Objective: Identify physical properties of common minerals.

Essential Question:What physical properties can you use to identify and describe minerals?

Home Learning:

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 mineralsC. examining the color the mineral makes when rubbed across porcelainD. feeling the mineral to determine if it is rough, smooth, greasy, or glassy Florida Achieves

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

Sedimentary

Igneous

Metamorphic

Rock Type Photographs and more: http://geology.com/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 weightSee http://geology.com/rocks/sedimentary-rocks.shtml for photographs and more.

*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

igneous rock.

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 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.

*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?

Identify the causes of weathering and erosion.

Identify the differences between weathering and erosion.

Essential Questions:

What are the forces (physical agents) that cause weathering?

How does water and ice wear away a rock?
