1. Bell Work 9/20/11Complete 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: • Procedures: • Outcome: • Conclusion:

2. 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?

3. What is a mineral? • A _________is a naturally formed, inorganic solid that has a definite crystalline structure. • naturally • inorganic • solid • crystalline (structure) mineral

4. Mineral Structure • By answering these four questions, you can tell whether an object is a mineral: • _________________ A mineral is inorganic, meaning it isn’t make of living things. • __________Minerals can’t be gases or liquids. • ___________________________Minerals are crystals, which have a repeating inner structure that is often reflected in the shape of a crystal. • ________________ 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?-

5. Group Activity! Identifying Minerals • The 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.

6. 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!

7. Atoms and Compounds atom • Each 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 ________. smallest compounds two bonded

8. 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.

9. Compounds (Minerals) Atoms Elements

10. Crystals • Solid, 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

11. Two Groups of Minerals • Silicate 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.

12. Two Groups of Minerals • Write 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. Silicate Minerals Nonsilicate Minerals
