Group E Day And Night
sourceThis page is all about how days and nights work!

The earth spins on a axis, it takes 24 hours to complete one rotation which is 1 whole day. Different places in the world are at different times such as in New York it is 11 AM whilst in London it is 4 PM this is because the Earth is always spinning on an axis. The axis is an imaginary line that runs from the North Pole to the South Pole. The moon goes round the Earth aproximately every 28 days. The path it takes is called the orbit.

Phases of the Moon
As the moon orbits the Earth, its shape appears to change
everyday. These changes are called the phases of the moon.
