direction: 1. Flakes, or thin sheets 2. Micas, Hornblende and Talc (small flakes) 2. Cleavage in two directions 1. At least two flat edges not always 90° 2. Feldspars 3. Cleavage in three directions at 90° 1. Cubic cleavage 2. Halite, Galena, Pyrite 4. Cleavage in three directions NOT 90° 1. Slanted corners 2. Calcite 5. Cleavage in four directions 1. Crystal – four to six sides 2. Quartz 6. Concoidial 1. Rounded sides 2. Sulfur

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

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

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

9 Do Now-Rock Review (TYPE and NAME) Sedimentary Marble Conglomerate Sedimentary shale Sedimentary Schist Metamorphic Obsidian Igneous gneiss Metamorphic Igneous granite Igneous sandstone Igneous Pumice Metamorphic Scoria

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

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

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

13 Do Now-Sedimentary Rocks- Answer in your new Do Now Chart 1. List and Describe the THREE types of Sedimentary Rocks. Then, provide an example for each TYPE of sedimentary rocks. A. Clastic - B. Chemical - C. Organic - Made up of piece of rocks that are cemented together. 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: Organic Shale Geode Chemical Conglomerate Clastic

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

15 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: Name: Intr/Extr: Name: Intr/Extr: Name: Intr/Extr: Scoria Extrusive Intrusive Pumice Granite Extrusive Obsidian Extrusive

16 Do Now: 1. What are the TWO types of Igneous Rocks? Describe and Provide an example of each. Extrusive- forms on the surface of the earth from lava or a volcano (Examples: Pumice and obsidian) Intrusive- forms from magma under the earth’s surface (Examples: granite and basalt) 2. 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) 3. How do Igneous rocks form? From the heating and cooling or lava and magma 4. How do Metamorphic rocks form? From heat and pressure deep within the earth’s crust

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

18 Name these minerals and state something unique about each mineral: Orthoclase Feldspar Gypsum Muscovite Mica GraphiteFluorite Talc Galena Calcite Biotite Mica

19 Do Now-Rock Review (TYPE and NAME) Sedimentary Marble Conglomerate Sedimentary shale Sedimentary Schist Metamorphic Obsidian Igneous gneiss Metamorphic Igneous granite Igneous sandstone Igneous Pumice Metamorphic Scoria
