Classes

CHEM 102 Lab – A Laboratory for Organic and Biochemistry
CHEM 303 Lab – Organic Chemistry Laboratory I (Non-Chemistry majors)
CHEM 303 Lab – Organic Chemistry Laboratory I (Chemistry majors)
CHEM 304 Lab – Organic Chemistry Laboratory II (Non-Chemistry majors)
CHEM 304 Lab – Organic Chemistry Laboratory II (Chemistry majors)

CHEM 303 lab for non-chemistry majors will use the same lab manual in both Pocatello and Idaho Falls. Lab manuals will be available in both bookstores (ISU Bookstore and The University Place in Idaho Falls).You must attend the first lab, otherwise you will be dropped From the lab. Also, you must bring your lab manual when you attend the first lab. See the Lab schedule and please read the lab syllabus.

Syllabus

Laboratory Supervisor - Nuri Omar, Room 249, Physical Science, 282-4707
Lab instructors all have boxes in the Chemistry Department Office for leaving messages.
Office hours and study room assignments will be posted for Mr. Omar.

You will need:

Disabilities

If you have a diagnosed disability or believe you have a disability that may require reasonable accommodation on the part of ISU, please contact the Center for Students with Disabilities. You must contact this office and obtain a letter of authorization before any arrangements can be made. "Our program is committed to all students achieving their potential. If you have a disability or think you have a disability (physical, learning disability, hearing, vision, psychiatric) which may need a reasonable accommodation, please contact the ADA Disabilities & Resource Center located in Graveley Hall, Room 123, 282-3599 as early as possible."

Safety

Laboratory courses in chemistry of necessity involve the use of chemicals whose toxicity may not be completely understood. Exposure to chemicals in all laboratory courses is kept at a minimum and deemed to be safe when used as intended. The effects of materials used in this course on individuals with special health conditions or on fetal development are less well understood. Therefore such students should contact Mr. Omar after consulting with his/her physician and before enrolling in this laboratory course.

Pregnancy

If you are pregnant and you want to take the lab, please obtain a written letter from your doctor. We do not know the effect of some of the chemicals that are used in the labs on the fetus or the baby. However, we strongly advise you to take the lab another time when you are not pregnant.

Course expectations

General Chemistry or the equivalent of Chemistry 111-112 is a prerequisite for this course. It is expected that you understand and possess mastery of concepts such as pH and acid-base chemistry, stoichiometry and unit conversions, ionic reactions, molecular weight, density, mass and volume measurements, balancing equations, theoretical and percent yield calculations and oxidation-reduction, etc. This is an organic laboratory course. As such the focus will be two-fold, beginning with the introduction of typical laboratory skills. This involves performing experimental techniques and understanding the principles and use of instrumental methods, topics which may or may not be discussed in lecture. Following directions written in scientific vocabulary,making observations and recording-keeping are skills which can only be learned by doing. Typical organic reactions which have been or will be discussed in lecture will be performed. An attempt is made to co-ordinate experiments with topics in lecture. Considering that there are different lecture sections with different professors, you should expect either to review a reaction in your text that your section might have already covered or to read ahead in anticipation of a future lecture topic.

You are expected to be on time to lab and to have read assigned material before coming to class. It is expected that a mature respect for the instructor and other students will be shown in the laboratory. Possessing a positive learning attitude will make your lab experience more enjoyable and more rewarding for all concerned. Ask questions! The laboratory setting is less formal than the lecture setting, and thus learning from peers as well as the instructor is encouraged. However, it is expected that each student will be responsible for his/her own work and have a high sense of integrity.

Reports

Each week you will keep a record of experimental work in your Experiment Book by using the report sheets included at the end of each experiment. Pre-lab or post-lab questions, for example those at the end of each experiment, may be assigned. Always read the student directions for these assignments and other announcements! The experiments are designed to be completed in the 3 hour lab period, assuming that students are prepared to begin work promptly and to work efficiently.

Some experiments will be performed in pairs with one report to be handed in. In this case, both individuals should be sure that their names appear on the report. Both will receive the same grade. Some experiments will be performed and graded individually. The report conclusion must be typed on a separate piece of paper or you will lose 5 points. Reports will be due at the beginning of the following week lab. A 10% per day late penalty will be assessed for late reports or assignments.

Exam and Quizzes

Unannounced pop quizzes will be given during the first 15 minutes of the lab. There will be no make-ups for late arrivals. Unannounced quizzes will cover the scheduled experiment. Much of laboratory work involves being able to follow directions and learning "hands-on" skills. However understanding the principles behind these directions demonstrates that a student has attained a perspective on the material, so that this knowledge may be applied in a new situation. consequently, exams will not only test specific topics dealt with in the experiments, but will target the application of these principles and laboratory techniques to new but related situations. There will be one comprehensive exam at the end of the semester.

Grading

From the ISU Catalog:

A letter grading system is used to describe the instructor's evaluation of a student's performance in each course:

A  = 93-100%
A- = 90-92%
B+ = 87-89%
B  = 84-86%
B- = 81-83%
C+ = 78-80%
C  = 75-77%
C- = 72-74%
D+ = 69-71%
D  = 66-68%
D- = 63-65%
F  < 62%

For Chemistry 303:

Weekly reports = 55% (complete, legible)
Quizzes = 25%
Final Exam = 20%

In order to earn an "A" in lab, excellent experimental work is required as well as a mastery of the concepts involved. Corrections to graded papers must be requested within one week following their return, and a complete regrade will be done at the instructor's discretion. NOTE: Be aware that the grade for this course is separate from the lecture grade. A letter grade is based on the total percentage of weekly reports and quizzes.

Dropping the course

If you decide to drop the course, you must clean your equipment and check out. If you do not do this, you will be assessed a fee by the stockroom.

Absences

Laboratory work is a "learning by doing" situation! Consequently, absences are highly discouraged.

If you must miss an experiment because of an emergency (personal or immediate family emergencies only), you are still responsible for understanding the techniques and procedures.

If you know ahead of time that you must miss your lab, you may try to attend another section. One such request per semester, in writing, will be considered by Mr. Omar, if lab space permits.

There will be no make-up lab. If a lab is missed for a valid reason, your grade will be determined on the class average of the experiment you missed. A second missed experiment will result in a "zero." Three absences will result in a failing grade in the course. A missed quiz will be given a zero grade.
