1 Title: Rock Cycle Comic Strip Author: Ashley Packard Subject Area: Geology Grade: 8 Description of Lesson: This lesson is designed to help the students understand how the rock cycle works. They will play the role of a rock that goes through a journey of change as it moves through the rock cycle. As the students physically move through the various stations, the rocks will go through a variety of situations and locations. It is up to the students to use their knowledge of the rock cycle and how rocks change to figure out how they (as that specific rock) will be affected. The lesson allows the students to apply the vocabulary words that they have been learning. Length of Lesson: One 45-minute class period to complete the Journey through the Rock Cycle worksheet using the 8 stations and to get the students started on their comic strip. One 45-minute class period work time on the comic strip. Student Objectives: Using specific examples, students will be able to explain how rocks change as they go through the rock cycle. Using specific examples and proper vocabulary, students will be able to draw and label the rock cycle. Students will be able to explain how each of the three rock types is made (sedimentary, igneous, and metamorphic). Materials: Class set of copies of Journey through the Rock Cycle Worksheet Event Sheet (cut into strips and placed into the proper station s envelope) 8 stations (land, volcano, mountain, river, ocean, atmosphere, subterranean, mantle) taped to the walls around the room (each with an envelope for the cut-out event strips) Rock Cycle Comic Strip Requirements Sheet and Scoring Rubric Class notes or textbook with material covering the rock cycle Markers, crayons, colored pencils to use on the comic strip Procedure: Set Up: Set up 8 stations for stops along the Rock Cycle. Label a sheet of paper to identify each station for students. The stations are: Mountain River Atmosphere Mantle Ocean Volcano Land Subterranean For each station cut the associated event sheet into strips and place them inside the container. Activity: 1. Explain to students that they are a piece of rock, and they are about to take a journey.

2 2. Distribute the Journey through the Rock Cycle to each student. 3. Divide students equally between the eight stations. 4. Tell the students to begin drawing slips of paper. 5. On the Journey through the Rock Cycle sheet, they will record what happens to them (as the rock). 6. They will move to the station the slip of paper tells them to. Once they have the information from that slip of paper, they must put the slip of paper back into that specific envelope for the next student. 7. The students will continue this process until they (as the rock) have gone through twelve different changes. 8. When all students are done, pass out and discuss the comic strip requirements sheet and scoring rubric. Their challenge is to create a cartoon strip or story about their journey through the rock cycle. Students can use their textbook or class materials (notes and assignments) to help them complete this task. The students need to identify what kind of rock they were at each step of their journey. Scientific Explanation: The rock cycle is the continuous cycle of change that rocks go through. These processes can occur extremely quickly or may take thousands or up to millions of years. The rock cycle displays how sedimentary rocks can be changed into igneous or metamorphic rocks and vice versa. For example, the rock cycle shows how sedimentary rocks can be broken down into sediments by weathering and erosion. By cementation and lithification, these sediments can be changed into sedimentary rocks. Through heat and pressure, sedimentary rocks can be converted into metamorphic rocks. Through melting, sedimentary rocks can be modified into igneous rocks. Metamorphic rocks can be melted into magma, or they can be broken down by weathering and erosion into sediments. Magma can be cooled and crystallized into igneous rock. Through heat and pressure, igneous rocks can be changed into metamorphic rocks. Through weathering and erosion, igneous rocks can be broken down into sediments. Igneous rocks can be melted into magma. sedimentary rocks - rocks formed from sediments pressed together igneous rocks - rocks formed by cooling molten rock metamorphic rocks - rocks formed by transforming existing rocks by heat and pressure into different rocks sediments - material that is broken down into smaller pieces by weathering and erosion (sizes include boulders, gravel, sand, silt, mud, clay) weathering - breaking down of rocks, soil, and minerals through mechanical or chemical means. Mechanical weathering occurs when heat, water, ice, and/or pressure changes rocks. Chemical weathering occurs when chemicals change rocks. erosion - moving sediments, soil, rocks, etc. by wind, water, or ice. cementation - sediments are stuck or cemented together to form new rocks. lithification - the process where sediments are compacted under pressure, get rid of fluids, and gradually become solid rock. magma - liquid rock found beneath the surface of the Earth. Assessment: Students will be required to complete The Journey through the Rock Cycle worksheet. Following the requirements on the Rock Cycle Comic Strip instruction sheet, the students will design a comic strip that summarizes their journey as a rock through the rock cycle stations. The students will be assessed on the accuracy and completeness of their rock cycle comic strip. The comic strip will be graded according to the attached scoring rubric.

3 Missouri and Kansas Standards Addressed: Kansas Science Standards: Grades 5-7 Standard 4, Benchmark 1: The student will understand that the structure of the earth system is continuously changing due to earth's physical and chemical processes. (Indicators 1 and 2) Grades 8-12 Standard 4, Benchmark 1: The student will develop an understanding of the sources of energy that power the subsystems and cycles of the dynamic earth: the geosphere, hydrosphere, atmosphere and biosphere. (Indicator 1) Missouri Science Standards (GLEs): 8 th grade Strand 5.2, Concept C a. Explain how heating and cooling in the mantle layer leads to the formation of metamorphic rocks and some igneous rocks (DOK 2) Strand 5.2, Concept C b. Make inferences about the formation of igneous and metamorphic rocks from their physical properties (e.g., crystal size indicates rate of cooling, air pockets or glassy texture indicate volcanic activity) (DOK 2) Strand 5.2, Concept C c. Explain and diagram the external and internal processes of the rock cycle (e.g., weathering and erosion, sedimentation, compaction, heating, recrystallization, resurfacing due to forces that drive plate motion) (DOK 2)

4 Journey through the Rock Cycle Name On this sheet, record what happens to you as a rock as you go through the rock cycle. Describe your experiences at each station, describe what processes changed you, and describe what type of rock you were transformed into. At each station, draw a slip of paper from the envelope and record what happens. Return the slip of paper to the envelope and move to the station that it told you to. Specific Rock Type you will begin this journey as: (Drawing below) (1) I began my adventure at. (2) The first thing that happened was, then I went to. (3) The next thing that happened was, (4) The next thing that happened was, (5) The next thing that happened was, (6) The next thing that happened was, (7) The next thing that happened was, (8) The next thing that happened was, (9) The next thing that happened was, (10) The next thing that happened was, (11) The next thing that happened was, (12) The next thing that happened was,

8 Rock Cycle Comic Strip You will be making a comic strip of your journey as a rock through the rock cycle. On the front side of the activity sheet Journey through the Rock Cycle, draw, color, and label a picture of the rock type and specific rock that you started out as. You can choose to be whatever one you want. (If you are feeling creative, you can name yourself.) Put the comic strip on the BACK of your activity sheet from Journey through the Rock Cycle. Fold the paper, so it will have six boxes. Using the information on the front of your activity sheet, you will choose 6 different locations on your rock cycle trip. If at all possible, do not repeat locations. As long as the order of the boxes makes sense, it can be any six locations. For each box, write down the location where this takes place and what it said on the strip of paper that you got out of the envelope in class. Then, draw the location (as you picture it) and what was happening to you (the rock) there. For each box, tell what rock type you would be by the end of that location. For example, if you are broken down into little pieces, then you would be sediments that make up a sedimentary rock. If you are heated into liquid rock, then you would be magma or lava. If you are a rock that is changed using heat and pressure, then you would be changed into a metamorphic rock. Number each box in order (#1-6) as they occur. Add color to your picture and be creative!!! Location: What happens to the rock: When finished, what rock are you now: # of box Colored drawing of location and what is happening to the rock
