FCAT 2.0 Question SC.4.E.6.2
Eddy is trying to identify a mineral by observing its
luster. This means that he is doing which of the
following?
A. observing the way the mineral reflects light
B. scratching the mineral with other objects or
minerals
C. examining the color the mineral makes when

Minerals and You
Every solid material made from nature
that is NOT a plant or animal (not a
living thing) is a mineral or made from
minerals. Minerals touch our lives in
hundreds of ways each day. Life as we
know it would not exist without them.
* A solid material that is formed by nature in or on Earth’s
crust
* A material that has a crystal form
* A material that is not formed by a living thing

A rock sample will most likely contain
A. water.
B. wood.
C. plants.
D. minerals.
Objective:
Observe and describe three categories of rocks:
igneous, (formed from molten rock); sedimentary
(pieces of other rocks and fossilized organisms); and
metamorphic (formed from heat and pressure).
Essential Question:
How are rocks formed and classified?
Home Learning:
Rocks …
*Solid earth material
*Make up the crust of the Earth
*Mixture of one or more minerals
*Range in size from giant mountains to grains of sand
*Can be smooth or rough, shiny or dull, one color or
many colors
Three Types of Rocks
Sedimentary
Igneous
Metamorphic
Rock Type Photographs and more: http://geology.com/rocks/
Sedimentary Rocks
* Form when layers of rock particles get pressed together at or
near Earth's surface
https://www.pearsonsuccessnet.com/snpapp/login/login.jsp
* Nickname = “Layered” rocks
* May contain fossils
* Common near bodies of water or where water existed in the
past
* Characteristics:
Layers
Loosely compacted
Distinct particles
Dull
Light colored
Light weight
See
http://geology.com/rocks/sedimentary-rocks.shtml for photographs and more.
Igneous Rocks
*Form when magma (hot liquid rock) cools and
hardens
*Cools very fast = glassy with holes
*Cools fast = glassy
*Cools slow = small crystals
*Cools very slow = large crystals
*Nickname= “Fire formed” rocks:
Pumice is a gas-charged

Metamorphic Rocks
*Form when underground rocks are changed due to high
pressure
*Nickname = “Changed” rocks
*Common in mountains
*Characteristics:
Thick layers
Blended colors
Tightly compacted
Blurred particles
Shiny

Florida’s Natural Resources
Renewable or Non-Renewable
Objective:
* Distinguish between renewable and
nonrenewable resources.
* Identify resources found in Florida.
Essential Question:
What natural resources are necessary for
survival?
What natural resources are found in Florida?
Home Learning:
Water is a renewable resource found in Florida. The state
is surrounded on three sides by the Atlantic Ocean and the
Gulf of Mexico. It is also home to many inland freshwater
lakes and rivers. What makes water a renewable
resource?
a. It does not cause pollution.
b. It is constantly recycled so it can be used again.
c. It is necessary for all plants and animals to live.
d. It takes hundreds of years for water to be created after
it is used.

Water
Phosphate
Oil
Limestone
Silicon
Solar Energy
Wind Energy
Water is used in homes for household uses, in industry for
cooling and processing, in agriculture for irrigation, in
recreation, and is necessary for sustaining Florida wildlife.
Phosphate is a key ingredient in fertilizer. Since FL has the
largest deposits of phosphate in the US, it is a chief export.
Oil is used for providing heat, light, electricity, and gasoline.
Limestone is FL's most plentiful mineral and is used in
construction, roofing, and in making cement.
Silicon is used in the making of concrete, glass, and steel. It is a
key ingredient in abrasives and is used in making lasers.
Wind can be used to turn turbines to create energy.
Solar energy can provide heat, light, and electricity.

What are the differences between
renewable and nonrenewable
resources?
* Nonrenewable resources are resources that cannot be replaced in a
short amount of time.
* Unlike renewable resources, it is possible for humans to use up all of the
nonrenewable resources in the world.
* A renewable resource is a resource that humans are not likely to run
out of.
* Wind is a renewable resource because the wind will always continue to
blow on Earth.
* Trees are a renewable resource because they can be planted and grown
in a short amount of time.
Are our natural resources
renewable or non-renewable
resources?
