Portland Community College | Portland, Oregon

This is a pre-calculus introductory physics course for pre-medical, pre-dental, pre-chiropractic  and pre-physical therapy students and students working toward a degree.  Study topics include mechanical properties of matter, heat, waves, sound and light.  This course meets college transfer, Oregon Block Transfer and program requirements as listed above.

After completion of this course, students will
1) Apply knowledge of thermodynamics, sound waves, and light waves to explain natural physical processes and related technological advances.
2) Use an understanding of algebraic mathematics along with physical principles to effectively solve problems encountered in everyday life, further study in science, and in the professional world.
3) Design experiments and acquire data in order to explore physical principles, effectively communicate results, and critically evaluate related scientific studies.
4) 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.

Principles and techniques are presented through lectures and class demonstrations.  Students must register for lecture and one laboratory.  Laboratory work will be performed in order to clarify certain facts in the lecture materials.

At the beginning of the course, the instructor will provide a syllabus that details 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 write-ups, 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.

Specific evaluation procedures will be given in class.  In general, grading will be based on accumulated points from homework assignments, tests, a final exam, and labs.
