Minerals!They're everywhere!What are they?
Nov 174:11 PM
To be a mineral you need to be in the special club. In order to be in the special club you need...
5 characteristics...
Nov 189:36 AM
1. Naturally occurringNaturally Occurring means that is was made by nature, not made by man or machine
Nov 189:51 AM
2. InorganicInorganic means that it has not been made from living things, or has parts of living things in it.
Nov 189:33 AM
3. SolidSolid means it has a specific, rigid shape and volume. It cannot be a liquid!
Nov 1810:10 AM
4. Definite shapeA definite shape means that the mineral has a specific crystal shape when it forms
Sometimes the crystals in a mineral are soooo small you can only see them with a microscope, but they arestill there, you just can't see them!

5. Definite chemical compositionA chemical composition is what atoms the mineral is made up of. The chemical composition for a mineral is like a recipe. Just the way you need certain ingredients to bake a cake (eggs, flour, sugar, butter) each mineral needs certain atoms in certain amounts.
Feb 19:56 AM
Ca (PO ) (FCl OH)5 4 3
This is the chemical composition (recipe) for that awesome green mineral you are holding...it's called Flourite (seriously, it is!)
Nov 189:32 AM
Chemical composition also tells us whether a mineral is an element or a compound.What's the difference?
An element is a mineral that is made from only one type of atom
Like gold or sulfur or diamonds
A compound is a mineral that is made from at least two types of atoms and as many as 100 different kinds of atoms
Like sapphires, quartz, or graphite (pencil lead)

So... what is a mineral????A mineral is a naturallyoccurring, inorganic, solid with a definite crystal shape and chemical composition!!!
WOW!!!Can you be in the club?....
Heck no!You are organicand...you don't have a crystal shapeand...you don't have a definite chemical composition.

Can a pearl be in the club?
Can an ice cube be in the club?
Can water be in the club?
Can your sandwich for lunch be in the club?
Can Mr. Hansberry be in the club?

all right, so we know it's a mineral...
But how do we know WHICH mineral it is (or if its valuable)
Nov 1811:25 AM
In order to tell WHICH mineral it is that we are looking at..... (is it quartz or a diamond!!!!?)
we perform 8 experiments on it!(bwaa haha!)
No, we do not strap the cute little mineral down on a tray and torture it...
1. we LOOK at it closely,2. we scratch it with something3. we scrape it along an unglazed tile4. we shine a light on itand other fun things like that!
Nov 1811:54 AM
Nov 1811:50 AM
Experiment 1: COLOR!
Nov 1811:51 AM
Experiment 2:Luster!a. Does it shine like polished metal? (metallic)
b. Is it shiny but doesn't look like metal? Is it dull or pearly?(nonmetallic)
Metallic Nonmetallic

Experiment 3:Cleavage/Fracture
When the mineral is broken it will either break on a smooth surface (cleavage)or in a ragged, fiberous, rough way (fracture)
Nov 1812:15 PM
Experiment 4Streak!The streak of a mineral is the color of the powder that is left behind when it is scraped along an unglazed tile.
Nov 1812:15 PM
Experiment 5:DensityThis can be measured by it's weight or heft, but there are other, more scientific ways to measure density also.
Nov 1812:23 PM
Experiment 6:HardnessSome mineral are very soft and some are very hard. All mineral of a one type will all have the same hardness, Some minerals are so soft they can be scratched with a fingernail while others are so hard they are used to cut metal and class!
Some ways you can test a mineral's hardness is to... Scratch it with your fingernail Scratch it with a penny Scratch it with a steel nail
Nov 1812:24 PM
...There once was a cool guy named Mr. Mohs....He liked to look at and experiment on minerals!(cool, hunh?)
Mr. Mohs put together a list of 10 common minerals that ranked them in order of their hardness. The softest common mineral is Talc (ground up it makes baby powder
or talcum powder!) See! You put mineral in between your toes and didn't even know it!
The hardest common mineral is Diamond (they sparkle and are really pretty!) Aren't minerals wonderful?
His list was called Moh's Hardness Scale.
Nov 1812:52 PM
Experiment 7:Crystal shape
There are 6 common crystal shapes that crystals can take...RhombicCubicHexagonalTetragonalOrthorhombicTriclinic

Experiment 8:Special properties!A mineral can show many special properties! These properties can usually distinguish the mineral right away.Some common special properties are...Smell (such as sulfur)Taste (salty like halite...salt)Magnetism (such as lodestone/magnetite)Fluorescence (such as scheelite)Radioactivity (such as uraninite)
Nov 1811:25 AM
So let's review!There are 5 characteristics that a substance needs to have in order to be considered a mineral1. Naturally occurring2. Inorganic3. Solid4. Crystal shape5. Chemical composition
Once a substance is determined to be in The Mineral Club, you can perform 8 different tests/experiments on it to find out which mineral it is1. Color2. Luster3. Cleavage/Fracture4. Density5. Hardness6. Streak7. Crystal shape8. Special properties

Chapter 2: Minerals
Section 1:Properties of Minerals
Objectives:
1. Identify the characteristics of a mineral
2. Identify the properties of a mineral and describe how they are identified.
Key Terms:
1. Mineral 2.Inorganic, 3.Crystal 4.Element 5.Compound
6. Mohs Hardness Scale, 7.Streak 8.Luster 9.Cleavage 10.Fracture
11.Flourescence
1. What is a mineral? ___________________________________________ ____________________________________________________________________________________________________________________________
2. Give an example of something that is considered “naturally occurring” ____________________________________________________________________________________________________________________________
A. Something that isn’t naturally occurring is considered man made!
3. What is the difference between an organic substance and an inorganic substance? Give an example of each. ______________________________ ____________________________________________________________________________________________________________________________
4. When we discussed crystal structure in class, what did Mrs. Mayo say the building of a crystal was like?______________________________________ ______________________________________________________________
A. Can you always see the mineral’s crystal structure? ___________________________________________________________
5. What is the difference between an element and a compound? Give an example of each. _______________________________________________ ____________________________________________________________________________________________________________________________
6. There are 8 ways to make sure the mineral you are looking at is properly identified (or put into a category) List the 8 different tests you can perform on a mineral to correctly identify it
A. ___________________________________________
B. ___________________________________________
C. ___________________________________________
D. ___________________________________________
E. ___________________________________________
F. ___________________________________________
G. ___________________________________________
H. ___________________________________________
7. What is the difference between cleavage and fracture? __________________ ______________________________________________________________
8. What scale is used to determine the hardness (or resistance to scratching) a mineral has? __________________________________________________
9. What is the softest mineral? _______________________
10. What is the hardest mineral? ______________________
11. What are the two types of luster a mineral can have?
A. ____________________________________
B. ____________________________________
12. Give an example of a special property a mineral might have. _____________
Key Ideas for this section:
1. A mineral is a naturally occurring, inorganic solid with a definite crystal shape and chemical composition.
2. Each mineral is different from all the other minerals and has it’s own chemical and physical properties to help identify it.
3. Some of the properties of mineral include: hardness, color, streak, luster, density, cleavage and fracture, and crystal structure. Hardness is measured on the Mohs Hardness Scale
4. Mineral usually consist of two or more elements joined together in a compound.
