This simulation has been selected for inclusion in the CLEAN Collection based on the following review comments:
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
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 http://astro.unl.edu/naap/motion1/motion1.html.
Make sure to note the lack of scale to students.

TEACHING NOTES / CONTEXT FOR USE
About the Science
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.
About the Pedagogy
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.
Technical Details/Ease of Use
Easy-to-use, intuitive simulation that, with minimal guidance, can complement other activities around seasonal dynamics.
Assessment is at the discretion of the educator and how this resource is applied and the expectations.
