Unit 3 - Sun, Moon, and Earth

S4E2. Obtain, evaluate, and communicate information to model the effects of the position and motion of the Earth and the moon in relation to the sun as observed from the Earth.

S4E2a. Develop a model to support an explanation of why the length of day and night change throughout the year.

S4E2b. Develop a model based on observations to describe the repeating pattern of the phases of the moon (new, crescent, quarter, gibbous, and full).

S4E2c. Construct an explanation of how the Earth’s orbit, with its consistent tilt, affects seasonal changes.
