Day and Night

Yesterday we used spheres to model the Sun, Earth and Moon.

The Sun is the largest object in the solar system. It is gigantic compared with the Earth, which is larger than the moon.

We used our spheres to show how the Earth spins on its axis (once every 24 hours causing day and night) and orbits around the sun (taking a year to do so). When the Earth is not facing the sun it is night.

There are some great websites such as ABC splash and NASA which show the process clearly too.
