January 12th
Get your composition book and your science book and
sit down and answer the following questions in your
composition book.
1. What are the four characteristics of minerals?
1. Formed in Nature – Inorganic
2. Solid
3. Crystal Structure
4. Definite Chemical Make-up
2. What are the four layers of the Earth?
1. Crust
2. Mantle
3. Outer Core
4. Inner Core
Notes - Jan. 12th
All Minerals are made up of Elements
Inorganic means made from a non-living substance
Solid - Matter with a definite shape and a definite volume
The more pressure the tighter the bonds in the crystal
structure (example diamond and graphite)
January 13th
Get in your seat/groups and then answer the
following questions in your composition book.
1. List the five ways that minerals form?
1.
2.
3.
4.
5.
Water Evaporates
Hot Water Cools
Molten Rock Cools
Heat and Pressure cause changes
Organisms produce minerals
2. What is the most common group of minerals?
Silicates
They contain oxygen and silicon the two most common elements in the Earth’s crust

Water Evaporates
● Water evaporates along the shoreline
● Leaves behind substance that were
dissolved in that water
● The substances CRYSTALLIZE together to
form a mineral
● Examples - Halite and Gypsum
Notes Jan. 13th
Hot water Cools
● Hot water dissolves minerals in the crust
● The water cools and the dissolved minerals
separate and CRYSTALLIZE into a solid
● Atoms can join together and make new
minerals
● Examples - Gold and Galena
Notes Jan. 13th
Molten Rock cools
● When Magma (below Earth’s surface) cools
and CRYSTALLIZES
● Magma cools and atoms join to form
different minerals
● Lava (reaches Earth’s surface)
CRYSTALLIZES
● Examples - Quartz and Mica
Notes Jan 13th
Heat and Pressure cause change
● Heat and Pressure cause minerals to form
new minerals - bonds break apart and
RECRYSTALLIZE into new ones
● The more pressure the stronger the bonds
● Examples - Graphite and Diamond
Notes Jan. 13th
Organisms produce minerals
● There is always an exception - a few
minerals are made by living organisms
● Oysters, clams, and even you produce
minerals - these minerals are also produced
in nature by non-living substances
● Examples - Apatite and Calcite
January 14th
Get your book and composition book, sit down, and
answer the following questions!
1. How is Halite (rock salt) formed?
Halite is formed when water evaporates!
2. All substances must ______________ before turning into a
solid mineral.
CRYSTALLIZE
Jan. 15th and 16th - Computer Lab
Gizmo on Mineral Identification
Group A - White Paper
Group B - Pink Paper
Group C - Gold Paper
Jan. 20th
Get your composition book, your science book, and a chromebook. Then
answer the following questions.
1. What is the luster of a mineral? How do you find it?
Luster is the way light reflects off a mineral. You find the luster by looking at
the mineral in the light.
2. What is the streak of a mineral and how do you find it?
Streak is the color of the powder that is left behind when a mineral is rubbed
across a streak plate. You find streak by using a streak plate and rubbing the
mineral across it.
