Report on the construction of a moon phase model for the visualization of the different moon phases and their formation <\/p>\n\n\n\n

The moon appears in the sky in different forms over the course of a month: once as a crescent shape, then a crescent moon and finally a full moon. Then again a crescent moon, crescent moon and finally a new moon. How do you explain the formation of these moon phases to someone who is interested?<\/p>\n\n\n\n

At our Sternstunden <\/strong><\/a>we usually use a flashlight as a sun and illuminate a ball as a moon that you carry around in a circle. Depending on the location, you can then see the phases of the moon ... depending on the location? That's the catch: If you stand outside the circle, you always see the half-illuminated moon. Only if you stand inside the circle (on the Earth's position) do you perceive the moon phases.<\/p>\n\n\n\n

Therefore, the idea arose to build a model that allows the viewer to experience the view from Earth. Here are my ideas\/specifications:<\/p>\n\n\n\n
