Science Understanding / Earth and space sciences. Predictable phenomena on Earth, including seasons and eclipses, are caused by the relative positions of the sun, Earth and the moon (ACSSU115). - investigating natural phenomena such as lunar and solar eclipses, seasons and phases of the moon.
When the Moon moves between Earth and the Sun, it casts a small shadow on Earth, and people inside that shadow see a solar eclipse. Both these events are rare, happening only about every 6 months. Moon phases are the result of the Moon's own shadow -- like Earth, only one half of the body is lit at a time. Sometimes the lit side is pointed toward Earth, and we see the reflected light. Sometimes the shadow or night side is pointed toward Earth, and we only see a crescent Moon.
