Learning Objective
Analyze and interpret data of observable patterns to show that Earth rotates on its axis and revolves around the Sun. Emphasize patterns that provide evidence of Earth's rotation and orbits around the Sun. Examples of patterns could include day and night, daily changes in length and direction of shadows, and seasonal appearance of some stars in the night sky. Earth's seasons and its connection to the tilt of Earth's axis will be taught in Grades 6 through 8
- 1
A year is the unit of time that measures how long it takes the Earth to complete one revolution around the Sun.
- 2
The Earth's tilt on its axis is responsible for the Earth's seasons, as the amount of direct sunlight varies throughout the year.
- 3
The Earth's rotation causes streams of moving particles in the outer core to create an invisible magnetic field that protects the planet from harsh radiation.
