This course is the first of a two‑semester sequence that satisfies the Core Curriculum Natural Science requirement. It is also an ND (Numerical Data) course. This course usually covers solar system astronomy‑‑planets, the moon, comets, meteors, and some basics‑‑light, optics, and telescopes. We may elect to deviate from this approach somewhat, based on items of current or topical interest. This course is a prerequisite for AST 1002, which covers solar, stellar and galactic astronomy.
Students with special disabilities are invited to disclose special needs to the instructor.
Homework exercises are to be done first on scratch paper and then neatly copied, in pencil, onto the paper provided, and turned in at the beginning of the class session on the due date. Messy work or folded/wrinkled/crumpled papers will receive a reduced grade.
Homework grading includes grammar, spelling, and correct use of math and significant figures. No credit will be given for homework turned in after it has been graded and returned.
Extra credit work is not assigned or accepted. This is because such work is usually done in lieu of the required work that has been assigned as part of a logically thought-out curriculum, and is thus illogical
