1. Bell Work 9/2/141What element is Group 1 and Period 4?Potassium2. What is that element’s atomic number?193. How many electrons does it have?194. What is its atomic mass? 39.0985. How many neutrons does it have?39 – 19 = 20On your desk :PRIDE cardINPencil/Pen
2. Properties of MINERALSAdd to your Table of Contents!!
3. A mineral is a naturally formed, inorganic solid that has a definite crystalline structure.What is a mineral?
4. Mineral GroupsEverything on Earth is classified into various categories based on certain properties and minerals are no different!
5. 2 GroupsSilicate MineralsNon-Silicate Minerals
6. Silicate MineralsMinerals that contain Silicon, Oxygen, and one or more other element.Silicon and oxygen are the two most common elements in the Earth’s crustExamples: quartz, feldspar, and mica
7. Non-Silicate MineralsMinerals that do not contain a combination of silicon and oxygen. They may contain carbon, fluorine, and sulfur.Examples: copper, calcite, fluorite, corundum, gypsum, and galena
8. SolidCannot be a liquid, gas, or plasma.InorganicIt is non-living. It is NOT alive and never was.Naturally OccurringFound in nature, not man-made.Crystal FormA definite structure in which atoms are arranged.Minerals have 4 properties
9. Is it a solid?Is it Inorganic(non-living)material?Is it formed in Nature (not man-made)?Does it have a Crystalline structure?When trying to figure out if it is a mineral or not THINK SINC!!!!
10. ItemMineral OR Non-mineral?If Non-mineral: list the properties it doesn’t have (S,I, N, C)1.2.3.13.Output side of IN
11. WoodIs it a solid? YESIs it Inorganic (non-living) material? NOIs it formed in Nature (not man-made)? YESDoes it have a Crystalline structure? YESTHINK SINC!!!!

38. You now know how to identify if an item is a mineral!!NOW we need to learn how to identify specific types of minerals!!
39. Let’s get our READ-ON!Mineral IdentificationChapter 1- Section 2 Pages 8 – 11
40. Let’s get our READ-ON!Mineral IdentificationChapter 1- Section 2 Pages 8 – 11Read and outline Section 2 in your “IN”Helpful hints:Summarize each main sectionHighlight vocabulary words and define themWrite down examples to help you rememberMineral Identification:Chapter 1: Section 2Pages 8-11ColorLuster
41. Bell Work 8/30/13What are the 4 properties of minerals?THINK SINC!! SolidInorganicNaturally occurringCrystalline structure2. What are the 2 groups of minerals? List two examples of each.Silicates – quartz, feldspar, and micaNonsilicates- copper, calcite, fluorite, corundum, gypsum, and galenaOn your desk you should have:Agenda (opened to PRIDE card)Interactive NotebookPencil/Pen
42. Warm-up 9/3/13List the 7 tests used to identify minerals.2. Put a star next to the test you think is the most reliable. Why did you choose that test?ColorLusterStreakCleavage and FractureHardnessDensitySpecial Properties
43. Identifying MineralsGeologists use 7 simple tests to identify minerals.The tests are based on a mineral’s physical and chemical properties.7 testsColorLusterStreakCleavage and FractureHardnessDensitySpecial Properties
44. ColorColor- What does it look like?Least reliable test to determine a mineralMany different minerals have the same colorMinerals can weather and change colorBeryl containing iron (Fe) = blue, yellow, or greenBeryl containing Manganese(Mn) = pink or redBeryl containing Chromium(Cr)= green
45. Warm-up 9/4/131. Minerals are inorganic, what exactly does that mean?2. List 3 other inorganic things:1. 2.3.Inorganic = not alive and never were alive.
46. LusterLuster- The way a surface reflects light.3 types of lusterMetallic- Bright and reflectiveSubmetallic – Dull and reflectiveNon-Metallic- waxy, pearly, earthy, silky, vitreous, plastic
47. StreakStreak- the color of a mineral in powdered form.Rub a mineral across a piece of porcelain called a streak plateGood indicator of a minerals true color because the streak is not affected by air or water.
48. Cleavage and FractureCleavage and Fracture- Describes how a mineral breaksCleavage- the mineral breaks along flat surfacesFracture- the mineral breaks with a rough edge (uneven, curved, irregular)
49. Warm-up 9/5/13What is the difference between cleavage and fracture? Draw an example of each one and label it.CleavageFracture
50. HardnessHardness- a measure of the ability of a mineral to resist scratchingBased on a 1-10 scale called Moh’s Hardness Scale1 = easily scratched10 = resistance to scratchingIf I rubbed Quartz and Calcite together which one would scratch?
51. DensityDensity- the ratio of the mass of a substance to the volume of the substanceMeasured in gm/cm3 One of the best indicators of a mineral’s identity.Pyrite- 5.2 gm/cm3 Gold- 19.3 gm/cm3
52. Special PropertiesFluorescence- Calcite and Fluorite glow under ultraviolet light.Magnetism- Magnetite and Pyrrhotite are natural magnets.Chemical Reaction- Calcite will “fizz” when you put a drop of acid on it.Taste- Halite has a salty taste.Optical Properties- A thin piece of calcite placed over an image will cause a double image.Radioactivity- Minerals that contain radium or uranium can be detected by a Geiger counter.
53. Warm-up 9/6/13Take a look at the mineral Cobalt and write down your observations based on the following tests:1. Color-2. Luster-3. Does it have fracture or cleavage?
54. Warm-up 9/16/12When you are doing a streak test, what is the plate that you rub the mineral against made of?What is the name of the Hardness scale we use to identify minerals?Porcelain Moh’s Hardness Scale
