ME.D. The Physical Setting: Students understand the universal nature of matter, energy, force, and motion and identify how these relationships are exhibited in Earth Systems, in the solar system, and throughout the universe.
D.1. Universe and Solar System: Students explain the movements and describe the location, composition, and characteristics of our solar system and universe, including planets, the sun, and galaxies.
D.1.b. Explain the motions that cause days, years, phases of the moon, and eclipses.
D.2. Earth: Students describe the various cycles, physical and biological forces and processes, position in space, energy transformations, and human actions that affect the short- term and long-term changes to the Earth.
D.2.a. Explain how the tilt of Earth's rotational axis relative to the plane of its yearly orbit around the sun affects the day length and sunlight intensity to cause seasons.
