Philosophy of the Course:

 

Science concepts courses are intended to provide a broad and useful introduction to various science areas for students not majoring in science or technology. The course is designed to teach the student about nature and the physical universe as it is presently understood by modern, mainstream scientists.

 

Physical Science Concepts is designed to stimulate your interest and improve your understanding of a variety of related subject areas in the broad realm of Physics and Chemistry.  Factual material will be presented with considerable discussion of the technological developments, political concerns, and sociological consequences of the topics considered.  A historical perspective will be important to our understanding.  It is hoped that your curiosity concerning scientific endeavors and your concern for their consequences will be enhanced.  Ten years hence, when you have forgotten many of the specific facts, you may retain a new outlook on the world.

 

Quizzes and Examinations:

 

Laboratory quizzes will be given in tha laboratory. No make-up quizzes will be given.  Each quiz will consist of five multiple choice questions based upon the labs completed in the previous week.  If the laboratory was missed, or not made up, it is suggested that as much of the laboratory be completed as is possible (at home and with the help of your laboratory partner) before the quiz is taken.  Your lab instructor can also be consulted for help.

 

Two hourly examinations will be given during the semester.  Specific dates and locations for these examinations will be announced at least one week in advance.  It is your responsibility to be present at all the examinations and the final examination.  The course final examination will be comprehensive and will occur in the 16th week of the semester.  An unexcused absence will constitute a zero score on any exam or quiz.  This will automatically occur if the course coordinator is not contacted within 48 hours of a missed exam, or beforehand if that is possible (eg. illness).

 

If you read the objectives and Study Questions, you should be able to figure out most of the questions that will appear on exams.

 

You must have your ID card and schedule to take a quiz or exam.

 

Laboratory Manual and Reports:

 

The Laboratory Manual, along with your data, results, graphs, diagrams, and answers to questions will constitute a useful text and guideline for the course, quizzes and examinations.  The laboratory reports will be collected weekly and graded (5 points each).  They are due immediately at the end of the laboratory in which they are performed.  None will be accepted later.  They will be graded and returned in the following class so that you have them to study for the quiz. A student who arrives late may not be allowed to participate in the laboratory.

 

 

Mercer's Academic Integrity Policy:

 

Academic integrity is violated when a student:

Violators will be penalized in accordance with college policy.READ the MCCC booklet on Academic Integrity.

 

Guidelines for Courtesy and Respect:

 

I would like to welcome all students into an environment that creates a sense of community, pride, courtesy and respect. In order to do this, please make every attempt to come to all classes, to come on time, and to stay until the end of the meeting. There may be a time when you are unavoidably late for class. In that case, please come into the room quietly and choose a seat closest to the entrance. Please turn off all cell phones and beepers prior to coming into class.

Once a class session has begun, please do not leave the room and then re-enter unless it is an emergency. If you miss a class meeting for any reason, you are responsible for all material covered, for announcements made in your absence, and for acquiring any materials that may have been distributed in class.

It is important that we are all able to stay focused on the class lecture/discussion. For this reason, only one person at a time in the class should be speaking. Side conversations are distracting for surrounding students and for me. As you can see, simple norms of courtesy should be sufficient to have our class run in the best interests of all of us. Thank you in advance for your cooperation.

 

Study Questions:

 

You should complete the Study Questions at the end of each unit after that unit is completed in lecture.  These will be reviewed in the laboratory period as indicated in the schedule.  Bring them to the laboratory in which they will be reviewed and receive 2 points for each set you have completed.

 

Additional Materials:

The videos shown in lecture support the lecture concepts.  If you miss one you can make up this material by requesting the videos at the Film Library.  You should be reading in On Giants' Shoulders:  Great Scientists and Their Discoveries  by  Melvyn Bragg all semester long as indicated in the Topical Outline.  Some questions on the examinations will be taken from this book, including items not mentioned in lecture. There are also available many study aids in the Library Computers, the computer laboratory (2nd floor MS), and the bookstore.

 

Help is also available in the Science Learning Center (MS 211).

 

Free tutors are also available in the Tutoring Center (second floor Library).

Guidelines

 

  1. The report should be exactly two double spaced typewritten pages, not including references.
  2. Reports will not be graded if:
  1. An exact due date will be announced; it will occur approximately during the tenth week of class.  Late papers will not be accepted.
  2. Topics will be suggested, both in writing and verbally, but it is best if you select a topic of personal interest to you. Be sure to get approval for your topic from the instructor in the course before the approval deadline. Please do not do a book report or a biography, they will not be accepted.
  3. The textbook may be used as a reference, but other sources must be consulted.  The bibliography at the end of each chapter might be helpful to you.  Your paper must include a bibliography of all sources that you used.  Consult the MCCC Student Guide to Writing Papers.  Encyclopedias are not acceptable references.  You must use at least 2 non-internet references.
