I originally built these models a couple of years ago, but didn’t realize it was something “novel” until I got some comments at this past year’s NEAF where I had brought them for the children’s section. Quite frankly, I think it works well with adults, too, as I’ve heard some well-educated adults propagating common misconceptions about what causes the phases of the moon. The idea is simple enough. One side of the moon is illuminated by the Sun, the other is not. As the moon goes around the Earth, the relative geometry of the Earth, Moon, and Sun changes, but the half of the moon facing the Sun is always illuminated and the other half is not. So, we create a 3D model where you can put your head in the place of the Earth and look at the moon at different positions in its orbit. Here’s my son Matthew modeling the model.
