COURSE DESCRIPTION:
PHYS 102 is the second semester of a two-semester course in introductory physics for science majors/health career students. The topics covered are: Wave Motion, Electric Charge, Electric Current, Magnetism, Optics, the Nucleus and Quantum Physics. The class meets for four one-hour lecture periods and one two-hour lab each week.

PREREQUISITES:
PHYS101 (Physics-Mechanics/Heat, P1 900L) with a grade of C or better.

NOTES: Each week, students are required to do a lab. All labs are set by the instructor prior to class. Each lab is composed of four different parts: pre-lab questions, data taking, calculations, and conclusion drawing. Each part takes about 30 minutes, and the total lab time is two hours per week. All labs are traditional hands-on bench labs. In the laboratory experience, students are expected to use scientific methodology to formulate or evaluate questions, to make systematic observations and measurements, to interpret and analyze data, to draw conclusions, to test the given hypotheses, and to communicate the results orally or in writing. All lab data, interpretation, and error analysis uses linear least square fit to get the best results. Critical thinking, technology skills, problem solving skills, communication skills and cultural awareness are embedded in course work. Critical thinking skills are measured by rigorous homework problems including defining the problem, constructing a method for solution, and evaluating the results. Technology skills are embedded in the course, such as usage of both computers with current software, and tools used in making measurements. Technology skills are assessed by evaluating the accuracy of the lab results. Social skills are embedded in the course, in the form of teamwork, defining roles, planning projects, developing oral or written lab reports. Students are expected to assess and evaluate the effectiveness of teamwork by use of a rubric. The class web page is updated every week, which provides supplemental information such as announcements, lecture notes, homework assignment, and students' grades. Pre-lab questions, data taking, data analyzing, calculations, conclusion drawing are embedded in the face-to-face traditional lab periods.

TOPICAL OUTLINE:
PHYS 102 is a 16-week course. The following list is the time spent on each topic. Students who successfully complete the course will demonstrate the following outcomes by properly finishing their regular homework, presentations, quizzes, tests and a final exam. Students will construct graphs, charts, free body diagrams, interpret them, and draw appropriate conclusions. Students will communicate meaningfully in writing while presenting information and provide solutions with the procedure, results, organization, diagrams and other details necessary for another person to review. At the end of the course, students will be able to solve problem regarding to design and safety. Every week, students will actually do a group bench lab, which is composed of four parts: pre-lab questions, data taking, calculations, and conclusion drawing. For each lab, students are expected to use scientific methodology to evaluate questions, to make systematic observations and measurements, to interpret and analyze data, to draw conclusions uses linear least square fits to get the best results, to test the given hypotheses, to calculate the percent errors, and to communicate the results orally or in writing.

EVALUATION:

The classroom activity is a lecture-demonstration-discussion situation, involving the student directly with the material being presented. Homework is either collected or discussed in class. Homework exercises are about 75% numerical and 25% explanation-discussion. All the homework questions are selected from the textbook. The difficult level of the homework questions is similar to the examples discussed during the lecture period. 5-minute-long quizzes are given over each chapter or main topic. There are three major hourly exams. All the quiz/exam questions are selected from the Test Bank, which comes from the textbook publisher. Half of the questions are in multiple choice formats, while the others are in regular format. A 5-inch formula card and calculators are allowed during the quizzes/exams. Students are expected to spend about additional 5 hours outside the class to complete the homework assignment, to finalize their weekly lab reports and to prepare their quizzes/exams.

The final grade is determined by:
