III.  GRADING SYSTEM:

A.  Attendance:

Regular attendance in all parts of the course is essential to achieve the course objectives.  An unexcused absence during a scheduled quiz or examination in any part of the course will result in a zero point score for that quiz or exam. There are no makeup quizzes or exams.

 

The reason for any excused absence from an exam, quiz, or laboratory session must be presented to your instructor (in advance if possible) and substantiated in writing with the student’s signature.  Emailed excuses are not enough.  Assignments and tests missed for a valid reason will not be counted against you, but you will be respon­sible for material covered in your absence.  Advance notice of a pending absence will often make it possible to arrange for an alternate time for a quiz, exam or attendance in another lab section.  If you miss more than one exam for any reason, you will receive an incomplete or a failing grade depending on the circumstances.

 

B.  Grade Distribution:                                                                         Points

4 Lecture Exams (4 X 100 pts.)....................................              400

Discussion Quiz (7 X 10 pts.)........................................                70

Discussion Worksheets ....................................................           80

Laboratory (9 X 15 pts + Quiz)......................................              150  

Total                           700

C.  Grading Scale:

Your final grade in the course will be determined by the total number of points you have accumulated according to the following scale.  This scale is only an approximation and the instructor reserves the right to change the points required if necessary.  Two unexcused absences from lab or unsuccessful completion of the laboratory component (<50% of available points) will result in a failing grade for this course regardless of how many points have been accumulated.

 

Grade for total points accumulated:

F:  0-349 (<50%)       D: 350-426 (50%)    CD:  427-441(61%)    C:  442-497 (63%)  

BC:  498-525 (71%)  B:  526-594 (75%)   AB:  595-608 (85%)   A:  609-700 (87%)

D.  Laboratory Grade:

In the past, traditional “cook-book” laboratory exercises have been employed.  Our experience suggests that these experiments fail to evoke significant critical thinking, and students report that the experiences are irrelevant, boring and do not clearly connect between the lecture and the laboratory experience.  To address this apparent shortcoming, this laboratory will emphasize investigative activities in extended laboratory exercises.  Each laboratory meeting will be graded on a 15 point basis.  The 15 points awarded for each laboratory will be split between a grade on your pre-lab assignment, record-keeping (your notebook) and a written summary of your results, which will differ for each lab.  You will lose points for not showing up on time, not contributing to your team, not working safely, not wearing goggles, etc. 

 

Two unexcused absences from lab or unsuccessful completion of the laboratory component (<50% of available points) will result in a failing grade for this course. You may attend another lab during the same week to make up a missed lab.  Please contact the instructor ahead of time.

E.  Discussion Grade:

Attendance at discussion is mandatory and you are expected to attend the section for which you are registered.  Any long range schedule conflict must be resolved with the course coordinator.

 

Weekly problem assignments are to be completed before attendance at the discussion period.  Any questions you may have should be asked before discussion; e-mail the instructor, stop in the instructor’s office, ask a tutor, ask another student, attend the workshop.

 

A ten (10) point quiz will be given during the first part of each discus­sion period.  It will be a problem (or problems) similar to those assigned for that week.  Your best 7 quizzes, out of 8 possible, will be used to compute your Discussion quiz grade (10 points possible on each quiz).  Unexcused missed quizzes will result in zeroes being entered into your quiz average.

 

The rest of the discussion time will be spent working in small groups on worksheets provided by the instructor.  Each worksheet is worth 8 points, and you can accumulate up to 80 points for the worksheets.  Material on the worksheets will not be covered in lecture, but will be on the exams. 

 

If you know you are going to miss a discussion, please contact your instructor.  You may be able to attend another discussion section to make up the work.

 

 

IV.  COURSE POLICIES:

Misgraded quizzes or exams must be returned to your instructor for possible re­grading no later than one week following their return.  You should save all tests, quizzes, and lab reports so that you will have them available for review, and so that any chance of clerical error may be avoided.

 

It is YOUR responsibility to check D2L for the exam scores, quiz scores, lab scores and discussion points to determine that your scores were entered properly.  Any error must be re­ported within a week of the posting date in order for it to be con­sidered.

 

No radios, tape players, headsets or other recording or transmitting devices may be used during exams.  Caps with bills must have bills turned to back of head.  A student ID card is required when handing in exams.

 

Early exams will be offered for students who cannot attend the evening exams.  Students who need to take an early exam must sign up with the instructor the week before the exam.  Students taking an early exam will not be allowed to use a calculator with memory capability.  You must either bring a simple calculator of your own, or use one provided by the chemistry department. 

 

Lecture examinations will be computer scored and the answer sheet will not be returned to you, but retained by the lecturer for a permanent record.  Answer keys will be posted on D2L and on the bulletin board outside HS‑403.

 

A WORD TO THE WISE:  The most common reason for a poor grade in this course is the failure to keep up with the work on a daily or weekly basis.  In gen­eral, if you attend all parts of the course, read the text, complete and under­stand the weekly problem assign­ments and lab experiments, you will pass the course (grade of C).  If you study in addition to that, you should do better.  If you experience difficulty with any part of the course, seek help immediately.  If you let it slide, it be­comes more difficult to catch up because the subject matter tends to be cumu­lative.

 

WORKSHOP:  A two-hour once-a-week workshop is offered on Mondays from 5:30-7:30.  This is a group problem-solving session during which you will work with other students to solve typical chemistry homework problems.  Student assistants will be available to answer questions.  This is not a tutoring session.   You must be willing to work with other students to solve the problems.  Room information will be posted on D2L.  The only charge is for a workbook that must be purchased at the bookstore.  

 

NOTE:  The last date to drop this course without a Late Add/Drop Request Form is October 17.  Students dropping the course must check out of lab before the drop is considered complete.

V.  COURSE OBJECTIVES

This course is intended to introduce the student to the language and the elemen­tary theories of chemistry, to provide training and practice in analytical reasoning and problem solving, and to serve as the basis for further studies in chemistry.  The lab portion is designed to provide training in the experimental techniques of chemistry, and to reinforce lecture material with concrete experience.

 

Specific areas in which the student is expected to achieve minimal competency by the end of the semester are the following:

 

FUNDAMENTALS ‑ scientific notation, significant figures, SI or metric system, dimensional analysis, names and symbols of common elements and compounds, basic definitions of important chemical and physical terms.

 

STOICHIOMETRY ‑ writing and balancing chemical equations, recognizing redox reactions, use of mole concept to perform calculations based on formulae and balanced equations.

 

ATOMIC STRUCTURE ‑ composition of the atom, electron configuration and quantum numbers, Aufbau procedure, periodic variation in chemical and physical properties, nature of nuclear reactions.

 

MOLECULAR STRUCTURE ‑ molecular geometry prediction by VSEPR, val­ence bond theory, hybridization, resonance, correlation of molecular structure and properties.

 

SOLUTIONS ‑ concentration units, solution stoichiometry.

 

INTERMOLECULAR FORCES-types of forces, relate to physical properties, solution formation

 

PRINCIPLES OF CHEMICAL REACTIVITY I - enthalpy, entropy, calorimetry, Gibbs free energy.

 

PRINCIPLES OF CHEMICAL REACTIVITY II - kinetics of 1st and 2nd order reactions, rate laws (not integrated), collision theory, energy diagrams, catalysts

 

PRINCIPLES OF CHEMICAL REACTIVITY III- equilibrium systems, Keq, LeChatelier’s principle, acid/base chemistry, pK versus acid/base strength, strong acid/strong base titrations, buffers
