This simulation-based teaching module illustrates three different, but related concepts. Terrestrial coordinates and the celestial equatorial coordinate system are both simulated, allowing students to explore the motion of the sun and how it relates to seasons. Interactive maps display terrestrial and celestial equatorial coordinates; students can change the point location on the map and view coordinates from different reference points. The third component of this package explores Earth's seasons and the ecliptic as the earth orbits the sun.
This module is part of a larger collection of simulation-based labs for introductory astronomy.
This resource is part of a Physics Front Topical Unit.
Unit Title: Astronomy Resources For the High School Classroom
In this module, you'll find simulations for introducing terrestrial coordinates (latitude/longitude), celestial equatorial coordinates, and how Earth's seasons are related to its axial tilt. It will help build a foundation for understanding obliquity, the angle between an object's rotational axis and a line perpendicular to its orbital plane. Knowledge of obliquity is crucial for astronomy calculations and Earth-based observation. Includes detailed student guide, assessment materials, and background information.Link to Unit:
