Many students think that the phases of the Moon are caused by the Earth casting a shadow on the Moon

  • Phases of the Moon (11-14)

    The moon's appearance changes in a regular way, moving through a sequence of phases in one lunar month.

    The Moon orbits the Earth once every 27.3 days. This means that its position relative to someone standing on the Earth at midnight will change over the course of a month. The phases of the Moon are caused by the changing position of the Moon relative to the Sun and to an observer on the Earth.

  • The moon - our nearest neighbour (5-11)

    The reason for the shape of the Moon changing periodically, going through its different phases is tricky and widely misunderstood. This is not caused by the Moon being in the shadow of the Earth. It is caused by where the Moon is in relation to the Sun and the Earth and so how you see the Sunlight reflecting off the Moon. It really is best not to try to explain this to primary children.
