Lunar Wheel was developed since when we were learning about moon phase, we didn't understand but so curious in it. We used The geometer's sketchpad to draw and simulated the orbit of the Moon. Then we made a planisphere-liked tool and called it "lunar Wheel",

​

Lunar Wheel can be used to estimate the position of the Moon at a particular time on a lunar date, and find the approximate time of Moonrise and Moonset. Teachers, students, children, and people can use it to learn about the moon phase, and get into the sky of astronomy and science.
