ASTR 122 - ASTRONOMY
Description:
This course is a study of the universe from the earth,
moon, and planets to the stars and the most distant
galaxies. Topics include black holes, quasars, the origin
of the universe and the possibility of life on other
planets. Current astronomical discoveries are discussed
in class as they occur. Access to astronomical Web sites
is available to students in this course. 3 hrs. lecture,
2 hrs. lab/wk., 5 nighttime telescope sessions are
required. Supplies: Refer to the instructor’s course syllabus for details about any supplies that may be required. Prerequisites: NONE Textbook(s): For information see - http://bookstore.jccc.net Course Fees: NONE Course Objectives: Upon successful completion of this course the student should be able to:

Indicate the possibilities of visiting or communicating with another civilization. Methods of Evaluation of Competencies: Evaluation of student mastery of course competencies will be accomplished using the following methods: Graded work for the course will include at least four unit tests, a cumulative final exam, at least 12 weekly laboratory exercises, night-sky observation, and a combination (determined by the individual instructor) of homework, lecture quizzes, written article summaries, and an article quiz. The percentage of the total grade allotted to each of the above kinds of course work will be within the following ranges: Grade Work Percentage of Course Grade Tests 35 - 50% Observation, Quizzes, Homework 15 - 25% Laboratory Exercises 10 - 20% Articles 5 - 10% Final Exam 15 - 25% Total 100% Caveats:
