Students use a simulator to better understand how the positions and motions of the Earth and moon create seasons.
Students use a simulator to better understand the phases of the moon as well as the geometry giving rise to them.
The NAAP Motions of the Sun Lab reviews some of the material from the Basic Coordinates and Seasons Lab and The Rotating Sky Lab and adds information to put all the pieces together for a more complete description of the motions of the sun. Computation of meridional altitude and stellar visibility are also introduced.
This simulation explores the sun/Earth connection. It allows variables to be manipulated such as time of year, latitude, angle, annalema, and declination, in teaching seasons.
