EISCOIlluminated Sun, Earth & Moon Orbital Model, 12.25" H x 16.25" W - 12V Light Bulb Demonstrates Sunlight on Earth & Moon - Solar Eclipse Demonstration - Includes Experiment Guide

I used it to explain seasons to my 7th grade science class. I loved that the months were there to depict the sun's rays angles on the earth as it corresponds to the seasons.

I have used it for years, and it has held up well. It is a great way to demonstrate Moon phases and eclipses. Lots of people want to know where I got it and how they can buy one.

Just a little disappointed. Thought the rotation and revolution would be 'automatic' and included in the motorized part of this. But, I can also see this could be more useful. As I can start/stop as I wish. Without a motor. WOULD be nice if the moon would automatically revolve the Earth as the Earth revolves around the Sun.

Great model, well built. Yes there are limits to it, as there are to any model. But it’s very solid

Uh, Northern is spelled wrong on all four sections of the base….🙄 and the moon is too low so when you try to see a full moon, it’s an eclipse. Kind of a big miss.

super cool love it

Because the moon in this model is always in the ecliptic (not tilted or even elevated with respect to the earth-sun orbit), the full moon position is always a lunar eclipse, i.e. you can not demonstrate a full moon. Further, the geometry of the model is such that quarter moons (when the light bulb rays are perpendicular to the earth-moon viewpoint) occur too early with respect to the new moon position. These two things (especially the first point) make explaining moon phases more, not less, confusing to kids (and adults). Making this all worse - none of this is explained in the accompanying guide book.
