Minerals
What is a mineral?
• Naturally occurring (comes from nature, not a laboratory)
• A solid (well unless it finds itself inside the earth in the mantle!)
• Inorganic (was never a living thing)
• Has a fixed chemical formula
• Has an ordered crystal structure
Where are minerals found?
All over earth! On the surface or crust,
in the mantle, and even in the ocean!
Rocks!Remember that rocks are made up of one or more
minerals!
Why are minerals important?
We eat them!We drink them!We wear them!We live in them!We talk on them!
We clean with them!We use them for our health!
We watch them!We ride in them!We spend them!
WE USE THEM EVERYDAY!!!

Mineral Scavenger Hunt
1.Each mineral basket will rotate from table to table.
2.Study the products that come from minerals.3.Do not open the items!4.Look at the ingredient list and see what
minerals are in the product.5.Find the mineral on your mineral list.6.Write the product name next to the mineral.
When you finish, decide which mineral is your favorite!
Homework: Take your list of minerals and search your home for more products that contain
minerals that your family and you use everyday!
How can you tell one mineral from
another?How can you
classify minerals?
That’s for tomorrow when you become a
Little River Mineralogist!
Mineral Properties(how minerals are identified)
• Streak – color of the powder left behind
• Luster – way the mineral surface reflects light
• Hardness – the minerals’s ability to resist being scratched
(Tested according to Moh’s Hardness Scale)
• Clevage – direction minerals break apart
• Color
Moh’s Hardness Scale
Used to measure A mineral’s abilityto resist beingscratched.
MOHS SCALE OF HARDNESS - a scale devised by Friedrich Mohs
Scratching tools: fingernail (2.2) copper penny (3.5) pocket knife or common nail (5.2) piece of glass (5.5) steel file or concrete nail (7.5) piece of corundum (9)Each mineral can scratch the minerals with lower hardness ratings. Each mineral can scratch itself.
