Unit 8 Astronomy

NYSSLS Performance Expectations (Objectives)

  • HS-ESS1-1: 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.
  • HS-ESS1-2: Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe.
  • HS-ESS1-3: Communicate scientific ideas about the way stars, over their life cycle, produce elements.
  • HS-ESS1-4: Use mathematical or computational representations to predict the motion of orbiting objects in the solar system.
  • HS-ESS1-7 (NY-specific): Construct an explanation using evidence to support the claim that the phases of the Moon, eclipses, tides, and seasons change cyclically.

Extraneous Content (No Longer Required)

  • Detailed planet characteristics memorization (diameter, distance, composition for all planets)
  • Foucault pendulum demonstrations (concept retained, calculations reduced)
  • Coriolis effect detailed calculations
