Presentation on theme: "MineralsMinerals. Question of the Day Question: Describe 2 of the stations from your minerals lab. Answer: ……… Turn In: Classifying Items Minerals Lab."— Presentation transcript:
Station1- The Dark Side There were 6 different minerals in this set NumberMineral 1Hornblende 2Biotite 3Magnetite 4Graphite 5Hematite 6Augite Different minerals can be similar in color!
Station 2: Varieties of SiO 2 There was only 1 mineral in this set - quartz A single mineral can be a variety of colors!
Station 3: Mellow Yellow There were 3 minerals in this set – native copper, pyrite, sulfur NumberMineral 1Sulfur 2Pyrite 3Copper A few minerals have a unique color!
Station 4: Streak – Powder Power Mineral Number Apparent Color Streak ColorMineral Name 1BlackReddish brownSpecular Hematite 2BlackReddish brownHematite 3GoldBlackPyrite 4Pinkish Orange No streakFeldspar 5Black Graphite 6PinkNo streakRose Quartz Streaking is a reliable way of identifying similar-appearing minerals!
Station 5: Luster – Shine On Mineral Number Luster (circle one) Luster (if non-metallic) Mineral 1metallic Specular Hematite 2non-metallicEarthy/dull Sulfur 3non-metallicVitreous/ glassy Quartz 4non-metallicVitreous/ glassy Biotite 5metallic Pyrite 6metallic Hematite 7non-metallicPearly Talc Luster is the quality of light reflected off a mineral.
Station 6: Cleavage-Them’s the Breaks Mineral # Sketch of Mineral Sketch of Smallest piece Mineral Name 1-------------- do not attempt to cleave this mineral ------------------------- Quartz 2 Halite 3 _______________ Biotite 4 _______________ Muscovite 5 Calcite Cleavage is when a mineral naturally breaks along a flat surface.
Station 7: Hardness-Let’s be Abrasive Mineral Number HardnessMineral A7Quartz B1Talc C6Feldspar D3Calcite E4Flourite Moh’s Scale is a measure of hardness.
Station 8: Optical Properties- To See or Not to See Mineral Number Optical Property Displayed Mineral 1Translucent Quartz 2Transparent & Double Refraction Calcite 3Translucent & Fiber Optics Ulexite 4Transparent Gypsum 5Opaque Muscovite
Station 9: Calcite Test – The Acid Test ReactantsProducts 2 HCl + CaCO 3 CaCl 2 + 2 H 2 O + CO 2 (g) List the five elements present on the left side of the equation. H, Cl, Ca, C, O What is the formula for hydrochloric acid? HCl Calcite is one of the reactants. What is the formula for calcite? CaCO 3 On the right side of the equation, what five elements are present? H, Cl, Ca, C, O On the right side of the equation, what three compounds are produced? CaCl 2, H 2 O, CO 2 One of the products is a compound called Calcium Chloride. What is its formula? CaCl 2 Why does the calcite fizz in acid? CO 2 gas is being released Mineral Number Fizzes? Mineral 1 NoMuscovite 2 NoQuartz 3 YesCalcite 4 NoGypsum
Station 10: Definitions – Play by the Rules Sample Number Mineral? (yes or no) Reason why you classified it as a mineral or not a mineral. 1NoOrganic (made from a living thing) - wood 2NoMan-made – glass 3NoNot made of crystals, man-made (metal) 4NoOrganic (made from a living thing) (coal) 5NoNot a uniform composition (rock) 6NoNot a uniform composition (rock) 7YesSpecular Hematite 8YesFeldspar All minerals have 5 properties: natural, same composition, solid, inorganic, and crystalline.
Station 11: Density Sample Letter DensityIdentity A 3.05 Quartz B 5.25 Pyrite C 4.5 Hematite D 4.5 Specular Hematite E 2.75 Hornblende
