1. Introduction to Minerals and Rocks During this presentation, record the names of minerals and rocks in a DIFFERENT color! If your answer is wrong, change it!

2. Station 1 Name A: Talc Name B: Quartz Hardness Test

3. Station 2 General Shape: Cube Name: Halite Cleavage: the tendency to break along flat surfaces

4. Station 3 Petrified Wood Fallen wood buried in mud, ash, etc. Oxygen deprived and cannot decay Organic materials break down and create void Void gets filled with minerals and they crystallize

5. Stations 4 - 6 Station 4: Sandgrains –Name: Sandstone Station 5: fossils Station 6: Smells like matches (sulfur)

6. Station 7 Used for scouring pads Name: Pumice Extrusive Igneous Rock

7. Station 8 Name: Galena Lead is extracted from galena

8. Station 9 B is more densely packed Name –A: Feldspar –B: Galena

9. Station 10 Used for baby powder Used to be called “soap stone” because it is slippery Name: Talc

10. Station 11 Special property: Magnetic Name: Magnetite

11. Station 12 One drop of HCl resulted in the rock “fizzing” Acid Test Name: Calcite

12. Station 13 Rock is called “fool’s gold” It contains iron Name: Pyrite

13. Station 14 You saw a double image of the word “science” Due to double refraction Name: Iceland Spar (Calcite)

14. Stations 15 & 16 Station 15: Crystals formed with air pocket then solidified –Name: Geode Station 16: Clams in the mud caused the holes –Name: Mudstone

15. Stations 17 & 18 Station 17: Gold ore taken from Homestake Mine in South Dakota Station 18: Copper, but turns green when it reacts with oxygen (i.e. Statue of Liberty)

16. Station 19 (a) Red granite from Marathon City (b) Drilled for blasting

17. Station 20 Names: Chert and Obsidian Used to be called volcanic glass Used for arrows and tools

18. Station 21 (a) Coal (b) Used for fuel/heat

19. Stations 22 - 24 Station 22: Agate Station 23: Iron Station 24: Animals, corals, sponge

20. Stations 25 - 26 Station 25 –Metal: Aluminum –Mineral: Bauxite 26: –Used to be used for chalkboards –Name: Slate

21. Stations 27 - 28 27: Shark tooth 28: Water erosion

22. Station 29 From Cave: Dripping from ceiling Name: Stalactite (tight to the ceiling)

23. Station 30 - 33 30: Graphite (not lead), used for pencils 31: Chalk 32: Sulfur 33: Copper ore

24. Stations 34 - 38 34: Rocks, not bones. 35: Formed with gravel, pebbles –Name: Conglomerate 36: Rocks rubbed by water 37 Found in a cave –Name: Stalagmites –(might grow up to the ceiling) 38: Holes are probably caused by clams in mud –Name: Mudstone

25. Station 39 Station 39: It is a sedimentary rock. We know this because of the stratification (layering) seen in this rock.

26. Station 40 It floats because it is less dense than water. When it was formed, gas was trapped inside while the magma and other pyroclastic materials solidified quickly.
