TEXT: Macaulay, David (1998). The New Way Things Work. Houghton Mifflin Company: Boston, MA.

Valadares, Eduardo de Campos (2006). Physics, Fun, and Beyond. Pearson / Prentice Hall: Upper Saddle River, NJ.

ATTENDANCE: "Milligan College makes no provision for a system of allowed absences, sometimes called "cuts." The student is expected to attend each meeting of the classes in which he or she is enrolled. Absence from a session of the class involves a loss in learning opportunity for which there is no adequate compensation. The teacher’s evaluation of the work done by the student is necessarily affected by such absence. Penalties for absences have been adopted by each area and are stated in individual class syllabi." [From Milligan College Catalog]

Attendance will not be recorded in the lecture portion of the class. We do however make a mental note of those students who are missing class and consider this in the final assignments of grades. Hopefully, you will make a choice concerning class attendance which will promote your success in the course. We do not consider it our responsibility to present lecture material a second time when you have chosen to absent yourself from lecture.

Makeup work (without penalty to the grade) will be allowed only when students must be absent for the purpose of (1) participating in a school sponsored trip, (2) attending the funeral of a family member, or (3) confirmed personal illness. The makeup work must be completed within one week following the return to class. The student is responsible for informing Dr. Junker of impending absences and arranging for any necessary make up work prior to the absence. This Makeup policy applies to lecture and laboratory!

WRITING ASSIGNMENTS: Writing assignments will be in a variety of formats including chapter / concept summaries, or responses to television shows & magazine articles. The assignments will be given out in class (and posted on Angel) with the due dates. The assignments should be typed, printed out, and handed in before lecture begins. Each of these assignments is worth 10 points – no late work will be accepted (so if you are going to miss class, send your work with a classmate).

A research paper will be assigned as part of the writing assignments portion of your grade. A list of acceptable topics will be given out in class. You must inform Dr. Junker of your choice of topic for approval (to eliminate duplicate choices within the class). You will present your findings to the entire class during lab on March 27^th. A format for the paper will be given to the students to use in planning their papers and what information should be gathered. The paper and presentation will be worth 50 pts.

EXAMS: Four unit exams will be given. The exam format will mainly consist of multiple choice, fill-in-the-blank and discussion sections.

LABORATORY: The laboratory is an essential part of the course which both illustrates and supplements the classroom instruction. Attendance is REQUIRED. You may be excused from laboratory only for the reasons given under the attendance paragraph! Lab reports are due on the Tuesday immediately following the lab. They should be typed, printed out and handed in before lecture begins on Tuesdays.

If you have missed lab, you can make it up after receiving permission from Dr. Junker and scheduling the makeup time with her. An AUTOMATIC FAILURE in the course will result if ALL LABS are not COMPLETED AND A LAB REPORT HANDED IN.

Safety glasses may be required for certain experiments in the laboratory – they are provided by the College.

The following format will be required for labs:

(1) Your Name (4) Group Members

(2) Name of Lab (5) Observations & Data for each experiment and demonstration

(3) Date lab performed (6) Summary of entire lab

GRADING: 4 Unit Exams 150 pts. each x 4 = 600 pts. (= 60%)

Writing Assignments 150 pts. (= 15%)

Labs 250 pts. (= 25%)

TOTAL 1000 pts. possible (= 100%)

Your final grade will be determined by using your total percent average against the following grading scale:

	B+ 87.0 – 88.9	C+ 77.0 – 78.9	D+ 67.0 – 68.9
A 92.0 – 100.0	B 82.0 – 86.9	C 72.0 – 76.9	D 62.0 – 66.9
A- 89.0 – 91.9	B- 79.0 – 81.9	C- 69.0 – 71.9	D- 59.0 – 61.9

DRESS CODE: In keeping with the admonishments found in the scripture regarding modesty in dress, dress must be appropriate for both lecture and laboratory. In general, no bare midriffs, no low-cut tops, no bare shoulders, no “short” shorts. For laboratory, dress so that you are free to move comfortably without interference or hindrance from clothing and jewelry.

COURSE DESCRIPTION: A course which investigates the application of basic physics principles in the objects around us. Topics include levers, gears, digital technology, waves, and electricity. Offered as an exploration of student interest and coverage of applied physics principles. Three hours lecture and one two-hour laboratory per week. Four semester hours.

Note: Fulfills the General Education Requirement for a Laboratory Science course.

COURSE OBJECTIVES: Upon successful completion of this course the student will:

1. Begin to see science in everyday life.

2. Learn that science isn’t frightening.

3. Learn to think logically in order to solve problems.

4. Develop and expand his/her physical intuition.

5. Learn how things work.

6. Begin to understand that the universe is predictable rather than magical.

7. Obtain a perspective on the history of science and technology.

8. Be able to summarize the basic principles of physics as applied in common household and working environments.

Writing Up a Lab Report for Physics 295

NAME

PHYSICS 295 LAB

DATE Lab Performed

Members of Group: _______________, _______________, ________________ (list names)

DATA:

Expt. Title [and # (if from your lab manual)]

Describe what you did (can include a table if have results to show) and what you saw.

Answer questions asked in the lab manual.

Include all the experiments and tasks you were given to complete in the lab. If there was a demonstration, that too is included in your lab report. Some of these will be on handouts or just simply described when you come to lab.

SUMMARY OF ENTIRE LAB:

Talk about what you learned in the lab. What principles were demonstrated? Talk about applications of the principals in the gadgets, instruments, etc. that you worked with.

Notes:

All lab reports must be typed, printed out and turned in before lecture begins (12:39 p.m.) on the Tuesday immediately following the Thursday lab. Please set on the table at the front of the classroom or hand to Dr. Junker. You may hand draw your illustrations when included in the write up.

LAB RULES:

Absolutely no food or drink in the laboratory.

Do not wear clothes with pieces that hang loosely.

Only perform the labs that are assigned.

If any accident happens, inform one of your instructors immediately.
