1 Science Jeopardy… Minerals

2 Today’s Categories… Mohs Hardness Scale Mineral Characteristics
Vocabulary Mineral Identification Applications

3 Mohs Characteristics Vocab Identify Applications $100 $100 $100 $100 $100 $200 $200 $200 $200 $200 $300 $300 $300 $300 $300 $400 $400 $400 $400 $400 $500 $500 $500 $500 $500

4 Mohs Hardness - $100 What would happen if you rubbed a piece of fluorite against a piece of feldspar? The fluorite would be scratched but the feldspar would not be scratched. Back to Board

5 Mohs Hardness - $200 What would you expect to happen if you rubbed a mineral of hardness 7.5 against a piece of quartz? The mineral would scratch the quartz. Back to Board

6 Mohs Hardness - $300 Which minerals in the table will scratch quartz?
topaz, corundum, and diamond Back to Board

7 Mohs Hardness - $400 An unknown mineral scratches apatite and is scratched by corundum. What can you conclude about this mineral’s hardness? Its hardness is greater than 5 but less than 9. Back to Board

8 Mohs Hardness - $500 List the following minerals in order of decreasing hardness: apatite, calcite, corundum, feldspar, and talc. corundum, feldspar, apatite, calcite, talc Back to Board

9 Characteristics - $100 The atoms of a mineral are arranged in a repeating pattern to form a solid called a(n) ____________________. Crystal Back to Board

10 Characteristics - $200 A mineral is always a(n) ______________ because it has a definite volume and shape. solid Back to Board

11 Characteristics - $300 What are the four characteristics of a mineral?
Naturally occurring, inorganic, definite chemical composition, and crystalline solid Back to Board

12 Characteristics - $400 Minerals can form deep inside Earth’s crust by … a. cleavage and fracture. b. friction along faults. c. crystallization of melted materials. d. evaporation of ancient seas. crystallization of melted materials. Back to Board

13 Characteristics - $500 Minerals may form on Earth’s surface when …
a. magma heats a solution. b. crystallization is delayed. c. solutions evaporate. d. pure metals are present. c. solutions evaporate. Back to Board

14 Vocabulary - $100 Magma that cools slowly below the surface forms _________ crystals. large Back to Board

15 Vocabulary - $200 The faster magma cools, the _____________ that the mineral crystals are that form. smaller Back to Board

16 Vocabulary - $300 DAILY DOUBLE!!!

17 Vocabulary - $400 Two types of ____________________ are metallic and nonmetallic. Luster Back to Board

18 Vocabulary - $500 The splitting of a mineral along flat surfaces is a property called ____________________. cleavage Back to Board

19 Identification - $100 Break mineral apart to see if it splits along flat surfaces. What test is this? Cleavage and Fracture Back to Board

20 Identification - $200 Find mass ÷ volume. What test is this? Density
Back to Board

21 Identification - $300 Observe surface of mineral. What test is this?
Color Back to Board

22 Identification - $400 a. Observe color of powder on unglazed tile.
Perform scratch test What tests are these? a. Streak b. Hardness Back to Board

23 Identification - $500 a. Observe how mineral reflects light.
Observe number and angle of crystal faces. What tests are these? Luster Crystal Shape Back to Board

24 Applications - $100 What is an advantage and a disadvantage to using color to identify a mineral? The color of a mineral is an easily observed property. However, many minerals occur in a variety of colors, so few minerals can be identified based only on their color. Back to Board

25 Applications - $200 About how many minerals have been identified?
4,000 Back to Board

26 Applications - $300 What does a mineral’s streak tell you, and how do you test for it? A mineral’s streak tells the color of the mineral when it is in powder form. The streak test is helpful in telling apart two minerals that are the same color. Even though the minerals look alike, their streak is often different. A mineral is tested for streak by rubbing it against a piece of unglazed tile, or a streak plate. Back to Board

27 Applications - $400 What is the hardest known mineral? Diamond
Back to Board

28 Applications - $500 What is the difference between what mineral properties tell us and what mineral tests tell us? Explain. Mineral properties tell us if something is a mineral or not and mineral tests help us identify minerals. Back to Board

29 Which Statement $100 Gross Margin appears on this statement.
What is the Income Statement? Back to Board

30 Which Statement $200 Gain on Disposal of Equipment appears on this statement. What is the Income Statement? Back to Board

31 Which Statement $300 Accumulated Depreciation appears on this statement. What is the Balance Sheet? Back to Board

32 Which Statement $400 Unrealized Gain on Trading Securities appears on this statement. What is the Income Statement? Back to Board

33 Which Statement $500 Wages Payable to Employees appears on this statement. What is the Balance Sheet? Back to Board

34 Daily Double Specify Your Wager!

35 Vocabulary --- What is an example of a special property that a mineral might have? Fluorescence , Magnetism, Radioactive, Fizzes (reaction to acid), Electrical Properties Back to Board
