The department offers two majors. The major in astronomy is specifically designed to train students in the field of planetarium edu-cation; it also may serve as a basis for earning state certification as a secondary school teacher of general science. The major in physics can prepare students for graduate work in physics, astronomy, and related physical sciences, for the cooperative program in engineering, for state certification as secondary school teachers of physics, or for technical positions in industry.

Astronomy (ASTR)

The major in astronomy requires courses in astronomy, physics, chemistry and mathematics. The required courses are ASTR 111, 448, and five additional courses numbered ASTR 112 or higher four of which must be numbered ASTR 230 or higher; PHYS 225-226; two courses in chemistry to be selected from CHEM 110, 111, 330, 331, or 439; and MATH 128-129.

Astronomy majors are also required to register for four semesters of ASTR 349 and 449 (non-credit colloquia)

The requirement for taking ASTR 448 can be satisfied by doing an individual studies or honors project where the results would be pre-sented at a departmental colloquium. A double major in astronomy and physics need only take the course once. Students participating in an engineering 3-2 program will be exempt from taking ASTR 448. Students who have success-fully completed a summer REU, RUG, or equivalent research experience may request departmental approval to substitute that experience plus an additional advanced astronomy or physics course not already required by the major in place of ASTR 448.

The following courses are recommended: PHIL 223 and 333, PHYS 333, and Art 227.

Students interested in teacher certification should refer to the Department of Education on page 99.

The following course, when scheduled as a W course, counts toward the writing intensive requirement: ASTR 230.
