When the side of Earth where you live faces the sun, you have daylight, and the other side of the world is in darkness, or night.
As Earth spins, your part of the world turns away from the sun, into night, and the other half of the world turns to face the sun.
When it’s dark outside, you know that it’s nighttime. But why does it get dark?
Because Earth spins!
Earth gets daylight from the sun, but only one side of Earth faces the sun at a time. It takes 24 hours—one whole day— for Earth to make one complete spin.
See for yourself. You be Earth, and let a friend be the sun. Ask your friend to shine a flashlight at you from across a dark room while you slowly spin around in place.

Reaching For The Moon
