Core Idea - Earth's Place in the Universe

[HS.ESS.1.1] - Use informational text to explain that the life span of the Sun over approximately 10 billion years is a function of nuclear fusion in its core. Communicate that stars, through nuclear fusion over their life cycle, produce elements from helium to iron and release energy that eventually reaches Earth in the form of radiation. State Assessment Boundary: Specific stages of the life of a star, details of the many different nucleosynthesis pathways for stars of differing masses, or calculations of energy released are not expected in state assessment.

Predecessor Standards:

  • 8.PS.1.1
    Develop a model to describe that (a) atoms combine in a multitude of ways to produce pure substances which make up all of the living and nonliving things that we encounter, (b) atoms form molecules and compounds that range in size from two to thousands of atoms, and (c) mixtures are composed of different proportions of pure substances. Clarification Statement: Examples of molecular-level models could include drawings, three-dimensional ball and stick structures, and computer representations showing different molecules with different types of atoms. State Assessment Boundary: Valence electrons and bonding energy, the ionic nature of subunits of complex structures, complete depictions of all individual atoms in a complex molecule or extended structure, or calculations of proportions in mixtures are not expected in state assessment.

Successor Standards:

No Successor Standards found.

Same Level Standards:

  • RCA-ST.9-10.1
    Cite specific textual evidence to support analysis of science and technical texts, attending to the precise details of explanations or descriptions.
  • AI.F-BF.A.1
    Write linear, quadratic, and exponential functions that describe a relationship between two quantities.*
  • HS.ESS.1.2
    Describe the astronomical evidence for the Big Bang theory, including the red shift of light from the motion of distant galaxies as an indication that the universe is currently expanding, the cosmic microwave background as the remnant radiation from the Big Bang, and the observed composition of ordinary matter of the universe, primarily found in stars and interstellar gases, which matches that predicted by the Big Bang theory (3/4 hydrogen and 1/4 helium).
  • HS.PHY.1.8
    Develop a model to illustrate the energy released or absorbed during the processes of fission, fusion, and radioactive decay. Clarification Statements: Examples of models include simple qualitative models, such as pictures or diagrams. Types of radioactive decay include alpha, beta, and gamma. State Assessment Boundary: Quantitative calculations of energy released or absorbed are not expected in state assessment.
