The Department of Physics in its curriculum endeavors to provide a unified presentation of all the major areas in physics to fulfill the needs and interests of a variety of students. This presentation is set in a liberal arts context such that, in addition to the ideas, experiments, and theories, the philosophical and cultural implications of physics are considered.

The department offers a comprehensive major designed to prepare students for graduate study in physics, engineering, or related fields. The physics curriculum also provides for majors in teaching and interdisciplinary programs, as well as the physics component of pre-engineering and other pre-professional programs.

Through its offerings in the Liberal Arts Perspective Curriculum and the Three Crowns Curriculum, the department provides distinct courses for the general education of students who are not engaged in the natural sciences, but who would like to explore physics and astronomy.

It is important that students considering a major in physics begin their studies with PHY-195/196 in the fall of their first year. The normal sequence of courses through the first two years of the major would then proceed through PHY-205/206, PHY-215/216, PHY-225, PHY-230, and PHY-270/271.

Students preparing for graduate studies in physics or engineering are encouraged to take the following courses in addition to those required for the major/minor: PHY-300, PHY-350, PHY-360, PHY-370, PHY-380, PHY-390, and PHY-399. Also recommended is CHE-107.

### Physics Major:

10.25 courses in physics, including: PHY-195, PHY-196, PHY-205, PHY-206, PHY-215, PHY-216, PHY-225, PHY-250, PHY-270, PHY-271, PHY-305, and PHY-365.

PHY-195 and PHY-196 are the only Level I courses that shall count toward the physics major.

No Level II course graded below a C will count towards the major or as a prerequisite for subsequent courses.

No Level I or Level III physics or math courses graded below a C- will count towards the major or as a prerequisite for subsequent courses.

### Grades 5–12 Physics Teaching Major:

This major is only for students who have been admitted into the Minnesota licensure program to teach all areas of science in grades 5-8 and physics in grades 9 –12. It requires the core science and education courses for Secondary Education and also the requirements for the Physics major. The addition of six courses: GEG-125, GEO-111, PHY-102, PHY-100 (or PHY 120/122 AND PHY 170/172), EDU-396 and EDU-248 will add the 5-8 middle level science license to the 9-12 Physics license. (Note: PHY-100 is an IEX course and is offered occasionally in place of the two sequences of physics courses.)

Please see the Education Department section of this bulletin or the department website (gustavus.edu/education/) for a listing of the Education courses required.

### Grades 9–12 Physics Teaching Major:
