Subject: Science Grade: 7 Unit #: 2 Title: Ever Changing Earth UNIT OVERVIEW 2.1 c, e, f STAGE ONE: Identify Desired Results Long-Term Transfer Goal At the end of this unit, students will use what they have learned to independently… 2.2 a, b, c, d, e, f, g, h identify natural earth processes and the resulting geologic formations. 3.1 h Enduring Understandings Meaning Essential Questions Students will understand that… Students will consider such questions as… Movement and change in the Earth’s interior causes change in geologic formations. What processes within earth cause geologic activity? Established Goals/Standards Acquisition What knowledge will students learn as part of this unit? Identify and correctly use key terms – convection, tectonic plates, divergent, subduction, mountain, collision, convergence, earthquake, compression, transverse, fault, convection current, Richter’s scale, boundaries, Pangaea Earth’s composition Earth’s crust is broken into plates Earth’s continents once fit together like a puzzle Heat flow and movement within the earth causes crustal movement resulting in earthquakes, volcanic eruption, mountains, and earth basins Scientists analyze earthquake wave data that support the layers within earth Crustal movement causes displacement of the lithosphere What skills will students learn as part of this unit? Making evidence based claims to support the theory of Pangaea and continental drift Reading and interpreting graphs and maps Modeling the layers of the earth and crustal movement Read non-fictional text for information while employing reading strategies. Scientific skills (asking questions, gathering and analyzing data, making predictions, drawing conclusions based on evidence) STAGE TWO: Determine Acceptable Evidence Assessment Evidence East High School, Rochester, NY Based on UbD (ASCD) by G. Wiggins and J. McTighe Subject: Science Grade: 7 Criteria for to assess understanding: (This is used to build the scoring tool.) Self/peer/teacher poster rubric Unit #: 2 Title: Ever Changing Earth Performance Task focused on Transfer: Plate tectonic poster describing the causes and effects of plate movements to show how Earth is changing over time. Other Assessment Evidence: Model- Topographic map Model- Pangaea Stop and Think questions - Layers of the Earth Stop and Think questions – Earthquakes Reflect questions – What causes Earth’s plates to move? Reflect questions - Plate interactions East High School, Rochester, NY Based on UbD (ASCD) by G. Wiggins and J. McTighe Subject: Science Grade: 7 T, M, A (Code for Transfer, Unit #: 2 Title: Ever Changing Earth STAGE THREE: Plan Learning Experiences Meaning Making and Acquisition) Learning Events: Evidence of learning: (formative assessment) A A, M A, M A, M Lesson 1: Introduction to the big question, “What processes within earth cause geologic activity?” Scholars will read pen pal letters from other kids living in different areas around the world. Reflection questions comparing the geography in the letters and in Rochester that look at the geographic differences and similarities. Lesson 2: Scholars begin to consider the structure of Earth by observing photographs of changes in Earth’s surface during geologic events. Scholars also use topography maps to navigate the topography of their region. Bellwork Ticket out the door Graphic organizers Stop and think questions Reflect questions Assessment rubrics Whole group/small group discussions Lesson 3: The concept of a model is introduced as students use a cracked hard-boiled egg to model Earth’s crust. The class is introduced to the idea of making inferences based upon observations. Groups try to infer the contents of two boxes based on observations of size, mass, and sound. Lesson 4: Revisit observations and inferences. Scholars learn that scientists use seismology, volcanoes, and meteorites to learn about the three major parts of the interior of the Earth—the crust, mantle, and core. A, T Lesson 5: Class constructed model of a density column to explain the order of the layers of the earth. Use of graduated cylinders. A, M Lesson 6: Scholars will make a paper model of the layers of the earth. Earth systems reading. Revisit the paper model and discuss where the hydrosphere, lithosphere, etc. would go in the model. A, M Lesson 7: Scholars are introduced to plate boundaries and they use a model to simulate plate interactions. A, M, T Lesson 8: Now that scholars have modeled how plate boundaries move, they look at Pangaea and the evidence surrounding the former theory of continental drift. M, T Lesson 9: Revisit Pangaea in the continuation of the investigation into what causes the plates to move. Now that we know the plates are floating on the mantle, scholars brainstorm what they think is actually moving the plates. They observe a molasses East High School, Rochester, NY Based on UbD (ASCD) by G. Wiggins and J. McTighe Subject: Science Grade: 7 Unit #: 2 Title: Ever Changing Earth model of the mantle. They return to their brainstormed ideas and determine what they want to revise. A, M A, M A, M M Lesson 10: Scholars read about convection, convection currents, and plumes. Stop and think and reflect questions in learning set 4. Lesson 11: Students observe four animations depicting the events when two plates collide and when two plates slide past one another. They then assemble Plate Interactions Flip Books, share them with the class, and reflect on what they have learned about plate boundaries. Lesson 12: Students learn the science of the plate interactions they just observed in the animations through plate interaction stations while they share and discuss their data with the class. Lesson 13: Continuation of the investigation of plate interactions. Scholars look at specific geologic formations that are a result of the interactions such as earthquakes, volcanoes, and mountains. T Lesson 14: Scholars construct a plate tectonic poster describing the causes and effects of plate movements to show how Earth is changing over time. T Lesson 15: Scholars read the, “More to Learn” at the end of the learning set. Groups revise their explanations for the big questions one last time and share with the class.
