Expectations

SAST2.a
Develop and use models to evaluate the relationship between the relative positions of the Earth, Moon and Sun and observable phenomena. (Clarification statement: This includes moon phases, eclipses, tides, and seasons.)
SAST2.b
Plan and carry out an investigation using the celestial sphere to explain how latitude and time of year affect visibility of constellations and other celestial objects.
SAST2.c
Develop and use models of relative orbital motion of planets within our solar system to explain retrograde motion.
SAST2.d
Use mathematics and computational thinking to explain the relationship between the properties of light and the vast distances in the cosmos. (Clarification statement: This includes but is not limited to the Doppler Effect, cosmological red shifts, parsecs, light years, and astronomical units.)
SAST2.e
Plan and carry out an investigation to analyze the electromagnetic spectrum and spectroscopic data to obtain information about the inherent properties and motions of objects. (Clarification statement: Consider the use of diffraction gratings to analyze spectroscopic wavelength data along with other quantitative telescopic data.)
