Course Description

Introduces waves and sound, electricity and magnetism, and light and optics. Designed as a laboratory science course for non-science majors. Prerequisites: (WR 115 and RD 115) or IRW 115 and (MTH 65 or MTH 98) or equivalent placement. Audit available.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Apply knowledge of sound waves, electricity and magnetism, and light to explain natural physical processes and related technological advances.
  • Use an understanding of elementary mathematics along with physical principles to effectively solve problems encountered in everyday life, further study in science, and in the professional world.
  • Design experiments and acquire data in order to explore physical principles, effectively communicate results, and critically evaluate related scientific studies.
  • Assess the contributions of physics to our evolving understanding of global change and sustainability while placing the development of physics in its historical and cultural context.

Quantitative Reasoning

Students completing an associate degree at Portland Community College will be able to analyze questions or problems that impact the community and/or environment using quantitative information.

General education philosophy statement

PHY 103, which delves into a conceptual understanding of physics, enlightens the student of their natural and technological environments. It adapts the learner to reason both quantitatively, through manipulating mathematical formulas, and qualitatively, through piecing together scientific laws. And, in this process, the learner will slowly acquire the skill to conceptually organize theoretical knowledge and experiential observation to formulate their own truths.

Outcome Assessment Strategies

At the beginning of the course, the instructor will detail the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, laboratory reports, research papers, small group problem solving of questions arising from application of course concepts and concerns to actual experience, oral presentations, or maintenance of a personal lab manual.
The student will be evaluated on written tests covering both lecture and lab experiences, required lab reports, and on turned-in homework questions (verbal skills and reasoning in written format) and problems (quantitative in a few cases).
