Time-Lapse Seasons Interactive
This interactive simulation/movie allows students to watch the changing altitude of the sun at noon throughout the entire year. Along with the simulation is a time-lapse video showing the changing shadow of a large building, and the changing seasons outside.
This interactive is used to demonstrate how the changing declination of the sun directly impacts the change of seasons on earth. It is used (along with several other interactives) in this teacher video (http://media.mivu.org/mivhs/astro/2-3b/2-3b.html)
