This document discusses a grade 3 lesson plan about the Earth's rotation and revolution, phases of the moon, and stars. The lesson plan includes objectives to differentiate rotation from revolution, describe how a star's atmosphere affects its color, identify effects of Earth's movement, and infer that the moon shines through reflected sunlight. Students are asked to relate terms to the solar system, discuss if Earth is moving, and answer questions through discussion, drawings, and demonstrations about the moon's phases and features.
