Bell Work 9/20/11

Complete the PPOC on the back of your “Improve” paper for the Survivor Stranded Lab. You will be turning this in for your

grade for the lab. Purpose:

Outcome:

Conclusion:

Observe the photo on pgs. 334 & 335 in your textbook.

Read the caption titled, “About the Photo.”

Answer the following questions:◦What is a mineral?◦What does the caption tell you about minerals?

What is a mineral?A _________is a naturally formed,

inorganic solid that has a definite crystalline structure.◦naturally◦inorganic◦solid◦crystalline (structure)

mineral

Mineral StructureBy answering these four questions, you

can tell whether an object is a mineral:1. _________________ A mineral is inorganic,

meaning it isn’t make of living things.2. __________Minerals can’t be gases or liquids.3. ___________________________Minerals are

crystals, which have a repeating inner structure that is often reflected in the shape of a crystal.

4. ________________ Crystalline materials made by people aren’t classified as minerals.

Is it nonliving material?-Is it a solid?-Does it have a crystalline structure?-

Is it formed in nature?-

Identifying MineralsThe following pictures are in your

group: wood, fossil, bone, granite, quartz crystal

Observe the pictures and determine which ones are minerals by using the four questions.

Write down the names of each item and “yes” if it is a mineral and “no” if it is not a mineral.

Group Activity!

Mineral Structure_________ are pure substances

that cannot be broken down into simpler substances.

All minerals contain one or more of the 92 naturally occurring elements.

Elements

Check

this out!

Atoms and CompoundsEach element is made of only one

kind of _______.An atom is the _________ part of an

element that has all the properties of that element.

Some properties of aluminum are: shiny, silver colored, fragile, and thin. Each element has its own type of properties.

Most minerals are made of __________ of several different elements.

A compound is a substance made of ___ or more elements that have been chemically joined or ________.

A Carrot

The smallest particles of matter are called atoms.

Let’s take a carrot for example. If you continue to chop a carrot into smaller and smaller pieces, eventually you would reach a point where you could not cut up the carrot anymore, but still have carrot. You would then have molecules of carrot.

The same applies to elements. If you continually cut up a piece of aluminum, you will reach a point that you could no longer divide it. These are aluminum atoms.

Atoms Elements Compounds (Minerals)

CrystalsSolid, geometric forms of minerals

produced by a repeating pattern of atoms or molecules that is present throughout the mineral are called ________.

A crystal’s shape is determined by the arrangement of the atoms within the crystal.

crystals

Two Groups of MineralsSilicate minerals are minerals

that contain a combination of silicon, oxygen, and one or more metals.

Nonsilicate minerals are minerals that do not contain a combination of silicon and oxygen. There are six main classes of nonsilicate minerals.

Two Groups of MineralsWrite the names of

the two groups on the front of the foldable (one on each side).

Inside (on the notebook paper) use Figures 4 & 5 on pages 338-339 to take notes on the two groups. Include the definition of the two groups and examples with descriptions.
