The standards emphasize historical contributions in the development of scientific thought about the Earth and space. The standards stress the interpretation of maps, charts, tables, and profiles; the uses of technology to collect, analyze, and report data; and the utilization of science skills in systematic investigation. Problem solving and decision making are an integral part of the standards, especially as they relate to the costs and benefits of utilizing the Earth’s resources. Major topics of study include earth processes, the rock cycle, Earth history, mapping skills, the oceans, the atmosphere, weather and climate, and the solar system and universe. Philosophy and Goals Educators use the phrase “scientific literacy” to express the major objective of contemporary science education, an aim recognized for all students. In that context, we have assumed the task of developing a curriculum for Earth Science that will contribute to the achievement of one aspect of scientific literacy. The aim of Earth Science literacy must be translated into specific goals for Earth Science education in order for students to learn and understand how to use information in their daily lives. Education in Earth Science should sustain students’ interest in the natural world, help students explore new areas of interest, improve their explanation of earth’s concepts, help them develop understanding and use of inquiry and technology, and contribute to their making informed personal and social decisions. The literate student should develop appropriate personal values regarding scientific investigations, diversity, the impact of science and technology on society, and the importance of Earth Science to the individual. The Earth Science standards continue to focus on student growth in understanding the nature of science. This scientific view defines the idea that explanations of nature are developed and tested using observation, experimentation, models, evidence, and systematic processes. The nature of science includes the concepts that scientific explanations are based on logical thinking; are subject to rules of evidence; are consistent with observational, inferential, and experimental evidence; are open to rational critique; and are subject to refinement and change with the addition of new scientific evidence. The nature of science includes the concept that science can provide explanations about nature, can predict potential consequences of actions, but cannot be used to answer all questions. 2 Grade 9 Earth Science Curriculum Guide 2012 Assessment Students’ prior knowledge will be assessed either formally or informally. Assessment measures include, but are not limited to, tests, quizzes labs, portfolios, presentations, technology-based activities, and projects. One can assess diverse students in a classroom by using diverse methods, including alternative assessment instruments such as portfolios and student production of simulations and models. Assessment instruments are most valuable when they focus on higher-order thinking skills, understanding and use of earth science knowledge, and the demonstration of competence in a setting that is meaningful to students. Assessment should be an ongoing process that begins with a determination of the information and skills students bring to the class and continues with documentation of their progress throughout the course. 3 Grade 9 Earth Science Curriculum Guide 2012 Earth Science STANDARDS OF LEARNING Earth Science Introduction The Science Standards of Learning for Virginia Public Schools identify academic content for essential components of the science curriculum at different grade levels. Standards are identified for kindergarten through grade five, for middle school, and for a core set of high school courses — Earth Science, Biology, Chemistry, and Physics. Throughout a student’s science schooling from kindergarten through grade six, content strands, or topics are included. The Standards of Learning in each strand progress in complexity as they are studied at various grade levels in grades K-6, and are represented indirectly throughout the high school courses. These strands are Scientific Investigation, Reasoning, and Logic; Force, Motion, and Energy; Matter; Life Processes; Living Systems; Interrelationships in Earth/Space Systems; Earth Patterns, Cycles, and Change; and Earth Resources. Five key components of the science standards that are critical to implementation and necessary for student success in achieving science literacy are 1) Goals; 2) K-12 Safety; 3) Instructional Technology; 4) Investigate and Understand; and 5) Application. It is imperative to science instruction that the local curriculum consider and address how these components are incorporated in the design of the kindergarten through high school science program. 4 Grade 9 Earth Science Curriculum Guide 2012 Goals The purposes of scientific investigation and discovery are to satisfy humankind’s quest for knowledge and understanding and to preserve and enhance the quality of the human experience. Therefore, as a result of science instruction, students will be able to achieve the following objectives: 1. Develop and use an experimental design in scientific inquiry. 2. Use the language of science to communicate understanding. 3. Investigate phenomena using technology. 4. Apply scientific concepts, skills, and processes to everyday experiences. 5. Experience the richness and excitement of scientific discovery of the natural world through the collaborative quest for knowledge and understanding. 6. Make informed decisions regarding contemporary issues, taking into account the following: public policy and legislation; economic costs/benefits; validation from scientific data and the use of scientific reasoning and logic; respect for living things; personal responsibility; and history of scientific discovery. 7. Develop scientific dispositions and habits of mind including: curiosity; demand for verification; respect for logic and rational thinking; consideration of premises and consequences; respect for historical contributions; attention to accuracy and precision; and patience and persistence. 8. Develop an understanding of the interrelationship of science with technology, engineering and mathematics. 5 Grade 9 Earth Science Curriculum Guide 2012 9. Explore science-related careers and interests. K-12 Safety In implementing the Science Standards of Learning, teachers must be certain that students know how to follow safety guidelines, demonstrate appropriate laboratory safety techniques, and use equipment safely while working individually and in groups. Safety must be given the highest priority in implementing the K-12 instructional program for science. Correct and safe techniques, as well as wise selection of experiments, resources, materials, and field experiences appropriate to age levels, must be carefully considered with regard to the safety precautions for every instructional activity. Safe science classrooms require thorough planning, careful management, and constant monitoring of student activities. Class enrollment should not exceed the designed capacity of the room. Teachers must be knowledgeable of the properties, use, and proper disposal of all chemicals that may be judged as hazardous prior to their use in an instructional activity. Such information is referenced through Materials Safety Data Sheets (MSDS). The identified precautions involving the use of goggles, gloves, aprons, and fume hoods must be followed as prescribed. While no comprehensive list exists to cover all situations, the following should be reviewed to avoid potential safety problems. Appropriate safety procedures should be used in the following situations: observing wildlife; handling living and preserved organisms; and coming in contact with natural hazards, such as poison ivy, ticks, mushrooms, insects, spiders, and snakes; engaging in field activities in, near, or over bodies of water; handling glass tubing and other glassware, sharp objects, and labware; handling natural gas burners, Bunsen burners, and other sources of flame/heat; working in or with direct sunlight (sunburn and eye damage); using extreme temperatures and cryogenic materials; handling hazardous chemicals including toxins, carcinogens, and flammable and explosive materials; producing acid/base neutralization reactions/dilutions; producing toxic gases; generating/working with high pressures; working with biological cultures including their appropriate disposal and recombinant DNA; 6 Grade 9 Earth Science Curriculum Guide handling power equipment/motors; working with high voltage/exposed wiring; and working with laser beam, UV, and other radiation. 2012 The use of human body fluids or tissues is generally prohibited for classroom lab activities. Further guidance from the following sources may be referenced: OSHA (Occupational Safety and Health Administration); ISEF (International Science and Engineering Fair) rules; and public health departments’ and school divisions’ protocols. Instructional Technology The use of current and emerging technologies is essential to the K-12 science instructional program. Specifically, technology must accomplish the following: Assist in improving every student’s functional literacy. This includes improved communication through reading/information retrieval (the use of telecommunications), writing (word processing), organization and analysis of data (databases, spreadsheets, and graphics programs), presentation of one’s ideas (presentation software), and resource management (project management software). Be readily available and regularly used as an integral and ongoing part of the delivery and assessment of instruction. Include instrumentation oriented toward the instruction and learning of science concepts, skills, and processes. Technology, however, should not be limited to traditional instruments of science, such as microscopes, labware, and data-collecting apparatus, but should also include computers, robotics, video-microscopes, graphing calculators, probeware, geospatial technologies, online communication, software and appropriate hardware, as well as other emerging technologies. Be reflected in the “instructional strategies” generally developed at the school division level. In most cases, the application of technology in science should remain “transparent” unless it is the actual focus of the instruction. One must expect students to “do as a scientist does” and not simply hear about science if they are truly expected to explore, explain, and apply scientific concepts, skills, and processes. As computer/technology skills are essential components of every student’s education, it is important that teaching these skills is a shared responsibility of teachers of all disciplines and grade levels. 7 Grade 9 Earth Science Curriculum Guide 2012 Investigate and Understand Many of the standards in the Science Standards of Learning begin with the phrase “Students will investigate and understand.” This phrase was chosen to communicate the range of rigorous science skills and knowledge levels embedded in each standard. Limiting a standard to one observable behavior, such as “describe” or “explain,” would have narrowed the interpretation of what was intended to be a rich, highly rigorous, and inclusive content standard. “Investigate” refers to scientific methodology and implies systematic use of the following inquiry skills: observing; classifying and sequencing; communicating; measuring; predicting; hypothesizing; inferring; defining, controlling, and manipulating variables in experimentation; designing, constructing, and interpreting models; and interpreting, analyzing, and evaluating data. “Understand” refers to various levels of knowledge application. In the Science Standards of Learning, these knowledge levels include the ability to: recall or recognize important information, key definitions, terminology, and facts; explain the information in one’s own words, comprehend how the information is related to other key facts, and suggest additional interpretations of its meaning or importance; apply the facts and principles to new problems or situations, recognizing what information is required for a particular situation, using the information to explain new phenomena, and determining when there are exceptions; analyze the underlying details of important facts and principles, recognizing the key relations and patterns that are not always readily visible; 8 Grade 9 Earth Science Curriculum Guide 2012 arrange and combine important facts, principles, and other information to produce a new idea, plan, procedure, or product; and make judgments about information in terms of its accuracy, precision, consistency, or effectiveness. Therefore, the use of “investigate and understand” allows each content standard to become the basis for a broad range of teaching objectives, which the school division will develop and refine to meet the intent of the Science Standards of Learning. Application Science provides the key to understanding the natural world. The application of science to relevant topics provides a context for students to build their knowledge and make connections across content and subject areas. This includes applications of science among technology, engineering, and mathematics, as well as within other science disciplines. Various strategies can be used to facilitate these applications and to promote a better understanding of the interrelated nature of these four areas. 9 Grade 9 Earth Science Curriculum Guide 2012 Earth Science The Earth Science standards connect the study of Earth’s composition, structure, processes, and history; its atmosphere, fresh water, and oceans; and its environment in space. The standards emphasize historical contributions in the development of scientific thought about Earth and space. The standards stress the interpretation of maps, charts, tables, and profiles; the use of technology to collect, analyze, and report data; and the utilization of science skills in systematic investigation. Problem solving and decision making are an integral part of the standards, especially as they relate to the costs and benefits of utilizing Earth’s resources. Major topics of study include plate tectonics, the rock cycle, Earth history, the oceans, the atmosphere, weather and climate, and the solar system and universe. The Earth Science standards continue to focus on student growth in understanding the nature of science. This scientific view defines the idea that explanations of nature are developed and tested using observation, experimentation, models, evidence, and systematic processes.

Grade 9 Earth Science Curriculum Guide Understanding Standard ES.2 2012 Essential Understanding, Knowledge, Processes, and Skills Activities and Resources The concepts developed in this standard include the following: In order to meet this standard, it is expected that students will Scientific Method & Safety Rules The nature of science refers to the foundational concepts that govern the way scientists formulate explanations about the natural world. The nature of science includes the concepts a) the natural world is understandable; b) science is based on evidence both observational and experimental; c) science is a blend of logic and innovation; d) scientific ideas are durable yet subject to change as new data are collected; e) science is a complex social endeavor; and f) scientists try to remain objective and engage in peer review to help avoid bias. Observations & Predictions Handout Earth is a dynamic system, and all atmospheric, lithospheric, and hydrospheric processes interrelate and influence one another. ix A hypothesis is a tentative explanation that accounts for a set of facts and can be tested by further investigation. Only hypotheses that are testable are valid. A analyze how natural processes explain multiple aspects of Earth systems and their interactions (e.g., storms, earthquakes, volcanic eruptions, floods, climate, mountain chains and landforms, geological formations and stratigraphy, fossils) can be used to make predictions of future interactions and allow scientific explanations for what has happened in the past. make predictions, using scientific data and data analysis. use data to support or reject a hypothesis. differentiate between systematicallyobtained, verifiable data and unfounded claims. evaluate statements to determine if systematic science is used correctly, consistently, thoroughly, and in the proper context. distinguish between examples of observations and inferences. explain how scientific methodology is used to support, refute, or improve scientific theories. contrast the formal, scientific use of the term “theory” with the everyday Scientific Methods in Earth Science Scientific Method Bikini Bottom Experiments Observation & Inference statements Air Plane Lab Gummy Bear Lab Origami Jumping Frog Lab Grade 9 Earth Science Curriculum Guide hypothesis can be supported, modified, or rejected based on collected data. Experiments are designed to test hypotheses. Scientific theories are systematic sets of concepts that offer explanations for observed patterns in nature. Theories provide frameworks for relating data and guiding future research. Theories may change as new data become available. Any valid scientific theory has passed tests designed to invalidate it. There can be more than one scientific explanation for phenomena. However, with competing explanations, generally one idea will eventually supersede the other as new tools, new observations, and verified data become available. Changing relevant variables will generally change the outcome. Scientific laws are generalizations of observational data that describe patterns and relationships. Laws may change as new data become available. 2012 nontechnical usage of “theory.” 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 is the third planet from the sun and is located between the sun and the asteroid belt. It has one natural satellite, the moon. Water occurs on Earth as a solid (ice), a liquid, or a gas (water vapor) due to Earth’s position in the solar system. Earth revolves around the sun tilted on its axis. The axial tilt is responsible for the incidence and duration of sunlight striking a given hemisphere that varies during the Earth’s revolution around the Sun, thus causing seasons. Equinoxes and solstices represent four distinct quarterly points signaling the cyclic change of seasons. The moon revolves around Earth creating the moon phases and eclipses.

The rock cycle is the process by which all rocks are formed and how basic Earth materials are recycled through time. xvii Rocks can be identified on the basis of mineral content and texture. Igneous rock forms from molten rock that cools and hardens either below or on Earth’s surface. Extrusive igneous rocks have small or no crystals, resulting in fine-grained or glassy textures and include pumice, obsidian, and basalt. Intrusive igneous rocks have larger crystals and a coarser texture and comprehend and identify various igneous rock textural features and mineral components with a hand sample or by description, and analyze the significance of these features in terms of mode of origin and history. analyze and identify various sedimentary rocks in terms of mode of origin and history, using sedimentary features (grain size, texture, and composition). analyze the major groups of metamorphic rocks for mineral composition and textural features and determine the potential parent rock and in terms of the rock cycle.

Virginia has five physiographic provinces produced by past episodes of tectonic activity and continuous geologic activity. Each province has unique physical characteristics resulting from its geologic past. iii 2012 Geologic processes produce characteristic structures and features. The five physiographic provinces of Virginia are Coastal Plain, Piedmont, Blue Ridge, Valley and Ridge, and Appalachian Plateau. The Coastal Plain is a flat area composed of young, unconsolidated sediments underlain by older crystalline basement rocks. These layers of sediment were produced by erosion of the Appalachian Mountains and Piedmont and then deposited on the Coastal Plain when sea levels were higher in the past. The Piedmont is an area of rolling hills underlain by mostly ancient igneous and metamorphic rocks.

Key concepts include a) processes of soil development; b) development of karst topography; c) relationships between groundwater zones, including saturated and unsaturated zones, and the water table; d) identification of sources of fresh water including rivers, springs, and aquifers, with reference to the hydrologic cycle; e) dependence on freshwater resources and the effects of human usage on water quality; and f) identification of the major watershed systems in Virginia, including the Chesapeake Bay and its tributaries. Soil is formed from the weathering of rocks and organic activity and is composed of loose rock fragments and clay derived from weathered rock mixed with organic material. Karst topography is developed in areas underlain by carbonate rocks, including limestone and dolomite. Karst topography includes features like caves and sinkholes and forms when limestone is slowly dissolved away by slightly acidic groundwater. Where limestone is abundant in the Valley and Ridge province of Virginia, karst topography is common. Permeability is a measure of the ability of a rock or sediment to transmit water or other liquids. Water does not pass through impermeable materials. A substantial amount of water is stored in permeable soil and rock underground. Earth’s fresh water supply is finite. Geological processes, such as erosion, and human activities, such as waste disposal, can pollute water supplies. Water is continuously being passed through the hydrologic cycle. Fresh water is necessary for survival and most human activities. interpret a simple groundwater diagram showing the zone of aeration, the zone of saturation, the water table, and an aquifer. interpret a simple hydrologic cycle diagram, including evaporation, condensation, precipitation, and runoff. locate the major Virginia watershed systems on a map (Chesapeake Bay, Gulf of Mexico, and North Carolina sounds). analyze the formation of karst in terms of rock type, solubility and permeability, uplift, the water table, and chemical and physical weathering. analyze the presence of groundwater in various types of rock terrains, including areas found in each of the physiographic provinces of Virginia. analyze the relationship between saltwater intrusion in the ground water in certain areas of eastern Virginia and buried crater structures.

Evidence of ancient, often extinct life is preserved in many sedimentary rocks. A fossil is the remains, impression, or other evidence preserved in rock of the former existence of life. Fossil evidence indicates that life forms have changed and become more complex over geologic time. Some ways in which fossils can be preserved are molds, casts, and original bone or shell. Relative time places events in a sequence without assigning any numerical ages. Fossils, superposition, and cross-cutting relations are used to determine the relative ages of rocks. Absolute time places a numerical age on an event. Radioactive decay is used to determine the absolute age of rocks. The age of Earth is about 4.6 billion years.

The ocean is a dynamic system in which many chemical, biological, and physical changes are taking place. The oceans are an important source of food and mineral resources as well as a venue for recreation and transportation. Sea level falls when glacial ice caps grow and rises when the ice caps melt. Most waves on the ocean surface are generated by wind. There are large current systems in the oceans that carry warm water towards the poles and cold water towards the equator. Upwellings bring cold, nutrient-rich water from the deep ocean to the surface and are areas of rich biological activity. relate important ocean conditions, including El Niño, to weather on the continents. evaluate the role of the marine environment in the extraction of carbon dioxide in carbonates and the production of oxygen. xi 2012 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.

After the moon was formed, the early atmosphere contained mostly CO2, CO, and water vapor. This atmosphere was then modified by early photosynthetic life. Early photosynthetic life such as cyanobacteria (blue-green algae) consumed carbon dioxide and generated oxygen. It was only after early photosynthetic life generated oxygen that animal life became possible. Earth’s atmosphere is 21 percent oxygen, 78 percent nitrogen, and 1 percent trace gases. The composition of the atmosphere can change due to human, biologic, and geologic activity. Human activities have increased the carbon dioxide content of the atmosphere. Manmade chemicals have decreased the ozone concentration in the upper atmosphere. Volcanic activity and meteorite impacts can inject large quantities of dust and gases into the atmosphere. The ability of Earth’s atmosphere to absorb and retain heat is affected by the presence of gases like water vapor and carbon dioxide. and contrast these feedback mechanisms to those operating on inner planets and the gas giants. analyze the evidence for atmospheric compositional change over geologic time including oxygen and carbon sinks and the role of photosynthetic organisms. explain how volcanic activity or meteor impacts could affect the atmosphere and life on Earth. explain how biologic activity, including human activities, may influence global temperature and climate.

Winds are created by uneven heat distribution at Earth’s surface and modified by the rotation of Earth. The Coriolis effect causes deflections of the atmosphere due to the rotation of Earth. Global wind patterns result from the uneven heating of Earth by the sun and are influenced by the Coriolis effect. Convection in the atmosphere is a major cause of weather. Convection is the major mechanism of energy transfer in the oceans, atmosphere, and Earth’s interior. The conditions necessary for cloud formation are air at or below dew point and presence of condensation nuclei. Cloud droplets can join together to form precipitation. A tornado is a narrow, violent funnelshaped column of spiral winds that extends downward from the cloud base toward Earth. A hurricane is a tropical cyclone (counterclockwise movement of air) characterized by sustained winds of 120 kilometers per hour (75 miles per 2012 masses, fronts and the accompanying weather conditions. Energy Pathways in Earth’s Atmosphere read and interpret climate graphs. Heat Transfer Lab label a diagram of global climate zones and the surface movement of ocean currents. Heat absorption Lab label a diagram that demonstrates the interaction of Earth’s atmosphere and energy transfer (conduction, convection, and radiation). Hurricanes analyze the impact of satellite technology on weather prediction and the tracking of severe storms, including hurricanes, and evaluate the cost and benefits of this technology in terms of lives and property saved.

The Big Bang theory is our best current model for the origin of the universe. The Big Bang theory states that the universe began in a very hot, dense state that expanded and eventually condensed into galaxies. ii The student will investigate and understand scientific concepts related to the origin and evolution of 2012 the universe. Key concepts include a) cosmology including the Big Bang theory; and b) the origin and evolution of stars, star systems, and galaxies. contrast the life span and energy output of a blue giant star to that of the sun and relate this to the potential existence of life on planets in its orbit. explain the potential origin and role of ultra massive black holes in the center of galaxies. The solar nebular theory is our best current idea for the origin of the solar system. The solar nebular theory explains that the planets formed through the condensing of the solar nebula. using the Hertzsprung-Russell diagram, classify stars as to their place on the main sequence or in beginning or end points in their life cycles. Stars have a finite lifetime and evolve over time. The mass of a star controls its evolution, lifespan, and ultimate fate. Stars form by condensation and gravitational compression of interstellar gas and dust. evaluate the probability of travel to nearby solar systems using current spacecraft speeds. analyze the various fusion products of a blue giant star over its lifetime, and relate this to the presence and abundance of elements that make up our solar system and its contents, including living organisms. The Hertzsprung-Russell diagram illustrates the relationship between the absolute magnitude and the surface temperature of stars. As stars evolve, their position on the Hertzsprung-Russell diagram moves. Galaxies are collections of billions of stars. The basic types of galaxies are spiral, elliptical, and irregular. The solar system is located in the Milky Way galaxy. A light-year is the distance light travels in one year and is the most commonly used measurement for distance in Activities and Resources The Expanding Universe How Far and How Fast?

The blueprint indicates the content areas that will be addressed by the test and the number of items that will be included by content area and for the test as a whole. There is a blueprint for each test (e.g., grade 3 reading, grade 5 mathematics, grade 8 science, Virginia and United States History). Reporting Categories Each test covers a number of Standards of Learning (SOL). In the test blueprint, the SOL are grouped into categories that address related content and skills. These categories are labeled as reporting categories. For example, a reporting category for the Earth Science Standards of Learning test is Earth and Space Systems. Each of the SOL in this reporting category addresses a skill involved in investigating or understanding the concepts of force, motion, energy, or matter. When the results of the SOL tests are reported, the scores will be presented for each reporting category and as a total test score. Assignment of Standards of Learning to Reporting Category Different parts of a Standard of Learning may be assigned to different reporting categories. For example, Earth Science SOL ES.8a, which covers processes of soil development, is assigned to the reporting category Earth and Materials and Processes in the Earth Science SOL test. However, ES.8c, which involves relationships between groundwater zones, is assigned to the reporting category Earth and Space Systems. Standards of Learning Excluded from Testing In some content areas, there are SOL that do not lend themselves to assessment within the current format of the SOL tests. The SOL not tested are listed as “Excluded from Testing” at the end of the blueprint for each test. In Earth Science there are no SOL that are excluded within the current format of the SOL tests. 9 Grade 9 Earth Science Curriculum Guide Coverage of Standards of Learning Due to the large number of SOL in each grade level content area, every Standard of Learning will not be assessed on every version (form) of an SOL test. By necessity, to keep the length of a test reasonable, each version will sample from the SOL within a reporting category. All SOL in the blueprint will be tested within a three year period, and all of these SOL are eligible for inclusion on each version of an SOL test. Use of the Curriculum Framework The Earth Science Standards of Learning, amplified by the Curriculum Framework, define the essential understandings, knowledge, and skills that are measured by the Standards of Learning tests. The Curriculum Framework identifies essential understandings, defines essential content knowledge, and describes essential skills students need to master. 10 2012 Grade 9 Earth Science Curriculum Guide 2012 Earth Science Test Blueprint Summary Table Reporting Category Assessed with Other SOL Scientific Investigation and the Nature of Science Earth and Space Systems Earth Materials and Processes Cosmology, Origins, and Time Earth Resources and Human Interactions Excluded from Testing Number of Operational Items Number of Field Test Items* Total Number of Items on Test Earth Science Standards of Learning Number of Items ES.1f ES.1a-e ES.2a-d ES.3a-c ES.8c-d ES.10a, c-d ES.12a-d ES.4a ES.5a-c ES.7a-b ES.8a-b ES.9a-d ES.11a-c ES.13a-b ES. 3d ES.4b ES.6a-d ES.8e-f ES.10b, e ES.11d None *Field test items are being tried out with students for potential use on subsequent tests and will not be used to compute students’ scores on the test. 11 10 10 10 10 10 50 10 60 Grade 9 Earth Science Curriculum Guide 2012 Earth Science Expanded Test Blueprint Assessed with Other Science Standards of Learning The following skill-based standards will be assessed through the reporting categories by applying them to other Standards of Learning content: ES.1 The student will plan and conduct investigations in which f) current applications are used to reinforce Earth science concepts.
