Demonstrate Earth's Rotation
(Student should spin as if they have an axis)
How long is 1 Earth rotation?
24 hrs (1 day)
How long is 1 Earth revolution?
365 days (1 year)
Demonstrate a Revolution
(Student should walk around an object)
True or False: Earth's Revolution causes day and night
False! Earth's rotation is the cause of day and night.
True or False: The sun and stars move around the Earth.
False! Earth's Rotation makes it look like they are changing positions in the sky.

Earth is rotating
Oh no! The Earth stopped rotating around its own axis! What's going to happen?
One side of the Earth will always face the sun (daytime) and the other side will always face away from the sun (nighttime)
Why is the force of gravity important to Earth's revolution?
It keeps Earth from not moving away from the sun or getting closer to the sun.
Demonstrate the way the Sun and Earth move during a full year.
(A student playing Earth should walk around a student playing the Sun in a full circle.)
True or False: No matter where you are on the planet, Earth's rotation makes it look like every star in the sky is moving.
False! Depending on where the star is located, it might look like it is staying in one spot even though the Earth is rotating.
