    1. If your fingernail can easily scratch the mineral, what is the hardness of this mineral? 2. A student notices that their unknown mineral will scratch a penny but it will not scratch an iron nail. What mineral might this unknown be? 3. What if the unknown mineral scratches all the common objects listed in the chart? Monday, September 9 Warm-Up (1 or 2) (4, Fluorite) (7 or greater)

    2. Where are they now?

    3. MYP Unit Question: What’s a world without rocks? Area of Interaction:Human Ingenuity Learner Profile:Thinker Standard: Students will investigate the scientific view of how the earth’s surface is formed. Learning Target: Today I am learning about the properties of minerals because minerals are in everything around me. T

    4. Opening: Brain-PopCrystals • Work Session: • Finish Notes over Minerals • What’s up next: • Notebook Check • “Wanted Mineral” due Tuesday • Test over minerals Wednesday • Bring cookies for editable lab.

    5. Crystal Structure • The particles of the material line up in a regular, repeating pattern. • Has flat sides called faces, that meet at sharp edges and corners. is a result of a repeating pattern.

    6. The repeating pattern is a result of • atoms bonding together chemically • forming compounds.

    7. Definite Chemical Composition • Always contains certain elements in the same proportion. • Pyrite is two sulfur atoms bonding with one atom of iron. FeS2

    8. Chemical Formulas Ruby Al2O3 • Coefficients (big numbers) tell how many atoms of each element is in the compound. • Subscripts (small numbers) tell how many of the atom before it that you have.

    9. Native Elements • Are made from just one element. Copper = Cu Diamond = C

    10. How do minerals form? 1. When liquid rock from inside the earth cools and hardens. • Cools Slowly • LARGER crystals • Cools Quickly • SMALLER crystals

    11. Granite

    12. 2. When a mineral is dissolved in a liquid • Liquid evaporates Slowly = LARGER crystals • Liquid evaporates Quickly = smaller crystals Halite, Calcite, Gypsum, Limestone

    13. Divided into two groups based on mineral composition Silicate minerals Non-silicate minerals Groups of Minerals

    14. Made of silicon and oxygen, the most common elements in the Earths crust (90%) Quartz Feldspar Mica Silicate Minerals

    15. Non-Silicates • Usually contain carbon, oxygen, fluorine, and sulfur.

    16. Closing: Luck of the Draw In 3 or 4 sentences, summarize today’s lesson. Person seating in seat #16
