200 | 300 | 400 | Graduate Courses

Courses primarily for undergraduate students


Astro 102. North Star Astronomy. Cr. 1. F.S. An entirely WEB-based course covering topics in observing the sky and navigation by the stars for students with little or no previous experience. The course combines material on common naked-eye phenomena such as lunar phases and apparent motions of the stars and planets with information on how these helped navigators determine where they are on Earth. The course "lectures" are on-line, interactive units with build in exercises, hands-on (offline) activities and layers of help. Graded homework and quizzes are administered via Web-CT.

The solar system: origin and evolution; characteristics of the sun, planets, satellites, comets, meteorites, and asteroids. Extensive use of the planetarium is included.

Astro 125L. The Sky and the Solar System Laboratory. (0-2) Cr. 1. F.S. Prereq: Concurrent or previous enrollment in Astro 120. Laboratory course to accompany Astro 120. Students carry out practical exercises involving naked eye and telescopic observing to explore and reinforce ideas covered in Astro 120. Activities based on a sky-simulation computer program and other computer- based exercises are also included.

Astro 150. Stars, Galaxies, and Cosmology. (3-0) Cr. 3. F.S. For the nonscientist.
