What is a Mineral? SPI 0707.7.1 (Minerals) In your journal, create KWL chart. Be prepared to write the things you know, what to know, and learn about minerals

Minerals are… 1. Natural 2. inorganic (never alive) 3. Solid 4. Crystalline (structure) SPI 0707.7.1 (Minerals)

How can I tell if something is a mineral? Answer these four questions: Is it nonliving material? Is it a solid? Does it have a crystalline structure? Is it formed in nature? --If the answer isn’t “yes” to all 4 questions, then it’s not a mineral!!!

Is it non-living? A mineral is inorganic, meaning it isn’t made of living things

Is it solid? Minerals can’t be gases or liquids, they can only be pure solids.

Does it have a crystalline structure? Minerals are crystals, which have a repeating inner structure that is often reflected in the shape of the crystal. Minerals generally have the same chemical composition throughout.

Is it formed in nature? Minerals are formed naturally. Crystalline materials made by people aren’t classified as minerals!

Group Activity! Identifying Minerals The following pictures are posted: wood, fossil, bone, granite, quartz crystal Observe the pictures and discuss with your group 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.

Two Groups of Minerals Write the names of the two groups on the front of the foldable (one on each side). Use pages 338-339 to take notes on the two groups. Include the definition of the two groups and examples with descriptions. Silicate Minerals Nonsilicate

Contain a combination of silicon, oxygen, and one or more metals. Silicate Minerals Contain a combination of silicon, oxygen, and one or more metals. Mica Quartz Feldspar

Nonsilicate Minerals DO NOT contain compounds of silicon and oxygen, BUT can contain carbon, fluorine, and sulfur. Six groups Calcite Fluorite
