An interactive simulation of Earth's seasonal dynamics that includes the axial tilt and other aspects of Earth's annual cycle.
This is part of a larger lab from the University of Nebraska at Lincoln: http://astro.unl.edu/naap/motion1/motion1.html
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness. Read what our review team had to say about this resource below or learn more about how CLEAN reviews teaching materials
Easy-to-use, intuitive simulation that, with minimal guidance, can complement other activities around seasonal dynamics.
The simulator and short investigations that are part of the lab may help users appreciate the complex dynamics of Earth's orbit as an important aspect of understanding Earth's climate.
This simulation is part of a larger lab that covers terrestrial coordinates and the celestial equatorial coordinate system, allowing users to explore the motion of the sun and how it relates to seasons.
If you need more information, see Student Guide dealing with the simulator and two activities that use it--Rotating Sky and Motions of the Sun--at [link http://astro.unl.edu/naap/motion1/motion1.html].
Make sure to note the lack of scale to students.
