Grade 4: Phases of the moon

The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. From Earth we see the Moon grow from a thin crescent to a full disk (or full moon) and then shrink back to a thin crescent again before vanishing for a few days.
The Moon phases are produced by the alignment of the Moon and the Sun in the sky.

What is the phase of the moon?
The changing shape of the bright part of the Moon that we see is called its phase.

What causes the different phases of the Moon?
The phases of the Moon depend on its position in relation to the Sun and Earth. As the Moon makes its way around the Earth, we see the bright parts of the Moon's surface at different angles. These are called "phases" of the Moon.

Our children sang this song to remember the 8 phases of the moon.They liked it a lot:
