As part of their 'Space' topic in science, Jupiter have looked at 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.  The lit part of the Moon always points the way to the Sun.

Using some polystyrene spheres and a torch, Jupiter tried to recreate how the moon looks at different times of the lunar month.   After some trial and error they managed to show some of the phases....


What is the phase of the moon?

The lunar phase is the amount of the Moon you can see from Earth depending on how much of it is lit up by the sun. This amount changes each day.

What causes part of the Moon to be lit up?

The moon is illuminated because it reflects the light from the sun. The part of the moon facing the sun is lit up. The part facing away from the sun is in darkness.

Did you know?
Countries near the equator see the crescent moon shaped like a smile.
