  2. This is this…

  3. What is this?

  4. This is this…

  5. This is this.

  6. These are these.

  7. These are Minerals.

  8. What are Minerals? • Cornell Notes Page 127

  9. What are atoms? • ATOMS =BUILDING BLOCKS ofeverything in the Universe.

  10. What is an element? • A substance that cannot be broken down into simpler things. • Examples: Gold, silver, aluminum

  11. What is a compound? • A substance made of more than one element • Examples: Water, table salt

  12. MINERALS 3,000 + different kinds of minerals Most are made of combinations of elements (compounds)

  13. 5 Characteristics of Minerals • 1. Naturally occurring • 2. Inorganic =not from a living thing

  14. 45 seconds to Discuss… • What does it mean to be “naturally occurring?” • What does it mean to be “inorganic?”

  15. Pyrite in rock • 3. Solid • 4. Crystal Structure –particles line up in a pattern

  16. 45 seconds to Discuss… • What does it mean to be “solid?” • What does it mean to have a “crystal structure?”

  17. Examples of solid, crystal structure • Rhodochrosite

  18. A mineral… • 5. Definite Chemical Composition Ex.) Water = H2O Salt = NaCl

  19. Calcite—has the chemical name--CaCO3 An example of: definite chemical composition • http://education.jlab.org/indexpages/teachers.php Ca=Calcium (as in your bones) C=Carbon (in all living things) O= Oxygen (in the air) http://teach.fcps.net/trt20/projects/EKU/Minerals/groups/mineral_groups.htm

  20. 60 seconds to Discuss… • What do we mean by “chemical composition?” • So then what does it mean to have a “definite chemical composition?”

  21. Quartz = SiO2 What are the two groups of Minerals? • Silicate Minerals • chemical composition with a combination of Silicon and Oxygen

  22. Nonsilicate Minerals • Do NOT contain a combination of silicon and oxygen.  Fluorite = CaF2

  23. 45 seconds to Discuss… • How are Silicate Minerals and Nonsilicate Minerals different?

  24. What’s in these minerals/rocks that look so delicious? Oxygen Silicon Aluminum Magnesium Iron Sodium Calcium Potassium http://www.geolsoc.org.uk/gsl/education/page2659.html

  25. The result of eating rocks and minerals…

  26. What is from minerals in the room? What is NOT from minerals in the room? • 1. • 2. • 3. • 4. • 5. • 6. • 7. • 8. • 9. • 10. • 1. • 2. • 3. • 4. • 5. • 6. • 7. • 8. • 9. • 10.
