Do Now 2/261. How do you find the Hardness of a Mineral?
1-2 Mineral Can be scratched with your fingernail2-3 Mineral can be scratched with a penny4-5 Mineral can SCRATCH THE PENNY6-7- Mineral can scratch glass7-8- Mineral can scratch steel8-9 - 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:
GraphiteGlassy Quartz
Dull Kaolinite- chalk
Pearly Muscovite Mica
Metallic
1. What is the name of this 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. Are minerals organic or inorganic and what does organic/inorganic mean?
Galena
Metallic
Inorganic- NOT made of living things
Sulfur

1.What is the difference between fracture and cleavage?
List 3 minerals with Cleavage:
Do Now 2/27:
List 3 minerals with Fracture:
1. 1.2. 2.3. 3.
2. What DO YOU BELIEVE is the difference between rocks and mineral?
Fracture has NO SPECIFIC shape in the way the mineral naturally breaksCleavage does have some kind of specific shape in the way it breaks
Halite- Cubic
Mica- This sheets
SulfurCalcite- Rhombic
Graphite
Fluorite
Minerals have specific chemical composition and chemical structureRocks are made up of different minerals
Do Now- Name and answer question for each:
Hardness? Hardness? Cleavage?Ore for?
Ore for? hardness? Ore for? Cleavage?
Talc, 1 Fluorite, 4 Orthoclase Feldspar, 2 directions
Galena, lead
Hematite, ironCorundum, 9 Bauxite,
Aluminum
Calcite, 3 directions NOT

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 mineralexample: Limestone and geodes
Made up of living material
Example: coal or limestone
USE the Rock KEYS to identify the Sedimentary rocks below:
Organic
ShaleGeode
Chemical
Conglomerate
Clastic
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
Do Now- Igneous RockList the name of the following rocks, type of igneous (intrusive/extrusive) and how the rocks were formed.
Name:Intr/Extr:

Do Now:1. 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)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
