Do Now 2/26 1._ _ Example: 2._________________ Example:
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
3
DO NOW- Minerals 1. What is the name of this very DENSE mineral?
Galena 1. What is the name of this very DENSE mineral? 2. What is the luster of this mineral? Metallic 3. What is the name of this mineral? 4. What is the hardness of this mineral? Sulfur 2.5- chips pieces 5. What is the name of this mineral that you can write with? Graphite 6. What is the hardness of the mineral? How do you know? 1- feels greasy

Do Now: Rocks List the three main types of rocks AND how they form.
Igneous- forms from lava or magma (melted rock above or below surface) Metamorphic- formed from heat and pressure (at times appears squished) Sedimentary- formed from pieces of other rocks or minerals through chemical or physical changes 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. Igneous Intrusive- forms from magma INSIDE the earth Extrusive-forms from lava on the exterior of the earth (volcanoes) Metamorphic Foliated- has crumpled lines or lanes Non-foliated-no crumpled layers Sedimentary Clastic- made of pieces of sand and/or pebbles of pieces of rocks and minerals Chemical – made from evaporation process or chemical changes of a mineral 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
Cleavage in one direction: Flakes, or thin sheets Micas, Hornblende and Talc (small flakes) Cleavage in two directions At least two flat edges not always 90° Feldspars Cleavage in three directions at 90° Cubic cleavage Halite, Galena, Pyrite Cleavage in three directions NOT 90° Slanted corners Calcite Cleavage in four directions Crystal – four to six sides Quartz Concoidial Rounded sides Sulfur
6
DO NOW- Provide, name, type of cleavage and hardness
Quartz 4 directions Halite 3 directions at 90° 7 Muscovite Mica one direction 2.5 2.5 4 5 6 Fluorite- fracture BUT sometimes 4 directions Talc- one direction (very hard to see) Calcite- 3 directions NOT 90° 1 4 3
7
Do Now- Name and answer question for each:
Hardness? Hardness? Cleavage? Ore for? Fluorite, 4 Orthoclase Feldspar, 2 directions Talc, 1 Galena, lead Ore for? hardness? Ore for? Cleavage? Corundum, 9 Calcite, 3 directions NOT 90° Hematite, iron Bauxite, Aluminum
8
Name these minerals! Graphite Halite Sulfur Hematite Muscovite Mica
Kaolinite 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? 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
13
Do Now-Sedimentary Rocks- Answer in your new Do Now Chart
List and Describe the THREE types of Sedimentary Rocks. Then, provide an example for each TYPE of sedimentary rocks. Clastic- Chemical- 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: Clastic Organic Chemical Shale Geode Conglomerate
14
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
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: Scoria Name: Intr/Extr: Granite Extrusive Intrusive Name: Intr/Extr: Obsidian Name: Intr/Extr: Pumice Extrusive Extrusive
16
Do Now: 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) 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
17
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?
18
Name these minerals and state something unique about each mineral:
Muscovite Mica Gypsum Orthoclase Feldspar Talc Graphite Fluorite Galena Calcite Biotite Mica
19
