Showing 1 - 2 of 2 Standards

Standard Identifier: K-ESS3-2

Grade: K
Disciplinary Core Idea: ESS3.B: Natural Hazards, ETS1.A: Defining and Delimiting Engineering Problems
Cross Cutting Concept: CCC-2: Cause and Effect: Mechanism and Explanation
Science & Engineering Practice: SEP-1: Asking Questions and Defining Problems
Content Area: Earth and Space Science

Title: K-ESS3 Earth and Human Activity

Performance Expectation: Ask questions to obtain information about the purpose of weather forecasting to prepare for, and respond to, severe weather.* [Clarification Statement: Emphasis is on local forms of severe weather.]

Disciplinary Core Idea(s):
ESS3.B: Natural Hazards Some kinds of severe weather are more likely than others in a given region. Weather scientists forecast severe weather so that the communities can prepare for and respond to these events. ETS1.A: Defining and Delimiting Engineering Problems Asking questions, making observations, and gathering information are helpful in thinking about problems. (secondary to K-ESS3-2)

Science & Engineering Practices: Asking Questions and Defining Problems Ask questions based on observations to find more information about the designed world.

Crosscutting Concepts: Cause and Effect Events have causes that generate observable patterns. Connections to Engineering, Technology, and Applications of Science: Interdependence of Science, Engineering, and Technology People encounter questions about the natural world every day. Influence of Engineering, Technology, and Science on Society and the Natural World People depend on various technologies in their lives; human life would be very different without technology.

California Environmental Principles and Concepts:
Principle I The continuation and health of individual human lives and of human communities and societies depend on the health of the natural systems that provide essential goods and ecosystem services. Principle II The long-term functioning and health of terrestrial, freshwater, coastal and marine ecosystems are influenced by their relationships with human societies.

California Common Core State Standards Connections:
ELA/Literacy RI.K.1: With prompting and support, ask and answer questions about key details in a text. SL.K.3: Ask and answer questions in order to seek help, get information, or clarify something that is not understood. Mathematics MP.4: Model with mathematics. K.CC.1-3: Know number names and the count sequence. K.CC.4-5: Count to tell the number of objects. K.CC.6-7: Compare numbers.

Standard Identifier: HS-ESS1-1

Grade Range: 9–12
Disciplinary Core Idea: ESS1.A: The Universe and its Stars, PS3.D: Energy in Chemical Processes
Cross Cutting Concept: CCC-3: Scale, Proportion, and Quantity
Science & Engineering Practice: SEP-2: Developing and Using Models
Content Area: Earth and Space Science

Title: HS-ESS1 Earth’s Place in the Universe

Performance Expectation: Develop a model based on evidence to illustrate the life span of the sun and the role of nuclear fusion in the sun’s core to release energy that eventually reaches Earth in the form of radiation. [Clarification Statement: Emphasis is on the energy transfer mechanisms that allow energy from nuclear fusion in the sun’s core to reach Earth. Examples of evidence for the model include observations of the masses and lifetimes of other stars, as well as the ways that the sun’s radiation varies due to sudden solar flares (“space weather”), the 11-year sunspot cycle, and non-cyclic variations over centuries.] [Assessment Boundary: Assessment does not include details of the atomic and sub-atomic processes involved with the sun’s nuclear fusion.]

Disciplinary Core Idea(s):
ESS1.A: The Universe and its Stars The star called the sun is changing and will burn out over a lifespan of approximately 10 billion years. PS3.D: Energy in Chemical Processes Nuclear Fusion processes in the center of the sun release the energy that ultimately reaches Earth as radiation. (secondary to HS-ESS1-1)

Science & Engineering Practices: Developing and Using Models Develop a model based on evidence to illustrate the relationships between systems or between components of a system.

Crosscutting Concepts: Scale, Proportion, and Quantity The significance of a phenomenon is dependent on the scale, proportion, and quantity at which it occurs.

California Common Core State Standards Connections:
ELA/Literacy RST.11-12.1: Cite specific textual evidence to support analysis of science and technical texts, attending to important distinctions the author makes and to any gaps or inconsistencies in the account. Mathematics MP.2: Reason abstractly and quantitatively. MP.4: Model with mathematics. N-Q.1-3: Reason quantitatively and use units to solve problems. A-SSE.1.a-b: Interpret expressions that represent a quantity in terms of its context. A-CED.2: Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales. A-CED.4: Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations. HSN-Q.A.2: Define appropriate quantities for the purpose of descriptive modeling. HSN-Q.A.3: Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.
