The Moon Phases

THE PHASES OF THE MOON, is a playable postcard that lets us discover the lunar calendar by rotating two superimposed surfaces inside the frame and on the same axis. The background is a white surface with a black circle, the second surface, visible, is a completely black with a lateral hole. Whit the free rotation of the two surfaces we will be able to vary the phases of the moon.

I think it is also a useful way to teach it to children.

If you liked this original way to discover our moon, comment it.
