Mountains of Work – Grade Eight Ohio Standards Connection: Earth and Space Sciences Benchmark E Describe the processes that contribute to the continuous changing of Earth’s surface (e.g., earthquakes, volcanic eruptions, erosion, mountain building and lithospheric plate movements). Indicator 13 Describe how landforms are created through a combination of destructive (e.g., weathering and erosion) and constructive processes (e.g., crustal deformation, volcanic eruptions and deposition of sediment). Lesson Summary: This lesson includes information about the destructive and constructive processes that create landforms. Students will locate information about geologic processes, draw pictures and create a bulletin board. Students will review and use key information in context by reading or presenting a play. The play pits the Wizard of Destruction, representing natural destructive processes, against a soldier trying to protect a house built on the side of a mountain. The postassessment requires students to complete a metaphor or create a comic strip. Estimated Duration: Four hours Commentary: Given the vast array of geologic processes that impact the Earth's lithosphere, student comprehension is a daunting task. This novel lesson encourages student learning through several forms of participation. First, students review geologic processes through the construction of posters and bulletin board displays. Then, students participate in a play that demonstrates how the various geological processes are continuous and concurrent. This lesson was field tested by Ohio teachers. Some of the teacher comments about this lesson follow: "This (play) was a genre that I had never used thinking that the students would complain. They were so excited and were happy to take parts and get to work completing the activities. Some classes chose to make puppets and stay behind a curtain while performing and others wanted to act it out." "The performance of this play for other classes that were studying the same (topic) helped pull the information together and allowed for a very large group discussion about land formations." "The play was challenging and fun." 1 Mountains of Work – Grade Eight Pre-Assessment: Give copies of Attachment A, Pre-Assessment to students to complete. Scoring Guideline: See Attachment B, Pre-Assessment Answers for appropriate responses to the PreAssessment. After checking student performance on the pre-assessment, determine the amount of review necessary before presenting the topic. Post-Assessment: Give copies of Attachment C, Post-Assessment to students. Instruct students to follow the directions on the handout and use the rubric to guide their work You may revise the pre-assessment and use it as the post-assessment instrument. Scoring Guideline: Use the rubric included in Attachment C, Post-Assessment to assess student work. Instructional Procedures: 1. After checking over the pretest for student understanding, have students fill in the correct answers and discuss any terms they may not understand. Tell students to keep their pre-assessments and use them as future reference. 2. Hand out the graphic organizer in Attachment D, The Ups and Downs of Land Formation. Ask students what questions they might be able to answer using the information. Instructional Tip: The information in Attachment D, The Ups and Downs of Land Formation is for student reference. Students are not expected to memorize the lists. It is important to bring to their attention that these processes do not occur in isolation. They are simultaneous and constant. 3. Arrange students into groups of two to five. Assign one of the four main topics from Attachment D, The Ups and Downs of Land Formation (deposition, crustal movement, weathering or erosion) to each group. Have a student in each group choose one of the key components to represent pictorially for a bulletin board or poster display. Allow students to draw, cut out or download a picture. They should include a brief caption identifying the process, agent or result and explaining how it fits into the diagram. For example, if a group is assigned the topic of deposition and one of the students has the key component of waves, that student could use a picture of a sandbar to explain how waves deposit sand. 2 Mountains of Work – Grade Eight 4. Instruct student groups to assemble their displays so they help explain the four main topics from Attachment D, The Ups and Downs of Land Formation. 5. Have students display their work so that all students are able to learn about the various processes impacting the Earth's lithosphere. Instructional Tip: Teachers may want to give students paper, or limit the size of drawings so the organizational chart can be displayed on a bulletin board. The teacher should provide students with texts, articles or the Internet to obtain information needed. This activity is not graded. The objective is to familiarize students with the complexity of the forces shaping the lithosphere. 6. 7. 8. 8. 9. Hand out copies of Attachment E, Mountains of Work Play. This is a play about the processes described in Attachment D, The Ups and Downs of Land Formation. Allow students to choose parts they may want to play and encourage them to choose an appropriate audience for the play. Have students who have chosen not to perform help with scenery, announcements, etc. If more than one student wants the same part, you could have them compete for the part by writing persuasive paragraphs explaining why they feel they would be best. They could then present their paragraphs to the class for a vote. When practicing the play, check for student understanding by having students pick out constructive and destructive processes included in the play. Present the play to your chosen audience. Finish the lesson with the post-assessment. Differentiated Instructional Support: Instruction is differentiated according to learner needs to help all learners either meet the intent of the specified indicator(s) or, if the indicator is already met, to advance beyond the specified indicator(s). The play format provides accessibility to all level of students. Those who do not want speaking parts can help with props and direction. Reading the play aloud encourages all students to take part and does not require any advanced reading skills. Extensions: Have students create models to demonstrate examples of Earth's geologic processes. Possibilities include the following: Use slanted trays with outlets and sand and gravel or diatomaceous earth to create the land. Then use a watering can to create rivers. Make a volcano. Create a glacial outwash by freezing sand and water. Lead students on a walk around the outside of the school building and check for signs of land destruction and construction. 3 Mountains of Work – Grade Eight Have students create a timeline of significant events of the birth and aging of the Appalachian Mountains. Compare it to a timeline of the Rocky Mountains. As an alternate post assessment, have students create their own comic strip showing the constructive and destructive forces. A rubric would need to be developed, but it could be student generated. Homework Options and Home Connections: Encourage parents to help students learn their parts, create costumes and to come to the presentation. Ask students to observe land destruction and construction as they travel with their parents. If possible, students can take photos of these landforms to share with the class. Interdisciplinary Connections: Language Arts: Rather than using a script that was created by the science teacher, work with the language arts teacher to help students in small groups create their own play.

Identifying similarities and differences enhances students’ understanding of, and ability to use, knowledge. This process includes comparing, classifying, creating metaphors and creating analogies and may involve the following: Presenting students with explicit guidance in identifying similarities and differences; Asking students to independently identify similarities and differences; Representing similarities and differences in graphic or symbolic form. Nonlinguistic representations help students think about and recall knowledge. This includes the following: Creating graphic representations (organizers); Making physical models; Generating mental pictures; Drawing pictures and pictographs; Engaging in kinesthetic activity.

List the following words under the correct destructive or constructive force. Destructive Processes Weathering: chemical, mechanical Erosion: wind, water, glacier, gravity, human activity Constructive Processes Deposition: water, glacial, wind Crustal Deformation: compression, tension, plutonic, volcanic II. Use the previous words to describe how the Earth continually breaks down and rebuilds itself. Chemical and mechanical weathering breaks down rock. The actions of wind, water, glaciers, gravity and humans move the Earth to new areas by the process of erosion. Constructive processes include deposition, when the wind, water and glaciers drop soil or rock particles in new areas. Constructive processes also includes crustal uplift caused by compression, tension, plutonic and volcanic forces. 7 Mountains of Work – Grade Eight Attachment C Post-Assessment A metaphor is a way of comparing two things that are not similar. Example: He is a toad. Even though he is not a toad, the comparison helps us understand his looks and personality. Maybe he is like a toad because he is short and squat, a silent watcher with beady eyes, and not attractive. On a separate sheet of paper, create a metaphor for the constructive and destructive processes that create the Earth’s landforms. Explain why it is a good one to choose. You will receive your best grade if you can use show a relationship between all four of the key components that create new landforms and the object or process you chose to use as your metaphor. Scoring Guideline: Student has written a metaphor and explained why it is a good 5 points comparison to the Earth’s constructive and destructive processes. Student has used information from all four processes (deposition, weathering, crustal deformation and erosion), and the metaphor shows a clear relationship between the constructive and destructive forces. Student has written a metaphor and explained why it is a good 4 points comparison to the Earth’s constructive and destructive processes. Student has used only three of the key processes (deposition, weathering, crustal deformation and erosion), or the relationship between the constructive and destructive forces, though present, is could be more clearly stated. Student has written a metaphor and explained why it is a good 3 points comparison to the Earth’s constructive and destructive processes. Student has used only two of the key processes (deposition, weathering, crustal deformation, and erosion), and/or the relationship between the constructive and destructive forces, though present, is somewhat unclear. Student has written a metaphor, but not given a good explanation of the 2 points processes involved. Student has not written a metaphor but only explained the process. Or 1 point the student has written a metaphor, but not shown the relationship to the processes. Example of a 5 point answer The Forces Creating Land Forms Are Giant Recycling Plants Just like a recycling plant, the destructive forces break down the original product. In the recycling plant it might be newspaper or plastic. On the Earth it is rock being broken down by mechanical and chemical weathering. As the material moves through the plant, it is like the earth’s material being moved through erosion. Finally the materials are deposited (deposition on the earth), and reassembled into a new product (paper or plastic object in the recycling plant; layers of sedimentary rock deformed and uplifted to create a new mountain or mountain range). 8 Mountains of Work – Grade Eight Attachment D The Ups and Downs of Land Formation 9 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Setting: Students may decide to create a set, but the play can be performed without scenery. It will be helpful to the audience to have students wear signs indicating their roles if they are not using costumes. The narrator stands to one side. The evil wizards and their minions sit on the opposite side. The mountain (three students) is in the center. The soldier and engineer sit nearby until it is their turn to speak. Then they rise and stand in front of the mountain. Other characters enter from either side. Characters (14 or more): Costumes are optional. Minions should wear signs designating their roles and carry tools. Three students playing the mountain should have bits of paper or packaging peanuts taped to their clothes. Narrator The Wizard of Destruction (WOD) Handsome Soldier Home-Loving General Beautiful Engineer Destruction’s Minions: Weathering: Physical (hammer) Chemical (bottle of acid) Erosion: Wind (balloon) Water (squirt gun) Glaciers (ice cubes) Gravity (weight) Wizard of Construction (WOC) Construction’s Minions: Deposition (bucket to collect debris) Uplift (tire pump or car jack if desired) The mountain (at least three students – one hand touches shoulder of next student) The General’s Home (when it joins the mountain, the two students on the end touch his or her shoulders to form a bond) DRAFT 10 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued Narrator: Once upon a time in a land not so far away, there was a beautiful mountain. It was the most beautiful mountain the world had ever seen, very tall, made of large jagged rocks that stuck up so far that they touched the sky. It was a young mountain, only about ten thousand years old. Nearby, there also lived a handsome soldier (soldier stands and bows), a beautiful engineer (engineer waves) and two angry wizards the Wizard of Destruction (WOD) and the Wizard of Construction (both shake their fists). The Wizard of Destruction who loved to destroy things like beautiful mountains, had a grudge against the handsome soldier. WOD (standing and speaking with a sneer): I have a grudge against that handsome soldier. He stepped on my toes one day at the market. Even though the soldier said “Excuse me,” I will NEVER forget my sore toes. (thoughtfully) The little one was particularly painful. One of these days soon I will get my revenge. Narrator: Sadly enough that day was about to come. Soldier: (stands and looks around). What a beautiful mountain. I like looking at it every day and climbing its steep slopes. I hope it will be here forever. General (entering with person playing his home): Soldier, soldier. I need your help. Soldier (saluting): Yes, sir. General (introducing his home): Soldier, this is my beautiful new mountain home. I am going to put her high on the mountain and retire and live happily ever after. Soldier: Yes, sir. The mountain is a very nice place to have a home. General: Yes, it is soldier. But I must take care of some General business before I move in. Place my home in a safe place and guard her well. If she is safe and happy when I return, I will make you the new General. Soldier: Yes, sir. That should be an easy job for a brave soldier like me. I will guard her well. General: (exits) DRAFT 11 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued Soldier (leading home to the mountain): Come, little house. Here is a beautiful place for you to stay. I will stand guard and let no harm come to you. (Stands in front of the mountain). WOD: Oh, ho. Just what I needed. I love to destroy things piece by piece and scatter the pieces around the world. If I had my way, the Earth would be a flat plane – no mountains, no oceans – nothing but a smooth round ball. Now, I’ll fix that soldier. Weathering and Erosion are you ready? Weathering and Erosion: Yes, we can’t wait to get to work. Weathering: What do you want me to knock apart? Erosion: What do you want me to carry away? WOD: Do you see that big ugly mountain? I want you to round the edges and make the house fall down the slopes. I know it will take some time to do your work, so get started. Weathering: Great! I’ve got my hammer for mechanical weathering (shows hammer) and my acid for chemical weathering (shows plastic bottle labeled acid). Erosion: And I’ve got everything I need to carry away the pieces. Wind (lets a little air out of the balloon), ice (holds an bag of ice), water (watering can) and gravity (weight). Weathering and Erosion (together): Let’s get to work. (They head for the mountain). Narrator: Behind the soldier’s back, the Wizard of Destruction’s minions get to work. Weathering: First, I’ll use my hammer. (Weathering pretends to strike the mountain apart with her hammer). Mountain Rock 1: I am a rock in this mountain. I am very young and very strong. You can’t hurt me. Weathering: You are right. My hammer will not break you. (Aside to the audience) Is it time to use my secret weapon? (Holds up bottle of acid) Mountain: What is that? Weathering: Just a little mild acid. It won’t hurt. (Pretends to pour the acid). DRAFT 12 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued Mountain Rock 1: Wait, I can’t hold on. You’ve broken the bond between us. Mountain Rock 2: Just stay close. Don’t let them take you away. Mountain Rock 3: The mean Wizard of Destruction! Go away Weathering or I’ll call you . . . a lichen. Erosion: Now, it’s time for me to do my work. (Pretends to pour water on the mountain.) Mountain (all the rocks): Help us! Help us, soldier. Mountain Rock 1 (moving away): Goodbye, friends, goodbye. Soldier (turning around): What’s going on here? Get away from here? Weathering and Erosion run away. Mountain Rock 2 (to the home): Little house are you okay? Mountain Rock 3 (to the home): Yes, we are trying to hold you up, but it is hard without Mountain Rock 1 to help us. Home: I am okay. You are still a beautiful mountain and I am happy to be here. I will hold on tight. Narrator: The house looks like it can hold on. But the soldier is worried. He knows he must get help to defeat the Wizard of Destruction and his evil minions Weathering and Erosion. Soldier: Oh, no. Part of the mountain has been broken and moved. I will never become a general this way. I need to get some help. Beautiful Engineer (standing up and looking around): Handsome soldier, what’s wrong? You look very unhappy. Soldier: Weathering and Erosion are trying to destroy this mountain. They have moved some of the rock. The house that the general built may not be safe. What can we do? DRAFT 13 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued Beautiful Engineer: Don’t worry. I am an engineer. I use science to help people solve problems. We will bring in extra rock and use special materials to keep the mountain from falling down. (She brings Rock 1 back, but they do not reconnect). Soldier: You are very beautiful and very clever. When I am a general some day, I will invite your to dinner. Engineer: That sounds very nice, but let’s wait and see what happens. (She walks away). WOD (angrily): Drat it. Drat it. Drat it. Now I’ll never get my revenge. My toes will be sore forever. Weathering: But, Great Wizard of Destruction, we’re not finished. The beautiful engineer cannot defeat us. Erosion: Yes, she saved the house . . . but only for a short time. WOD: Weathering and Erosion, my loyal minions. Together we can even defeat the beautiful engineer. Go back out and do your work. Weathering, you can use ice to break apart the rock. Erosion you can use wind and water to take the pieces away. Narrator: So Weathering and Erosion went back to work. Weathering used acid rain and her friend the lichen to cause tiny cracks to occur in the rock. Then she poured water into the cracks and froze it so they broke apart. (Weathering pretends to pour acid and water and the rocks drop hands and move slightly apart. The house stays in place.) Mountain: Help us. Weathering is breaking us apart. Soldier: I will send for the beautiful engineer. Engineer (rushing in): What’s wrong? Soldier: The rocks in the mountain are being broken apart by chemical and mechanical weathering. Engineer (sadly): I have done everything I can. I can’t save a mountain. Erosion: Now it is my turn. I will use wind and water and glaciers to carry the rock away and wear it down. DRAFT 14 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued (Erosion uses the balloon for wind, pretends to use water from the watering can, and drags ice across one person’s arm. Mountain gets lower and lower. Students are crouching, but house is still standing). General (rushing in): What’s going on? What’s happening to the mountain? Is my house okay? Soldier: No, sir. I am very sorry. Weathering and erosion are rounding out the mountain – but your house is still standing. WOD (sneering): Not for long. Finally, I will have my revenge. You will never be a general. Erosion, bring out the gravity. Beautiful engineer: Oh, no. Not the gravity. House: I have tried to stay here on the hill. It has been a long battle with Weather and Erosion. Goodbye, General. Don’t build your next house on the side of a mountain. (Erosion hands her the weight. The house takes it and sits down behind what is left of the mountain. The students playing the mountain should also be seated at this time.) General: My beautiful house is gone. Soldier: I am so sorry, General. Engineer: I did everything I could. Narrator: Everyone except the Wizard of Destruction is very sad. He likes the rounded hills where the mountains once stood and he’s glad the house is gone and his toes feel much better. But just when the mountains have almost completely disappeared, there is a puff of smoke and a crash that sounds like thunder. The Wizard of Destruction’s twin brother, the Wizard of Construction, appears. (Engineer, General, and Soldier hold their ears.) General: What is that terrible noise? Engineer: It’s the Wizard of Construction, but he’s too late. Everything is gone. DRAFT 15 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued WOC: It is never too late for the Earth. But I can see you are all very young and very afraid. First I will let you sleep for a few thousand years while I rebuild. (He waves his hands and the engineer, general and soldier fall fast asleep). WOC: Dear Brother, what have you been up to? WOD: Just the usual. A little weathering here. A little erosion there. You know. (Weathering and erosion cower behind him). WOC: Well, what’s done is done. Let me see what my friends deposition and uplift can do to bring back a mountain or two. Deposition. You gather up any materials you find and drop them together in a pile. Deposition (to the audience): That’s me, Deposition. Gravity may help erosion, but it helps me more. I’m Erosion’s worst enemy. He can’t carry that soil or dust forever. Sooner or later he drops the heavy pieces, and then the pieces that are a little bit lighter, and finally the lightest of all. The pieces fill in all the low areas, evening things out. (Deposition joins the mountain back together. It continues to stay low). WOC: Nice job, deposition. Now we’ll wait until those pieces are nice and firmly cemented together. Let’s see-one thousand years, two thousand years, three thousand – okay. Uplift, it’s your turn. Uplift (to the audience): Hi, I’m called Uplift. I do my work by deforming the crust. I push it and pull it, stretch it and break it. I work with some guys you’ll meet at another time to recreate the mountains and plateaus after weathering, erosion, and deposition have done their work. Now watch this. (Uplift uses his/her hands (or the tire pump or jack) to raise the mountains. The students stand up.) Uplift (Turns to the audience, bows, and smiles.): Pretty cool. WOC: Okay, okay. So you are wonderful. Doesn’t mean you’ll get a raise, though. Let’s see. What am I forgetting? Deposition (pointing to the sleepers): Don’t forget them. WOC: Oh, yeah. (Snaps his fingers). Wake up. DRAFT 16 Mountains of Work – Grade Eight Attachment E Mountains of Work Play Continued (General, engineer and soldier wake up). Soldier: Wow, what a great nap. I feel like I’ve been asleep forever. Gosh, look at that beautiful mountain. Engineer (yawning): Yes, that is a beautiful mountain. General (yawning): That mountain? What a view? What a great place to build a house! WOD (rubbing his hands together): Here we go again. WOC: This would be the perfect place for us all to say “The End,” but we know it never ends. The Wizards of Destruction and Construction will always be at work. WOD: Yep, look for us today on your way home. WOC: And look for our friends Weathering, Erosion and Deposition. Check your sidewalk and home for a mini view of our friend Uplift. Narrator: Well, they may go on forever, but our time is up. Thanks for listening to our story. (Characters take a bow.) DRAFT 17
