Core Standard
3rd Grade Content
Standard 1
Students will understand that the shape of Earth and the moon are
spherical and that Earth rotates on its axis to produce the appearance of
the sun and moon moving through the sky.
Objective 2
Describe the motions of Earth (i.e., the rotation [spinning] of Earth on its
axis, the revolution [orbit] of Earth around the sun).
Use a model of Earth to demonstrate that Earth rotates on its axis once
every 24 hours to produce the night and day cycle.
