Student Review Guide Geoscience Explorations Semester B Examination 2013-2014 (Honors and On-Level) Montgomery County Public Schools Test Description Length: 2 hours Format: Students will select three (3) of four (4) writing prompts and complete a brief constructed response for each. (Honors exam requires students to answer one assigned wring prompt, and select two (2) more of three (3) writing prompts). Teacher Guidance on Use of Sample Writing Prompts Sample writing prompts are provided to encourage appropriate student collaboration and review of concepts in preparation for the exam. Although the sample writing prompts address the same concepts as the actual exam prompts, they are not identical to the exam prompts. Each actual exam prompt includes one of the NGSS Science and Engineering Practices. For example, data is provided within one of the exam prompts, and students are asked to analyze and interpret the data as part of their BCR response. What is the purpose of the sample writing prompts? In problem-based learning, students sometimes have difficulty applying learning to new situations since they work with one scenario/RFP throughout the unit. The writing prompts provide alternative real world examples related to the same content indicators. The final exam prompts require students to apply their learning to a new scenario. The sample writing prompts within this student review are designed to serve as preparation for the final exam. Although these writing prompts are similar to the types of questions that will be asked on the final exam, they are not representative of the amount of information asked per prompt. How should teachers use the sample writing prompts? The sample writing prompts provided in this student review are not identical to the actual exam prompts. For this reason, teachers may help students to construct responses to sample writing prompts. The sample prompts may be used as a formative assessment, either to grade students on their progress or as tool for adjusting instruction, or as an end of unit summative assessment. When teachers grade student work on sample writing prompts, they should assess the understanding demonstrated by the student. Although students need to fully, clearly and accurately express their ideas, they should not be assessed on grammar or punctuation. Students should be encouraged to express ideas in multiple ways including pictures, graphs, web diagrams, tables, etc. Geoscience Explorations Student Review Semester B 2013-2014 When should teachers use sample writing prompts? The sample writing prompts are not designed to go with any particular day of instruction, but rather are supplemental for teachers’ choice to use as and when appropriate. It is not intended that every writing prompt and assessment probe is used. It is up to the teacher’s discretion on when and how to use these resources. Some examples of using the prompts include using them for group work at the end of a unit, for homework after project presentations, or for classwork during final exam review. What are some ways to support students to fully demonstrate their learning on these types of assessment items? It is important to help students to understand how to answer the types of questions included within sample writing prompts. There are many ways to support students in this process, including: - Question analysis techniques, such as highlighting or underlining Teacher think-aloud while reading prompts Use of graphic organizers to organize ideas prior to writing Pre-writing brainstorming discourse Discourse between drafts for ideas on enhancement Peer reviewing using plus/delta feedback Multiple drafts based on peer and teacher feedback Use of graphics to support answers Sample Writing Prompts Sample Writing Prompt #1: Scientific Investigation The substances that are dissolved in seawater came from the weathering and erosion of continental rocks. Use your knowledge of water and Earth systems to design an investigation to test how long it takes for water to dissolve rock material. Sample Writing Prompt #2: Seafloor Autonomous underwater gliders explore and map seafloor features like mid-ocean ridges and the abyssal plain. Develop (draw) a model of the ocean floor that explains the formation of at least three major seafloor features by plate tectonic processes. Sample Writing Prompt #3: Coral Reefs Human activity has had a major effect on coral reefs around the world: large areas of reef systems are no longer covered by living organisms. Construct an explanation of the impact of human activity on coral reefs that includes the geosphere, atmosphere and oceans. Sample Writing Prompt #4: Chesapeake Bay Dead Zones Some regions in the Chesapeake Bay are characterized by dead zones: the bottom environment is so depleted of oxygen that marine life cannot survive. Prepare an argument from evidence to support regulations on land use in order to reduce dead zones in the Bay. Geoscience Explorations Student Review Semester B 2013-2014 NGSS Performance Expectations and Disciplinary Core Ideas (Each writing prompt is aligned to NGSS Performance Expectations. Students earn credit by demonstrating their understanding of Disciplinary Core Ideas in the context of Science and Engineering Practices, and applying Cross-Cutting Concepts within their responses). Unit 3: Marine Geoscience HS-ESS1-5 Evaluate evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics to explain the ages of crustal rocks. Disciplinary Core Ideas: ESS1.C: The History of Planet Earth Continental rocks, which can be older than 4 billion years, are generally much older than the rocks of the ocean floor, which are less than 200 million years old. (HS-ESS1-5) ESS2.B: Plate Tectonics and Large-Scale System Interactions Plate tectonics is the unifying theory that explains the past and current movements of the rocks at Earth’s surface and provides a framework for understanding its geologic history. (ESS2.B Grade 8 GBE) (secondary to HS-ESS1-5) HS-ESS2-1 Develop a model to illustrate how Earth’s internal and surface processes operate at different spatial and temporal scales to form continental and ocean-floor features. Disciplinary Core Ideas: ESS2.A: Earth Materials and Systems Earth’s systems, being dynamic and interacting, cause feedback effects that can increase or decrease the original changes. (HS-ESS2-1), (HS-ESS2-2) ESS2.B: Plate Tectonics and Large-Scale System Interactions Plate tectonics is the unifying theory that explains the past and current movements of the rocks at Earth’s surface and provides a framework for understanding its geologic history. Plate movements are responsible for most continental and ocean-floor features and for the distribution of most rocks and minerals within Earth’s crust. (ESS2.B Grade 8 GBE) (HS-ESS2-1) HS-EES2-4 Use a model to describe how variations in the flow of energy into and out of Earth’s systems result in changes in climate. Disciplinary Core Ideas: ESS1.B: Earth and the Solar System Cyclical changes in the shape of Earth’s orbit around the sun, together with changes in the tilt of the planet’s axis of rotation, both occurring over hundreds of thousands of years, have altered the intensity and distribution of sunlight falling on the earth. These phenomena cause a cycle of ice ages and other gradual climate changes. (secondary to HS-ESS2-4) ESS2.A: Earth Materials and Systems The geological record shows that changes to global and regional climate can be caused by interactions among changes in the sun’s energy output or Earth’s orbit, tectonic events, ocean circulation, volcanic activity, glaciers, vegetation, and human activities. These changes can occur on a variety of time scales from sudden (e.g., volcanic ash clouds) to intermediate (Ice ages) to very long-term tectonic cycles. (HSESS2-4) ESS2.D: Weather and Climate The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space. (HS-ESS2-2), (HS-ESS2-4) Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate. (HS-ESS2-6), (HS-ESS2-4) Geoscience Explorations Student Review Semester B 2013-2014 HS-ESS2-5 Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes. Disciplinary Core Idea: ESS2.C: The Roles of Water in Earth's Surface Processes The abundance of liquid water on Earth’s surface and its unique combination of physical and chemical properties are central to the planet’s dynamics. These properties include water’s exceptional capacity to absorb, store, and release large amounts of energy, transmit sunlight, expand upon freezing, dissolve and transport materials, and lower the viscosities and melting points of rocks. (HS-ESS2-5) HS-ESS3-6 Use a computational representation to illustrate the relationships among Earth systems and how those relationships are being modified due to human activity. Disciplinary Core Ideas: ESS2.D: Weather and Climate Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere. (secondary to HS-ESS3-6) ESS3.D: Global Climate Change Through computer simulations and other studies, important discoveries are still being made about how the ocean, the atmosphere, and the biosphere interact and are modified in response to human activities. (HSESS3-6) Unit 4 Earth and Human Activity HS-ESS2-6 Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere. Disciplinary Core Ideas: ESS2.D: Weather and Climate Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen. (HS-ESS2-6), (HS-ESS2-7) Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate. (HS-ESS2-6), (HS-ESS2-4) HS-ESS3-1 Construct an explanation based on evidence for how the availability of natural resources, occurrence of natural hazards, and changes in climate have influenced human activity. Disciplinary Core Ideas: ESS3.A: Natural Resources Resource availability has guided the development of human society. ESS3.B: Natural Hazards Natural hazards and other geologic events have shaped the course of human history; they have significantly altered the sizes of human populations and have driven human migrations. HS-ESS3-2 Evaluate competing design solutions for developing, managing, and utilizing energy and mineral resources based on cost-benefit ratios. Disciplinary Core Ideas: ESS3.A: Natural Resources Geoscience Explorations Student Review Semester B 2013-2014 All forms of energy production and other resource extraction have associated economic, social, environmental, and geopolitical costs and risks as well as benefits. New technologies and social regulations can change the balance of these factors. (HS-ESS3-2) ETS1.B: Developing Possible Solutions When evaluating solutions, it is important to take into account a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts. (secondary to HSESS3-2),(secondary HS-ESS3-4) HS-ESS3-4 Evaluate or refine a technological solution that reduces impacts of human activities on natural systems. Disciplinary Core Ideas: ESS3.C: Human Impacts on Earth Systems Scientists and engineers can make major contributions by developing technologies that produce less pollution and waste and that preclude ecosystem degradation. (HS-ESS3-4) ETS1.B: Developing Possible Solutions When evaluating solutions, it is important to take into account a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts.
