ESS.4.1 Understand the causes of day and night and phases of the moon.
ESS.4.1.1 Use models to explain the cause of day and night based on the rotation of the Earth on its axis.
ESS.4.1.2 Use models to explain the repeating pattern of the phases of the moon (new, crescent, quarter, gibbous, and full).

Students will understand that...
ESS.4.1.1
Students know the Earth is spherical in shape and that it rotates on an axis.
Students know each complete rotation takes about 24-hours (a day).
Students use models to show how Earth’s rotation causes one side of the planet to receive light rays from the sun (day) while the other side remains dark (night).
ESS.4.1.2
Students recognize the Earth has one moon that revolves around it.
Students know the appearance of the moon changes in a specific pattern (waxes- more illuminated area; and wanes- less illuminated area) and repeats this sequence over the course of approximately 28 days.
Students know the moon’s appearance (phase) is determined by its position relative to the Earth and the sun.
Students recognize the following phases of the moon: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.
