Science Curriculum Matrix Earth Sci ence Version 1.0 beta June 2, 2008 This curriculum (core matrix) document will eventually become part of the Science Curriculum Matrix. We envision the Science Curriculum Matrix as on online resource that is organized by both concepts and topics and linked to exemplar instructional resources. This version is currently organized by the Science Standards of Learning for convenience only. In addition to this document, we recommend that you review the Earth Science Curriculum Framework for additional clarification regarding the Earth Science SOL. The other important document for review is the Earth Science Enhanced Scope and Sequence for unit and lesson planning resources. Unfortunately, the Virginia Department of Education has not yet released this document. We will let you know as soon as it is available. Please use these documents in your instructional planning and let us know how we can make improvements. Please contact Chuck Pace with your comments and suggestions at cpace@k12albemarle.org. Thanks, The Science Vertical Team
Scientific Investigation, Reasoning, and Logic The Science Vertical Team will work to develop a recommended integration for the science processes and skills generally found in standard ES.1 into the more content specific standards ES.2 through ES.14. In the meantime, Virginia Science SOL ES.1 and the associated essential skills and processes are presented below. Please incorporate these specific science processes and skills into your daily science instruction as much as possible and practical. ES.1 The student will plan and conduct investigations in which: a. volume, area, mass, elapsed time, direction, temperature, pressure, distance, density, and changes in elevation/depth are calculated utilizing the most appropriate tools; b. technologies, including computers, probeware, and global positioning systems (GPS) are used to collect, analyze, and report data and to demonstrate concepts and simulate experimental conditions; c. scales, diagrams, maps, charts, graphs, tables, and profiles are constructed and interpreted; d. variables are manipulated with repeated trials; and e. a scientific viewpoint is constructed and defended (the nature of science). Essential Skills and Processes In order to meet this standard, it is expected that students should be able to: Measure mass and volume of materials in the lab. Calculate density. Interpret data from a graph or table that shows change in mass, density, or temperature over time. Interpret data from a graph or table that shows changes in temperature or pressure with depth. Compare topographic maps of different scales. Construct a graph, table, chart, and/or diagram from data. Interpret graphs and diagrams. Use scientific methodology to design and test a hypothesis. Compare and contrast hypotheses, theories, and scientific laws. For example, students should be able to compare/contrast the Law of Superposition and the Theory of Plate Tectonics.
Earth Science: Scientific Investigation, Seasoning, and Logic CONCEPT: COMMUNICATION: Models, Theory Earth is a dynamic system, and all atmospheric, geological, and oceanographic processes interrelate and influence one another. Conclusions are only as good as the quality of the collected data. Any valid hypothesis can be tested. Any valid scientific theory has passed tests designed to invalidate it. A hypothesis can be supported, modified, or rejected based on collected data. Experiments are designed to test hypotheses. There can be more than one explanation for any phenomena. How would you define a hypothesis?

The processes by which rocks are formed define the three major groups of rocks. The rock cycle is the process by which all rocks are formed and how basic Earth materials are recycled through time. Classify the following rock types and textures: pumice, obsidian, basalt, granite, sandstone, conglomerate, shale, limestone, slate, schist, gneiss, marble, and quartzite.

Modern living standards are supported by extensive use of both renewable and nonrenewable resources. Extraction and use of any resource carries an environmental cost that must be weighed against economic benefit.

(a) how geologic processes are evidenced in the physiographic provinces of Virginia including the Coastal Plain, Piedmont, Blue Ridge, Valley and Ridge, and Appalachian Plateau.
Earth Science: Earth Patterns, Cycles, and Change: Geology CONCEPT: SYSTEMS: Processes Weathering, erosion, and deposition are interrelated processes. The core, mantle, and crust of Earth are dynamic systems, constantly in motion. Earth s lithosphere is divided into plates that are in motion with respect to one another. Most geologic activity occurs as a result of relative motion along plate boundaries. Plate motion occurs as a consequence of convection in Earth s mantle. Plate tectonics is driven by convection in the mantle. There are two different types of crust oceanic and continental that have very different characteristics. Define chemical and mechanical (physical) weathering, and provide an example of each. Illustrate, using an exposed granite rock, the processes that could weather the rock, erode the weathered material, and possible depositional environments for the eroded material. Be sure to indicate the type of weathering occurring and the agent(s) of erosion involved. Given current rates and directions of movement, predict the future topography of the western North American Plate and the eastern half of the Pacific Plate in 10 million, 100 million, and 500 million years. Identify relative plate motions and geologic features such as types of volcanoes, types of faults, and mountains, ridges, or rifts that may form. weathering erosion deposition lithosphere convection plate tectonics core mantle continental crust oceanic crust subduction sea floor spreading SOL: ES.8 The student will investigate and understand geologic processes including plate tectonics.

On map of Virginia, identify the rivers that are part of the Chesapeake Bay watershed. Label a simple hydrologic cycle diagram, including evaporation, condensation, precipitation, and runoff. Interpret a simple groundwater diagram showing the zone of aeration, the zone of saturation, the water table, and an aquifer.

The oceans are environmentally and economically important. Human activities and public policy have important consequences for the oceans. The oceans resources are finite and should be utilized with care. The impact of human activities, such as waste disposal, construction, and agriculture, affect the water quality within watershed systems and ultimately the ocean. Identify on a world map the warm and cold-water surface currents and the direction in which they flow. Identify the effects of human activities on the oceans. Illustrate the earth s waters, showing high and low tide areas and why there are generally two high and low tide periods daily. Write a letter to a state official outlining how chemical pollution and overfishing can harm or deplete valuable resources. Compare the relationship between density currents and surface currents as they circulate the world s ocean water.

Earth Science: Earth Patterns, Cycles, and Change: Oceanography CONCEPT: CHANGE & CONSTANCY: Equilibrium and SYSTEMS: Relationships Convection is the major mechanism of energy transfer in the oceans, atmosphere, and Earth s interior. The ocean is the single largest reservoir of heat at Earth s surface. The topography of the seafloor is at least as variable as that on the continents. Explain why coastal areas are generally cooler in the summer and warmer in the winter than inland areas at the same latitude. Using a physical map of the world as a guide, sketch a cross-section of the ocean floor and compare it to a cross-section of the North American continent. Predict what would happen to Earth s oceans and atmosphere if water absorbed and radiated heat as quickly as land masses. mid-ocean ridges trenches continental shelf continental slope abyssal plain seamount SOL: ES.11 The student will investigate and understand that oceans are complex, interactive physical, chemical, and biological systems and are subject to long- and short-term variations.
