Catalyst: • Read pg 45-46
• Can X-Ray dig a hole all the way to China? Is it possible? Why or why not—use what you know about the layers of the Earth to answer.
Is it a Rock?
Copy down the following words and put a check mark next to the objects that you would consider a rock.
Write at least 2-3 sentences explaining your reasoning (what defines a rock?)
What is a rock?
It is:• Naturally formed• Solid• Mixture of one or
more minerals
It is not:• A pile of sand (b/c
the pieces are not packed together)
• A tree because it is a living thing
Sedimentary Rocks
Inquiry: See how much you already know!
• Observe the sedimentary rock on your desk.• Describe what it looks like.• Sedimentary Rock is only one of three types of
rocks, what do you think, from the example in front of you, makes a sedimentary rock sedimentary?

Sedimentary Rock
• Sediments such as dust, mud, rock, sand and shells sweep into oceans and rivers and settle to the bottom
Sedimentary RockOver millions of years these sediments form layers
hundreds of meters thick. The layers press on one another, which causes the sediment to form a kinds of rock
Sediments
Formation of Sedimentary Rocks• It’s a step by step process!
STEP 1. Weathering is when rocks are broken into little pieces called sediments
STEP 2. Erosion is when sediments move from one place to another
STEP 3. Deposition is when sediments settle down somewhere on earth’s surface and stop moving around (think of depositing money in the bank!)
STEP 4. Compaction is when sediments are squeezed together
STEP 5. Cementation is when sediments start sticking together and make a sedimentary rock
Real Life: The Grand Canyon (Arizona, USA)
Flat Layers
Mix of Particle Size
Fossils
Fossils!Since they are formed above the earths surface, sedimentary rocks can sometimes contain fossils. This makes them unique.

Examples of Sedimentary Rocks• Sandstone- as the name
suggests, it is made of grains of sand; often oil is found beneath layers of sandstone
• Shale-also known as “mudstone”; usually found near slowly moving water
• Limestone- made of dead organisms and/or their shells; often found in shallow waters
• Coal- made from the carbon in dead plants; can be burned for energy
Inquiry: See how much you already know!• Observe the metamorphic rock on your desk.• Describe what it looks like.• Metamorphic Rock is only one of three types of
rocks, what do you think, from the example in front of you, makes a metamorphic rock metamorphic?
• How is this rock maybe different from sedimentary?

Metamorphic
• Metamorphic rocks are made when a rock changes due to heat or pressure
Characteristics of Metamorphic Rocks
• Layers that are folded or creased
• Twisted bands
• Very hard and dense– Because of intense heat and
pressure– Often used for construction (ex:
marble)
Bending Layers
Squished Grains
Check for Understanding
• Which of the rocks samples below is probably a metamorphic rock? How do you know?
Sample A – it shows the characteristic folded layers and twisted bands
Exit TicketDirections: Imagine that you are a grain of sand at the
bottom of the river. Write an original story about your life that describes the changes that you have undergo as you become sedimentary rock and then metamorphic rock. Your story should be at least 5 sentences. Points will be taken off if your story is not written in complete sentences.

Catalyst: • Read chapter 10 and 11 of Holes
• Stanley finds a rock with a fish fossil in it, what types of rock are fossils found in?
Igneous Rocks
Inquiry: See how much you already know!
• Observe the igneous rock on the slide.• Describe what it looks like.• Igneous Rock is only one of three types of rocks,
what do you think, from the example in front of you, makes a igneous rock igneous?
• How is it different from sedimentary and metamorphic?

Examples of Metamorphic Igneous Rock:
Marble: metamorphic rock that comes from metamorphosed limestone or dolomite
Slate: fined grained
metamorphic rock.
Gneiss: medium to course grained metamorphic rock.
Real Life: Igneous RockStone Mountain, GA
Igneous Rocks• Igneous rocks forms from the cooling of magma or
lava of a Volcano• Magma is molten (melted) rock inside the volcano• Lava is molten rock outside of the volcano

Play from 45 seconds to about 2 minutes
Intrusive Igneous Rock:
• Forms inside the Earth from magma• because it is inside it cools very slowly
causing it have large crystal structures and to be coarse and grainy
Stone Mountain
is an example
of Intrusive Igneous!

Extrusive Igneous Rock
• Forms outside the Earth from lava• because it is outside it cools rapidly causing it
to glassy, smooth and have small crystal structures or gas bubbles
Examples of Igneous Rock:
Bubbles

Exit Ticket• When you left your story about being a grain of sand you
were a metamorphic rock. Continue your story by describing your journey to becoming an intrusive igneous rock. Also, write an alternative ending of you were to become an extrusive igneous rock. Each story (2) should be at least 4 sentences. Points will be taken off if your story is not written in complete sentences.

Rock Cycle Crayon Lab:Assign Jobs
• Supplies Manager– Gather and return supplies: only one allowed out of group
• Heating Master– Use tongs to heat crayon
• Pressure Master– Use textbook to apply pressure
• Weather/Erosion Master– Break apart and move crayon
*Station Assignments*
Supplies
• 2 crayons• Napkin• Small piece of aluminum foil• Penny• Textbook• Tong• **Large piece of aluminum foil, and hot/cold
water cups will remain at station
Rock Cycle Crayon Lab
• Teacher Demonstration• Important things to remember:
– When putting crayon into hot water, use tongs and only put rock in for about 5 seconds (you are not completely melting it)
– When putting crayon shavings on hot plate, 2 people should use tongs. IMMEDIATELY remove from hot plate when melted. DO NOT LET IT BURN!
– Only 1 group at heating station at a time– Be careful! Any horseplay will results in removal of lab and
alternative assignment
