12.2 Bell RingerTitle new page “Rocks Warm-Ups.” Copy down the following words and put a check mark next to the objects that you would consider a rock.
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.
Sedimentary Cornell Notes
Key Terms Notes
Summary:
What is a rock?
• 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 rock
Sediments
Formation1. Weathering : rocks are broken into little pieces
called sediments2. Erosion: sediments move from one place to
another3. Deposition : sediments settle down
somewhere on earth’s surface and stop moving around
4. Compaction : sediments are squeezed together5. Cementation: sediments start sticking together
and make a sedimentary rock
Characteristics
Flat LayersMixed Particle Size
Fossils
Sedimentary rocks are the only type of rock that can sometimes contain fossils.

Examples• 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
Real Life: The Grand Canyon (Arizona, USA)
Rock Transformation Writing Prompt
Directions: 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. Your story should be at least 4 sentences. Points will be taken off if your story is not written in complete sentences.

Monday Homework
• Finish writing prompt• The Rock Cycle Versatile Worksheet
12.3 Bell Ringer
• Draw a Venn-diagram for rocks and minerals– Include the properties of minerals (5) and
rocks (3)
– Both: Solid, Naturally Occurring, – Mineral: Crystal structure, inorganic, uniform
chemical composition– Rock: May contain organic matter, made of minerals
Metamorphic Cornell Notes
Key Terms Notes
Summary:
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?

• http://www.brainpop.com/science/earthsystem/typesofrocks/
Formation
• Metamorphic rocks are made when a rock changes due to heat or pressure
– Heat from mantle/core, pressure from weight of rocks above
• Formed deep underground
Characteristics
• Bended layers• Squished grains• Very hard and dense
– Because of intense heat and pressure
– Often used for construction (ex: marble)
Bending Layers
Squished Grains
Examples of Metamorphic
Marble: metamorphic rock that comes from metamorphosed limestone or dolomite
Slate: fined grained
metamorphic rock.
Gneiss: medium to course grained metamorphic rock.
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
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 Rock Cornell Notes
Key Terms Notes
Summary:
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?
See if you were right!: BrainPop
• http://www.brainpop.com/science/earthsystem/typesofrocks/
Igneous Formation
• Forms from the cooling of magma or lava– 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 to have large crystal structures and to be coarse and grainy
Stone Mountain
is an example
of Intrusive Igneous!
Stone Mountain

of Intrusive Igneous!
Extrusive Igneous Rock
• Forms outside the Earth from lava• because it is outside it cools rapidly
causing it to be glassy, smooth and have small crystal structures or gas bubbles
Examples of Igneous Rock:
Examples of Igneous Rock:
Extrusive: –Pumice- gray with air bubbles–Obsidian- Shiny, black and smooth
Intrusive: –Granite- large grains

• Create a Venn Diagram for Intrusive and Extrusive Igneous Rock. Should have at least 3 differences for each, and one similarity.
Life of a Rock: Comic Strip Overview
•Goal: Demonstrate an understanding of the rock cycle and the formation of rocks from one type to another.•Role: Comic Strip Creator for Atlanta Journal Constitution Newspaper•Situation: The AJC wants you to design a storybook showing a rock or piece of sediment traveling through rock cycle•Product: Rock Cycle Storyboard•Standard: Students will be able to classify rocks by their process of formation

When finished:•Rock Transformation Writing Prompt
Classifying Sedimentary, Igneous, and Metamorphic Rocks Lab
• Ranger Drake has taken the hikers’ rock back to forest headquarters. He wants to know if it’s an igneous rock like Kimberlite. Igneous, metamorphic, and Sedimentary Rock often look different from each other because they are formed differently.
• Ranger Drake wants to compare the hikers’ rock to samples of igneous, metamorphic, and sedimentary rocks that are stored at headquarters. Unfortunately, the labels have become separated from the rock samples. Can you help him figure out which rock is which?
Classifying Sedimentary, Igneous, and Metamorphic Rocks Lab
• Challenge: How well can you identify different types of rocks?
• Materials (per group): 1 rock sample collected by the hikers, 1 magnifying lens, 1 rock kit
Classifying Sedimentary, Igneous, and Metamorphic
Rocks Lab• Part A (Read directions)
– Fill out data worksheet
• Part B (Read directions): Raise your hand when finished with part A so Ms. Hilgefort can give you your rock sample.– Fill out questions
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
Rock Crayon Lab
Rock Transformation Writing Prompts• When you left your story about being a grain of
sand you were a sedimentary rock. Continue your story by describing your journey to becoming a metamorphic and an igneous rock. Each rock transformation (metamorphic and igneous) should be at least 2 sentences. Points will be taken off if your story is not written in complete sentences.
