Transcript Station 1 - 8

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!
Station 1
• Name A: Talc
• Name B: Quartz
• Hardness Test
Station 2
• General Shape: Cube
• Name: Halite
• Cleavage: the
tendency to break
along flat surfaces
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
Stations 4 - 6
• Station 4: Sandgrains
– Name: Sandstone
• Station 5: fossils
• Station 6: Smells like
matches (sulfur)
Station 7
• Used for scouring
pads
• Name: Pumice
• Extrusive Igneous
Rock
Station 8
• Name: Galena
• Lead is extracted from
galena
Station 9
• B is more densely
packed
• Name
– A: Feldspar
– B: Galena
Station 10
• Used for baby powder
• Used to be called
“soap stone” because
it is slippery
• Name: Talc
Station 11
• Special property:
Magnetic
• Name: Magnetite
Station 12
• One drop of HCl
resulted in the rock
“fizzing”
• Acid Test
• Name: Calcite
Station 13
• Rock is called “fool’s
gold”
• It contains iron
• Name: Pyrite
Station 14
• You saw a double
image of the word
“science”
• Due to double
refraction
• Name: Iceland Spar
(Calcite)
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
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)
Station 19
• (a) Red granite from
Marathon City
• (b) Drilled for blasting
Station 20
• Names: Chert and
Obsidian
• Used to be called
volcanic glass
• Used for arrows and
tools
Station 21
• (a) Coal
• (b) Used for fuel/heat
Stations 22 - 24
• Station 22: Agate
• Station 23: Iron
• Station 24: Animals,
corals, sponge
Stations 25 - 26
• Station 25
– Metal: Aluminum
– Mineral: Bauxite
• 26:
– Used to be used for
chalkboards
– Name: Slate
Stations 27 - 28
• 27: Shark tooth
• 28: Water erosion
Station 29
• From Cave: Dripping
from ceiling
• Name: Stalactite
• (tight to the ceiling)
Station 30 - 33
• 30: Graphite (not
lead), used for pencils
• 31: Chalk
• 32: Sulfur
• 33: Copper ore
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
Station 39
• Station 39:
• It is a sedimentary
rock. We know
this because of the
stratification
(layering) seen in
this rock.
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.
