Standard I - Earth and Moon
Standard: 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 1: Describe the appearance of Earth and the moon.
Objective 2: Describe the movement of Earth and the moon and the apparent movement of other bodies through the sky.
Earth orbits around the sun, and the moon orbits around Earth. Earth is spherical in shape and rotates on its axis to produce the night and day cycle. To people on Earth, this turning of the planet makes it appear as though the sun, moon, planets, and stars are moving across the sky once a day. However, this is only a perception as viewed from Earth.
