Where is That Moon?

Planispheres have been around for generations, guiding users through nightly and seasonal starfields, so why is it only now* that a Moonisphere has come into existence? There are of course the more nerdish " rel="nofollow MoonStick (I love it!) and " rel="nofollow LunaWheel for calculating the phase of the Moon on specified dates, but this new Moonwheel is meant to help with more entry level questions. The Moon Gazers' Wheel, to use its full name, is an easy way to understand the phases of the Moon and plan when to find it in the sky. Some amateur astronomers may think that this is an unnecessary tool, but in fact understanding the phases of the Moon is almost deemed too hard to understand by some. A famous " rel="nofollow video asked graduating Harvard students to explain the Moon's phases and many could not. The Moon Gazers' Wheel is aimed at teachers and school kids who want to learn the relationship between the shape of the Moon, and the time of day or night. The wheel's creator, Bob Crelin, has also written a lovely children's " rel="nofollow book explaining phases, but his Moon wheel stands alone, and may finally teach kids (and their parents and teachers) about the movement of that marvelous satellite around our globe.
