Audio Guide:
As the moon orbits around Earth, it also revolves on its axis; and the two cycles are identical. Therefore, when the moon orbits around Earth in a full circle, it also completes one revolution. As a result, the moon always faces Earth with the same side.
Visitors can control the revolution speed and find out when the other side of the moon will turn to Earth.

Exhibit Introduction:
The visitors can select different speeds of rotation by pressing different buttons to control the move of the moon, witnessing the reason why the moon always face the earth with the same side and how the moon changes with different speeds of rotation through experiments.
