Mineral Tests
How do you calculate a minerals density?
Triple points if you beat me in rock paper scissor
Mass/Volume
What is the mineral characteristic that says all minerals are made by the Earth (not produced in a lab)?
Naturally Occurring
What is the hardest mineral known to man? What number of hardness does this mineral have on Moh's hardness scale?
Diamond, 10
A true mineral can be formed in a lab: True or False
False (naturally occuring)
What do minerals make up?
Rocks
Why do scientists not rely on color alone to identify minerals?
Many minerals come in the same colors.
The characteristic that says minerals are not composed of living things.
Double points if you can sing the whole mineral song
Inorganic
What is the weakest item you can scratch that has a hardness of 2.5? Hint: This item is always with you
Fingernail
Minerals are still considered minerals if they are liquid or gas
Double points if you can draw a picture and we can guess what it is (has to be about minerals)
False
When building a structure would you use rock made of calcite or quartz? Why?
Double points if you beat a person of my choosing in Thumb war
Quartz, harder and does not fizz in acid
What is a mineral's streak and how is it tested?
Minerals color in powdered form. Rub on streak plate.
The state of matter a mineral will ALWAYS be found in.
Solid
A mineral can scratch a fingernail (2.5) but not a penny (3.5) what is the hardness?
3
A mineral can be formed without a crystalline structure, true or false
false must have a crystalline structure
Describe the chemical composition of a diamond found in Maryland vs a diamond found in Africa.
They are the same
Provide the definition of hardness and how each mineral's hardness is measured.
The ability of minerals to scratch or resist scratching of other materials. Measured by the scratch test.
This mineral characteristic says that all minerals must have a shape of atoms that determine the shape and arrangement of the mineral.
Crystalline Structure
What is the hardness of a glass plate? What does it mean if a mineral can scratch it?
5.5, the mineral is harder than 5.5
Name at least 3 things mineral formation is used for in the real world
technology, construction, fuel, jewelry, etc.
Name a mineral and its real world use.
ex ruby/diamond jewelry
halite salt
Provide the definition of luster an provide at least 3 examples of luster.
The way a mineral reflects light (shiny)
ex: pearly, dull, metallic, non metallic, glassy, resinous, etc.
Same chemical composition throughout
A mineral can scratch a fingernail and a penny (3.5) but cannot scratch glass. What are each of the hardness's that mineral might be?
4,4.5,5
Minerals can be formed from magma, dissolving in water, and evaporation.
True
What is the difference between cleavage and fracture?
Cleavage: smooth breaks Fracture: rough jagged breaks
