Chemistry 151 SAMPLE SAMPLE SAMPLE Fall 2000
GENERAL CHEMISTRY I
INSTRUCTOR: Dr. Kevin D. Crawford
Office: Byrd 315
Phone: 953-7787
CLASS MEETINGS: Lecture - Monday, Wednesday, Friday, 8:00-8:50, Byrd 301
POSTED KEYS: Homework, Small Group Exercise, and Exam keys will be posted outside my office.
OFFICE HOURS: M 11-12, T 9:30-10:45, W 9-10 and whenever my office door is open and I am not busy.
ATTENDANCE: Attendance at each class period is mandatory, and punctuality is expected. Advance notice of unavoidable absences is required. I will only authorize make-up exams under very special circumstances. Examples of excusable absences include infirmary visits, court dates, funerals, etc. GUARD DUTY DOES NOT EXCUSE YOU FROM A SCHEDULED EXAM. Whenever possible, arrangements should be made in advance for absences. Excessive unexcused absences will be dealt with at my discretion (in addition to any other punishments incurred). The 20% rule applies - the sum of excused and unexcused absences may not exceed 20% of the class periods (9), or the student will fail the course.
CALCULATORS: Each of you should have your own calculator and be able to use it. You will not be allowed to lend or borrow calculators during a test.
FOOD, DRINK, TOBACCO PRODUCTS: These items are prohibited in Byrd Hall. Do not bring them to class and do not use them in the building.
TEXTBOOK: You must have the textbook General Chemistry, 10th edition, by Robinson, Odom, and Holtzclaw.
ACADEMIC HONESTY (HONOR CODE): I expect that you will only turn in work that is of your own effort. You may work in groups on the homework, but outright copying is unacceptable. Everyone must participate in the small group exercises. If you leave the class before your group is finished you will not receive credit for the exercise. Cheating on exams will not be tolerated.
GOALS AND OBJECTIVES:
1. To learn the fundamental principles of chemistry.
2. To develop skill in making mathematical calculations, particularly those used in the
application of chemical principles.
3. To gain an appreciation of the applicability of chemistry to daily life.
4. To expand a working vocabulary in both chemical terms and the english language.
5. To develop an understanding of the interrelationship between chemistry, the other
sciences, engineering, and the activities of society.
SYLLABUS CHANGES: In the event that we fall behind the syllabus schedule, there is one catch-up day scheduled at the end of the semester. In addition, the homework schedule will slide according to the current lecture. The exam schedule will not change, however the material covered by the exams will change accordingly.
HOMEWORK: Homework will be collected at the beginning of the next class period. Most assignments will come from the end of chapter problems in the text. The total homework points will be the equivalent of half of an exam.
SMALL GROUP EXERCISES: Occasionally I will end the formal lecture early. At this point we will divide into assigned groups of three or four to work on a short worksheet. The small group exercises will be formatted in a similar way to problems on the exam. They also give you a chance to work a problem from that days lecture before you leave the room. The total points for SGE’s will be equivalent to half of an exam.
EXAMS: The final exam will be cumulative. All other exams will be cumulative only as necessary to cover the current material. The material covered in lecture one class period before regular exams will not be covered on that exam, but will be covered on the next exam.
NOTE: ADHD and LD students who require special exam procedures must present documentation to me from Academic Support Services well before the first exam.
POINTS: The following point breakdown will be used to determine your course grade for Chem 151:
a. 4 exams at 100 points each 400 points
b. Homework totalling 50 points 50 points
c. SGE’s totalling 50 points 50 points
d. Final exam 200 points
-----------------------------------------------------------
Total 700 points
CO-REQUISITE: Chemistry 161 (laboratory) is a co-requisite for this course. If you withdraw from one, you must withdraw from the other. The grades for these two courses are SEPARATE. Do not expect your laboratory performance to influence your lecture grade or vice versa.
