Graduates will: • Understand and apply principles of scientific investigation. • Utilize the key concepts and principles of life, earth, and physical science to solve problems. • Recognize that science is an ongoing human endeavor that helps us understand our world. • Realize that science, mathematics, and technology are interdependent, each with strengths and limitations that impact the environment and society. • Use scientific knowledge and scientific ways of thinking for individual and social purposes. Course Rationale Science education develops science literacy. Scientific literacy is the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity. A sound grounding in science strengthens many of the skills that people use every day, like solving problems creatively, thinking critically, working cooperatively in teams, using technology effectively, and valuing life-long learning. Scientific literacy has become a necessity for everyone. To accomplish this literacy, science courses will reflect the following: • Develop scientific reasoning and critical thinking skills. • Extend problem-solving skills using scientific methods. • Include lab-based experiences. • Strengthen positive attitudes about science. • Incorporate the use of new technologies. • Provide relevant connections to personal and societal issues and events. Course Description for Science 6 - Earth Science This course is designed to have students explore the many facets of Earth science through the use of scientific inquiry, technology and hands-on activities. The course focuses on three main topics: study of Earth’s surface and forces that change it, study of weather, climate and factors that affect them, and study of our solar system and interactions of objects in it. Scientific inquiry and the environment are embedded into each unit. Students are encouraged to ask questions, explore questions, and assess human activity on Earth’s resources and systems.

Standard Students Will Be Able to … Plate Tectonics • Describe the interior structure of the Earth (crust, mantle, and core) • Explain convection currents are the result of uneven heating inside the mantle resulting in the melting of rock materials, convection of magma, eruption/flow of magma, and movement of crustal plates (DOK 2) ES2B8a • Describe how the movement of crustal plates can cause earthquakes and volcanic eruptions that can result in mountain building and trench formation (DOK 1) ES2B8c • Explain how rock layers are affected by the folding, breaking, and uplifting of rock layers due to plate motion ( DOK 2) ES2B8b • Identify events (earthquakes, volcanic eruptions) and the landforms created by them on the Earth’s surface that occur at different plate boundaries ( DOK 2) • Describe ways in which science and society influence one another (e.g., scientific knowledge and the procedures used by scientists influence the way many individuals in society think about themselves, others, and the environment; societal challenges often inspire questions for scientific research; social priorities often influence research priorities through the availability of funding for research) (Wegner & Hess) Rocks and Minerals • Describe the distinguishing properties that can be used to classify minerals (i.e., texture, smell, luster, hardness, crystal shape, streak, reaction to magnets and acids) (DOK 1) FHSD Academics ___ Standard Curriculum 2.0 Page 6 ES2B6a ST3Ba ES1A8b Revised 20__ • • • • • • • • • • • Rocks and Minerals Mineral are identified by testing their physical properties. Physical properties used to identify minerals include: hardness, luster, cleavage/fracture, streak, etc. Rocks are identified based on how they are formed. The three main types of rocks are: igneous, sedimentary, and metamorphic. The continuous changing of rocks from one type to another is called the rock cycle. Matter cannot be created or destroyed; it can only be transformed from one form to another. (Law of Conservation of Matter) Humans impact the environment both positively and negatively. Renewable resources can be replenished with the passage of time either through biological reproduction or other naturally recurring processes. Nonrenewable resources are ones that form at a rate that is much slower than the rate at which they are consumed. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources. Non-renewable resources are limited.
