Day and Night

Open to everyone until Saturday, October 24

To keep it, print it while it is open.

The Earth is a ball that spins around like a top. The side facing the Sun is bright and has day, and the other side is dark and has night.

In the picture

  1. The sunlit half of the globe: the side turned toward the Sun, where it is day.
  2. The dark half of the globe: the side turned away from the Sun, where it is night.
  3. The curved arrow around the globe: one full spin takes about 24 hours.

Examples

  • You wake up in the morning when your side of the Earth turns into the sunlight.
  • While you eat lunch, children on the other side of the world are sleeping in the dark.
