9. 7 Ways to Identify Minerals: 2. _________: the way a surface reflects light Types of Mineral Luster Metallic: bright, reflective Submetallic: dull, reflective Nonmetallic: vitreous (glassy), silky, resinous (plastic), waxy (greasy), pearly (creamy), earthy (rough) Challenge Question Is luster the best way to identify a mineral? Why or why not? Luster

10. 7 Ways to Identify Minerals: 3. _________: the color of a mineral in powered form A mineral’s _________ can be found by rubbing the mineral against a piece of unglazed porcelain called a __________ _________. The mark left on the streak plate is called the __________. Challenge Question Is the mineral’s streak color the same as the color of the mineral? Why or why not? Streak streak streakplate streak

11. Each pair chooses one of three identification methods we have taken notes on so far, and teach your partner about this way to identify a mineral. Take turns and be good listeners! You have 2 minutes!

12. 7 Ways to Identify Minerals: 4. _____________: different types of minerals break in different ways _________ is the tendency of some minerals to break along smooth, flat surface. _________ is the tendency of some minerals to break unevenly along curved, jagged, or irregular surface. Challenge Question What determines the way minerals break? Cleavage & Fracture Cleavage Fracture
