<p>Minerals Chapter 2 Class Notes</p><p>9/28/12 Students will be able to describe that rocks are made of minerals.</p><p>Rock vs. Mineral Investigation</p><p>1) Observe using hand lens a rock and mineral specimen 2) Sketch in pencil (use color pencils to capture colors) Make your observations as detailed as possible 3) Write three detailed observations</p><p>Quartz Sketch Franklinite Sketch</p><p>10/1/12</p><p>Students will be able to name the 3 minerals that make up the rock Granite.</p><p>Salt Crystal (NaCl)</p><p>Rocks are mixture of minerals.</p><p>The Rock Granite is composed of Mica, Quartz, and Feldspar minerals.</p><p>Red = Feldspar Black = Mica White = Quartz 10/18/12 Objective – Students will be able to explain the relationship between elements as resources, minerals, ores, and mining.</p><p>Ore - A rock that contains enough of a valuable mineral to be mined for a profit. Streak – The color of a mineral powder left behind when a mineral is scraped across a surface. A method for classifying minerals.</p><p>Luster – the way in which light reflects from a minerals surface, a measurement of the amount of metal a mineral contains.</p><p>Streak Plate – a piece of un-glazed porcelain, that is used to test the color of the powdered form of a mineral.</p><p>10/11/12 Objective – Students will apply their understanding of color, streak, and luster to analyze rock and mineral samples.</p><p>Cleavage – the property of a mineral that describes its tenency to break along flat surfaces.</p><p>Fracture – the tendency of a mineral to break into irregular pieces</p><p>Density – a property of matter representing the mass per unit of volume</p><p>Mineral Investigation</p><p>Mineral # Color Streak Luster 1 Black Black Non-metalic 2 Brownish pink with black spots White Non-metalic 3 Grey Grey Metalic 4 White None Non-metalic 5 Blue/black/white Black/grey Non-metalic</p><p>10/12/12 Objective – Students will be able to apply their understanding of cleavage and fracture to classify some sample minerals</p><p>Examples of Cleavage – </p><p>Muscovite Calcite</p><p>10/17/12 Objective – Students will be able to complete simple density calculations</p><p>Density (g/cm3) = Mass (g/cm3) ------Volume (cm3)</p><p>10/18/12 Objective – Students will be able to name the 10 minerals that compose the Mohs hardness scale</p><p>Mohs Hardness Scale</p><p>Rating Test Mineral (Book) 1 Talc 2 Selenite (Gypsum) 3 Calcite 4 Fluorite 5 Apatite 6 Microcline (Feldspar) 7 Quartz 8 Topaz 9 Corundum 10 Diamond</p>
