ROCKSRock Identification & The Rock Cycle

Engage 1: How many types of rocks are there?

1) In your group, divide the rocks into what you believe are the different types of rocks.

a. How many different types did you come up with?

b. Write down the different characteristics of each group.

Explore 1A: Identifying rocks:

2) The following three locations are popular places to find rocks:

3) If you feel it’s necessary, reorganize your different types of rocks.

4) Pay close attention to the unique features each rock has, including any minerals you see in them. Use the magnifying glass in the kit if necessary. Label your different types of rocks with a fitting name. Fill out the following chart once you have came up with your different types.

Sample #

Where it’s found

Minerals Distinguishing Characteristics

“Type” of rock

lake

Bottom of the Ocean

Beneath Earth’s surface

RiversBeaches

Dirt

Near volcanoes above ground

Mountains

Near volcanoes underground

5) How many different types did you come up with and how are they identified?

Explain 1A: The Different Types of Rocks:

6) Draw one rock from each one of your different types and create a concept sketch: (Use the back if necessary)

7) Classroom discussion.8) How many different types of rocks are there and what are they called?

9) What are the different properties of each type of rock? In other words, what makes each type identifiable?

10)Based on this information, were you close to how many different types of rocks there actually are? Go back and make revisions to your chart with the correct rock type names.

Elaborate 1A: Treasure Hunt Activity

11) Go on a treasure hunt around the school looking for the following rocks and identify them:

Location Rock properties Rock type

Statue in front of office

Countertops in nurses office

Landscaping rock at the flagpole

Landscaping rock next to the picnic tables

Stairs into the main doors

*Homework: Find a rock at home and identify it. Try to come up with a rock name if possible by identifying what type it is then researching online. Bring it in to class tomorrow.

Explore 1B- Sedimentary Rocks:

1) With your partner, organize the sedimentary rock samples into subcategories. Like before, observe the different properties of each rock and come up with a Sedimentary “type” name. Fill out the chart:

Sample # Minerals Distinguishing Characteristics

“Type” of sedimentary rock

Explain 1B: Sedimentary Rock Characteristics:

2) What were the different types of sedimentary rocks that you and your partner came up with? What are the properties of each type?

3) Use the identification chart your teacher handed out and reorganize your data. Fix your chart and add rock names next to each sample along with correct sedimentary rock type.

Elaborate 1B: Concept Sketch:

*Homework: Create a concept sketch showing all three different types of rocks (Sedimentary, Igneous, and Metamorphic). Add details on how to identify sedimentary rocks.

Explore 1C- Igneous Rocks:

1) With your partner, organize the metamorphic rock samples into subcategories. Like before, observe the different properties of each rock and come up with a Igneous “type” name. Fill out the chart:

Sample #

Minerals Distinguishing Characteristics

Texture (fill out during Explain 1C)

“Type” of Igneous rock

Explain 1C: Igneous Rock Characteristics:

1) What were the different types of Igneous rocks that you and your partner came up with? What are the properties of each type?

2) Use the identification chart your teacher handed out and reorganize your data. Pay special attention to the texture. Fix your chart; add rock names next to each sample, and what type of texture the sample has.

Elaborate 1C: Concept Sketch:

*Homework: Add details on how to identify Igneous rocks.

Explore 1D- Metamorphic Rocks:

1) With your partner, organize the sedimentary rock samples into subcategories. Like before, observe the different properties of each rock and come up with a Metamorphic “type” name. Fill out the chart:

Sample # Minerals Distinguishing Characteristics

“Type” of Metamorphic rock

Explain 1D: Metamorphic Rock Characteristics:

1) What were the different types of Metamorphic rocks that you and your partner came up with? What are the properties of each type?

2) Use the identification chart your teacher handed out and reorganize your data. Fix your chart and add rock names next to each sample. Make sure to include whether or not the sample shows foliation in the “distinguishing characteristics” box.

Elaborate 1D: Concept Sketch:

* Add details on how to identify Metamorphic rocks.

***Final concept sketch on all three types of rocks and how to identify them due next class period. ***

Evaluate 1: Quiz on Rock Identification:

1) Classify the following rock: a) What type of rock is it?

Sedimentary Igneous Metamorphic

b) What are the distinguishable characteristics of this rock (Texture, Minerals, Color, Sorting)?

c) Extra Credit: What is this rock’s name?

































10) Classify the following rock:

a) What type of rock is it?




Engage 2: Pop Rocks & Gum Demo:

1) What does the gum represent? What is your teacher “doing” to the gum? Think about what’s happening inside the teacher’s mouth.

2) Now what does the gum represent? What do the pop rocks represent? Now what is happening inside the teacher’s mouth? Think about how your teacher is chewing the pop rocks.

3) After your teacher pulls the gum with pop rocks out of their mouth, what does the gum represent now? Why?

Explore 2A: Dice Activity:

4) Write down what station your group started at. Keep track of the journey that the dice bring you through.

1st Station:

Explain 2A: The “Journey”:

5) How was your journey similar to the journey the gum went through (from the gum and pop rocks demonstration)?

6) What is the journey really called in geological terms?

Elaborate 2A: Virtual Field Trip:

7) Field trip time to the front range of Colorado! With your partner, open the following webpage: http://www.gly.uga.edu/railsback/VFT/VFTFrontRange.html

8) West Denver- Location 1: What two rocks are present? What are their parent rocks?

http://www.gly.uga.edu/railsback/VFT/VFTFrontRange.html

9) Location 2: What type rock is present? How do you know? What kind of features do you see?

10) What does the ridge at location 2 consist of? What’s this ridge called?

11) Explain how this type of ridge is created:

12) West of Colorado Springs- What type of rock is found on the west side of the fault? Explain it’s characteristics.

13) Why does this side of the fault only contain one kind of rock? Explain the process that is happening on the west side of the fault.

Evaluate 2: Quiz:

1) Draw a concept sketch of the rock cycle. Use a specific rock as an example and show the journey the rock goes through. Be sure to include all the processes.
