Description

With this app, you can learn visually about the waxing and waning of the moon based on the positions of the moon, earth, and sun.

The upper screen is a chart of the celestial sphere from which you can check the positions of the sun and moon as seen from earth.
Change to "tracking" mode to see from the perspective of a person looking at the moon. Move the slider to change the angle of the celestial sphere.

The lower screen is a chart from which you can see the relationships between the positions of the moon, earth, and sun.
(To allow for easy understanding, sizes and distances are different from actual proportions.)
The moon as seen from earth at the current time is shown in the top left. Move the slider to change the angle of the figure.

*The celestial sphere chart shows the perspective from the northern hemisphere (around Japan).

Ratings and Reviews

Good start, usable, but still needs more development

It is a good learning tool to start a lunar discussion, however, kids get pretty bored just watching the app make the orbits. To improve, they need to allow the user to select dates and/or times to predict and tie information together. Also, a zoom function would help.
This was pretty good through the big LED projector.
So, this is a good beginning, and I used it in my 7th grade classroom, but to be more powerful than one day...keep going this could be really good.
