3 RAHWAY PUBLIC SCHOOLS CURRICULUM UNIT OVERVIEW Content Area: Science Unit Title: Earth History - Investigation 1: Earth is Rock Target Course/Grade Level: 8 th grade Unit Summary: The unit Earth History focuses on having students practice on their inferential thinking skills. They can begin to grapple with the Earth s processes and systems that have operated over geological time. Students should make observations and do investigations that involve constructing and using conceptual models. They should generate questions for investigations, which may lead to new questions. Through their study of Earth History, students should become more confident in their ability to ask good questions and to recognize and use evidence from the rocks to come up with explanations of past environments. The purpose of Earth is Rock is to introduce students to the study of both rock and land formations that make up the Earth s Crust. Students will begin developing awareness about the complexity of Earth s crust and how geologist studies it.

Why do there appear to be stripes on the walls of the Grand Canyon? How are the rocks from the two Grand Canyon sites related to each other? Knowledge and Skills Students will know Earth s surface has a variety of different landforms and water features. Every place on Earth s surface has a unique geological story. Rocks hold the clues to the story of a place. Limestone, sandstone, and shale are rocks found in the Grand Canyon that can be identified by their characteristics that can be identified by their characteristics. Students will be able to Make and record observations of landforms on Earth s surface and some of the rocks that compose them. Analyze rock samples from different sites to make rock correlations. EVIDENCE OF LEARNING Assessment What evidence will be collected and deemed acceptable to show that students truly understand? Students note a number of different landforms at various locations. Students can differentiate between landforms (such as a mountain) and artifacts of digital images (such as a straight line indicating two images have been patched together). Students generate meaningful observations or questions related to the topics of landforms or geology. Students understand that the stripes on are actually the edges of different types of rocks, stacked in layers on top of each other. Students do not think that the rocks are painted or otherwise marked superficially by the stripes. Students understand that the layers of rocks continue in the ground beyond what is seen. Students can create a model of rock layers and correlate two sites by aligning similar rocks in horizontal layers. Students make inferences about how the rocks might be layered underground and indicate this by drawing horizontal lines between two sites. Students can represent the drop in elevation of the Colorado River as it flows from east to west by drawing a slanted line. Students perform well on Mid-Summative exam 1. Homework.

MS-ESS2-2: Construct an explanation based on evidence for how geoscience processes have changed Earth s surface at varying time and spatial scales.

7 Science and Engineering Practices: Asking questions Developing and using models Planning and carrying out investigations Analyzing and interpreting data Using mathematics and computational thinking Constructing explanations Engaging in argument from evidence Obtaining, evaluating, and communicating information Disciplinary Core Ideas: ESS2.A: Earth s Materials and Systems: All Earth processes are the result of energy flowing and matter cycling within and among the planets systems. This energy is derived from the sun and Earth s hot interior. The energy that flows and matter that cycles produce chemical and physical changes in Earth s materials and living organisms. (MS-ESS2-1) ESS2.C: The Roles of Water in Earth s Surface Processes: Water s movements-both on the land and underground- causes weathering and erosion, which change the lands surface features and create underground formations. (MS-ESS1-4) Cross Cutting Concepts Systems and System Models: Models can be used to represent systems and their interactions. Scale, Proportion, and Quantity: Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or goo small. Patterns: Science assumes that objects and events in natural systems occur in consistent patterns that are understandable through measurement and observation. Stability and Change: Explanations of stability and change in natural or designed systems can be constructed by examining the changes over time and processes at different scales, including the atomic scale. Unit Understandings Students will understand that Particles of earth material can be categorized and sorted by size: Clay, silt, sand, gravel, pebble, cobble, and boulder. Rock can be weathered into sediments by a number of processes, including frost wedging, abrasion, chemical dissolution, and root wedging. Most landforms are shaped by slow, persistent processes that proceed over the course of millions of years: weathering, erosion, and deposition. Most sediments move downhill until they are deposited in a basin. Sediments that do not form rock can become widely distributed over Earth s surface as soil. Unit Essential Questions How big are rocks? How do earth material get sored in nature? Which came first, the sand or the sandstone? How is soil related to rocks? Knowledge and Skills Students will know Particles of earth material can be categorized and sorted by size: Clay, silt, sand, gravel, pebble, cobble, and boulder. Rock can be weathered into sediments by a number of processes, including frost wedging, abrasion, chemical dissolution, and root wedging. Most landforms are shaped by slow, persistent processes that proceed over the course of millions of years: weathering, erosion, and deposition. Most sediments move downhill until they are deposited in a basin. Sediments that do not form rock can become widely distributed over Earth s surface as soil. Students will be able to Sort earth materials by size, using different methods. Use models to represent, study, and manipulate Earth Processes. EVIDENCE OF LEARNING Assessment What evidence will be collected and deemed acceptable to show that students truly understand? Students use a ruler correctly by lining up the rock with the 0 mm marker. Students correctly round measurements that fall between millimeter marks. Students understand how to use the Wentworth scale to categorize rocks based on their measurements. Students can correctly identify landforms.

8 Students use quantitative data and diagrams to record data. Students understand that the Colorado River erodes earth material from the Grand Canyon and deposits the material along the rivers path and at the end of the river, including sandbars and in lake mead. Students understand that the Colorado Plateau formed before the Colorado River began to weather it and erode it away. Students understand that beach sand is more rounded and the homemade sand is more angular. Students make other valid comparisons between the sand samples, including particle size and source material. Students will consider that weathering over an extremely long period of time will wear away at rock possibly creating a canyon. Students will consider that physical and chemical weathering may have created the Grand Canyon. Students will consider that weathering is still occurring at the Grand Canyon today. Students explain that sand is broken-down bits of rock. Students explain that rocks are broken off from even larger rocks, which themselves were once parts of mountains or bedrock. Students make the distinction that earth materials are found in different sizes, but that they are all forms of rock. Students explain the processes of weathering and erosion that would create sand and bring it to a beach. Students perform well on Mid-Summative exam 2. Homework.

Through their study of Earth History, students should become more confident in their ability to ask good questions and to recognize and use evidence from the rocks to come up with explanations of past environments. The purpose of Deposition is to have students closely look at the processes by which bedrock is weathered and eroded and how sediments are deposited in basins. Students will see that under favorable conditions these sediments can turn into sedimentary rock. Students can then see how evidence from sedimentary rocks can provide clues to Earth s history.

Unit Understandings Students will understand that Sediments deposited by water usually form flat, horizontal layers. Sediments turn into solid rock (such as sandstone, shale, and limestone) through the process of lithification, which involves compaction, cementation, and dissolution. Sandstone is a sedimentary rock formed when particles of sand are cemented together. Shale is a sedimentary rock formed when clay and silt particles are compacted and cemented together. Limestone is a sedimentary rock composed mainly of calcium carbonate, deposited in oceanic basins by physical, chemical, and biological processes. The relative ages of sedimentary rock can be determined by the sequence of layers. Lower layers are older tan higher layers. The processes we observe today, such as weathering, erosion, and deposition, probably acted in the same way millions of years ago, producing sedimentary rocks. Unit Essential Questions What happens to sediments that get deposited in basins? How does limestone form? What do sedimentary rock layers reveal about ancient environments? Knowledge and Skills Students will know Sediments deposited by water usually form flat, horizontal layers. Sediments turn into solid rock (such as sandstone, shale, and limestone) through the process of lithification, which involves compaction, cementation, and dissolution. The relative ages of sedimentary rock can be determined by the sequence of layers. Lower layers are older tan higher layers. The processes we observe today, such as weathering, erosion, and deposition, probably acted in the same way millions of years ago, producing sedimentary rocks. Students will be able to Identify the components of sandstone, shale, limestone, and soil. Infer change in environments through the interpretation of a sequence of sedimentary rock layers.

11 EVIDENCE OF LEARNING Assessment What evidence will be collected and deemed acceptable to show that students truly understand? Students understand that sand is just small rocks formed by rocks breaking into pieces. Students explain that sand can flow into a basin and become sandstone by a process that involves compaction and introduction of a cement by groundwater. Students mention that sandstone can again be broken into bits of sand by weathering. Students make a connection between the precipitate forming in the limewater reaction and the sediment that could form limestone. Students explain that the area that is now the Colorado Plateau used to be in a basin and the sediments were deposited in the basin over a very long time. Students suggest that the environment changed over time. Students describe that each environment accumulated different sediments. Students suggest that different layers of rocks formed, depending on the kinds of sediments that were deposited, which in turn depended on the environment.

Scale, Proportion, and Quantity: Time, space, and energy phenomena can be observed at various scales using models to study systems that are too large or goo small. Patterns: Science assumes that objects and events in natural systems occur in consistent patterns that are understandable through measurement and observation. Unit Understandings Students will understand that A fossil is any remains, trace, or imprint of a plant or animal that was preserved in Earth s crust during ancient times. The fossil record represents what we know about ancient life and is constantly refined as new fossil evidence is discovered. Geological time extends from Earth s origin to the present. Earth s history is measured in millions and billions of years. Index fossils allow rock layers to be correlated by age over vast distances. Unit Essential Questions How do fossils get in rocks? How old are fossils? How do we categorize extremely long periods of time? When did the Gran Canyon rocks form? Knowledge and Skills Students will know A fossil is any remains, trace, or imprint of a plant or animal that was preserved in Earth s crust during ancient times. The fossil record represents what we know about ancient life and is constantly refined as new fossil evidence is discovered. Geological time extends from Earth s origin to the present. Earth s history is measured in millions and billions of years. Index fossils allow rock layers to be correlated by age over vast distances. Students will be able to Construct a time line of geological events and ancient life. Infer ancient environments based on rock and fossil evidence. Describe how rocks can be given a relative age based on their relationship to other rocks.

14 EVIDENCE OF LEARNING Assessment What evidence will be collected and deemed acceptable to show that students truly understand? Students explain that the remnants of organisms that form fossils are embedded in sediments before the rocks form. Students explain that bodies of organisms become fossilized over long periods of time. Students indicate that fossils are not just bodies of animals, but can also be parts of plants or imprints of organisms. Students work according to the Law of Superposition. Students understand that the time line represents the history of life on Earth from the time of its formation. Students identify that human history is a tiny, recent piece of the vast history of life on Earth, and of the history of Earth itself. Students understand that not all fossils are index fossils, and that only those identified as index fossils should be used to correlate the rock layers. Students infer the correct relationship between sites, based on the index-fossil and layer correlation. Students perform well on Mid-Summative exam 4. Homework.

18 RAHWAY PUBLIC SCHOOLS CURRICULUM UNIT OVERVIEW Content Area: Science Unit Title: Earth History - Investigation 6: Volcanoes and Earthquakes Target Course/Grade Level: 8 th grade Unit Summary: The unit Earth History focuses on having students practice on their inferential thinking skills. They can begin to grapple with the Earth s processes and systems that have operated over geological time. Students should make observations and do investigations that involve constructing and using conceptual models. They should generate questions for investigations, which may lead to new questions. Through their study of Earth History, students should become more confident in their ability to ask good questions and to recognize and use evidence from the rocks to come up with explanations of past environments. The purpose of Volcanoes and Earthquakes is to provide students with the opportunity to discover a pattern of geological activity. Subduction, convection, and the theory of crustal plate tectonics are introduced to explain continental drift, plate boundary interactions, and the patters of volcanoes and earthquakes.

Unit Understandings Students will understand that Volcanoes and earthquakes occur along plate boundaries. Earth s crust and solid upper mantle make up Earth s plates. Plates can be the size of continents or larger or smaller. Earth s plates float on top of the layer of viscous, semisolid earth material below, the asthenosphere. The asthenosphere is a heated, semisolid, semifluid material that flows due to convection currents. Plate movements result in plate boundary interactions that produce volcanoes, earthquakes, and continental drift. Unit Essential Questions Where do volcanoes occur on Earth? Where do earthquakes occur on Earth? Why do volcanoes and earthquakes occur where they do? What causes plates to move?
