2.  Classify minerals using common mineral- identification techniques  Explain special properties of minerals  Describe what makes a mineral crystal a gem

3.  How would you know if two minerals were different or the same?  Color  Luster  Streak  Cleavage and Fracture  Hardness  Density

4.  Come in many different color and shades  Same mineral can have a variety of colors  Ex. Quartz is clear when pure  Ex. When there are impurities it can be a variety of colors  Weathering another form that affects color  Pyrite or fools gold turns black

9.  The way the surface reflects  Shiny or dull  Three types of luster  Metallic- shiny or glassy  Submetallic- dull  Nonmetallic-dull

11.  The color of a mineral in powdered form  Streak plate made of unglazed porcelain  Streak not always the same as the color  Not affected by weathering  More reliable then color

12.  Cleavage is the tendency of some minerals to break along flat surfaces  Gem cutters use natural cleavage to remove flaws  Fracture is the tendency of some minerals to break unevenly along curved or irregular surfaces

15.  A mineral’s resistance to being scratched  Moh’s Hardness Scale  Scratch the surface of a mineral with the edge of one of the 10 reference minerals  If the reference mineral scratches the surface of your mineral, it is harder then your mineral

17. Hardness Common material Less that 2.5 mineral that marks paper 2.5 fingernail 3 copper penny 5 steel knife blade 6.5 steel file

18.  Is how much matter there is a given amount of space  Density(g/ cm 3 ) = mass (g) volume (cm 3 )  Water =1 g/cm 3  Specific gravity-ratio of an object’s density to water’s density  Gold=19  19 times more matter in 1 cm 3 of gold than in 1 cm 3 of water

19.  Fluorescence-calcite and fluorite glow under ultraviolet light  Chemical reaction-calcite fizzes when a weak acid is placed on it  Optical properties-thin clear calcite causes a double image

20.  Radioactivity-uranium and radium detected by Geiger counter  Magnetism-natural magnets  Taste-Halite has a salty taste
