2.  Students will: -identify the characteristics of minerals. -explain how minerals are classified into groups. -identify which mineral group is most common

3.  Decide if these statements are true. If not, correct them. 1. Latitude is a distance in degrees north or south of the equator. 2. Convection requires touch while conduction requires heat rising and cool air sinking. 3. Rocks and minerals are the same.

5.  We use minerals everyday  Minerals are found in many things in the house and classroom.

6. 4 characteristics of minerals:  Forms in nature  Is a solid  Has a definite chemical composition  Has a crystal structure  mineral-a substance that forms in nature, is a solid, has a definite chemical composition and a crystal structure

7.  element—a substance that contains only one type of atom  crystal—a solid in which the atoms are arranged in an orderly repeating 3D pattern.

8.  forms by a natural process, a cycle  a mineral cannot be a liquid or gas  each mineral has a specific combination of elements. Some minerals have the same composition, but their structure differs. Example: graphite and diamond are both made up of only carbon, but differ in their structure.

9.  Minerals are grouped by what they are made of (what they are composed of..)  Some groups include: › Silicates  make up about 90% of the rocks in Earth’s crust. › Carbonates › Oxides

10.  Rocks and minerals are not the same! › Minerals have 4 characteristics while rocks only have 2 › Structure is different: minerals always have the same elements in the same proportion, rocks do not. › Crystal structure: minerals have an orderly structure, rocks are jumbled together.  rock—a naturally formed solid that is usually made up of one or more types of minerals
