GeoAstro Applet Collection

GeoAstro Applet Collection

Authored by Jurgen Geisen, this site has more than sixty-five Java applets. The interactive resources provide detailed solar and lunar data and the daily and annual path of the sun and moon for any location. More specifically, the collection has fourteen applets concerning the moon, and another twelve which solely describe sundials. Six other resources focus on topics such as: the Venus transit observer, phases of Mercury and Venus, geocentric motion and many more. The author has made an outline for instructors in the order he best feels the applets should be introduced. The plan consists of seven different parts and careful lists of the different topics each section. This is a great resource for effective interactive online learning.
