Student Class Schedule cards DO NOT indicate the correct room for the CHE 108 laboratory sections. All laboratory instruction begins in the recitation room with a pre-laboratory discussion of procedures and safety precautions before proceeding to the laboratory. CHE108 laboratory sections begin at the same time and in the same room as the scheduled recitation with which they alternate. The lab instructors will inform their students which laboratory room in the Natural Sciences Complex (NSC) has been assigned to their section. Safety regulations require that laboratory aprons, monogoggle safety glasses, long sleeve shirts, full length pants and shoes that cover the entire foot be worn for all lab work. Students not properly dressed to complete lab may leave to change, noting that the laboratory will end at the scheduled time. Failure to comply with any safety regulations will result in the student leaving the laboratory, with a grade of 0 (zero) for that day's laboratory work. All materials are required at laboratory check-in and check-out. Students are expected to read the experiment of the day and view the posted digital video about the laboratory before the pre-laboratory discussion. CHE 108 students are to submit a handwritten flow chart as well as the answers to the pre-lab questions in a legible form and hand them in to their lab instructor at the beginning of pre-laboratory discussion on the day the experiment is conducted. At the conclusion of the lab period, after cleaning up their station, students are to turn in their data sheet and have their instructor initial their lab book. The write-up of the experiment, using the pages in the lab manual, is due at the next lab meeting and should be turned in prior to the pre-lab discussion. Originals only. Photocopies will not be accepted. Student I.D. cards must be obtained and used to check out certain laboratory equipment at the stockroom. Direct any questions about lab work to the Laboratory Director, Mrs. Clarke. A laboratory safety awareness test has been scheduled for all recitation/lab sections. The test will be given during the recitation periods held Monday, February 4 th - Thursday, February 7 th. Students should read pages 15-21 (Lab Rules and Regulations, Laboratory Safety and Safety Precautions) in the lab manual) to prepare for this test. Students missing more than two questions on the lab safety test will be required to repeat the test. Lab Check-out and Improper Lab Check Out Charge: All students must check out of their lab drawer during their regular lab period (with their lab instructor) during the week of check-out (May 6-9, 2019). Those who do not are subject to a $100.00 check-out charge plus charges for broken, missing or unusable equipment as well as having the lock cut off the drawer. (Safety glasses and lab kits will be held in the stockroom for one month only). Students who drop the course during the semester must check out within one week of dropping to avoid the lab check-out charge. Students who are absent from check-out at the end of the semester because of illness must complete a waiver form, available at the Copy Center (NSC 361) to have this $100.00 charge waived. This form requires written documentation from a physician verifying the reason for the absence. Filing for a waiver is the student s responsibility alone, and the decision on a fee waiver is NOT made by either your TA or the stockroom window staff. No waivers will be granted after the 1 week grace period. Grading: CHE108-3 -

Estimated cut-offs for letter grades are: 85% = A; 50% = D; even grade intervals in between. Grade cut-offs may be lowered at the discretion of the instructor. Students should keep all examinations, laboratory reports and problem sets until they have received their course grade. These are the only materials which will be accepted as evidence of clerical error in the determination of the course grade. Examinations: Examinations have been scheduled for Friday, 8 March 2019 at 5:00-6:30 PM for Exam 1 and Friday, 19 April 2019 at 5:00-6:30 PM for Exam 2. The final examination is scheduled for Friday, May 17, 2019, at 8:00-11:00 AM. Please clear your calendar for these dates and times! Students should bring their University ID card to all examinations for identification purposes. Make-up Policy: Students who are unavoidably absent from an exam, recitation, or laboratory must present an excuse (obtain form in NSC 361) and should be prepared to document the absence if requested to do so. Laboratories missed because of a valid absence will be prorated on the basis of other work that is done. Make-up exams will be given at 5:00-6:30PM Tuesday, 12 March 2019 for Exam I in NSC. 228 and 5:00-6:30PM Tuesday, 23 April 2019 for Exam II in NSC 228. Incompletes: A grade of incomplete ("I") indicates that additional course work is required to fulfill the requirements of a given course. Students may only be given an I grade if they have a passing average in coursework that has been completed and have well-defined parameters to complete the course requirements that could result in a grade better than the default grade. Prior to the end of the semester, students must initiate the request for an I grade and receive the instructor s approval. Students who present a valid written excuse for failure to take the Final Examination either prior to or within 48 hours of that exam will be given a grade of I (incomplete) if they had a passing average after Exam II. Assignment of an I grade is at the discretion of the instructor. Students with failing averages after Exam II are not eligible for incompletes by University policy, and will automatically be assigned a grade of F if they do not take the Final Examination. I grades must be completed within twelve months; students must not re-register for courses for which they have received an I grade. - 4 -
The instructor must specify a default letter grade at the time the I grade is submitted. A default grade is the letter grade the student will receive if no additional coursework is completed and/or a grade change form is not filed by the instructor. Individual instructors may set shorter time limits for removing an incomplete than the six-month time limit. For spring 2019, the incomplete grade default is Dec. 31, 2019. Upon assigning an I grade, the instructor shall provide the student specification, in writing or by electronic mail, of the requirements to be fulfilled, and shall file a copy with the appropriate departmental office. The Incomplete policy is not retroactive and does not apply to transfer credit. The "I" must be changed to a grade before the degree conferral date if the student plans to graduate in that semester. A default grade can be "B," "C," "D," or "F." (If a student selected an S/U grading option, it will replace the default letter grade when the grade defaults.) Students requesting an incomplete are hereby reminded that University regulations prohibit a second registration in a course for which they currently have an I-grade and that all I-grades must be removed before graduation. Students who stop attending, as judged by their absence from Exam II and the Final Examination, without officially resigning, will be assigned the grade of FX and their lack of attendance will be reported to the Office of Financial Aid at the end of the semester. Students registered with the Office of Accessibility Resources: The Chemistry Department works closely with the Office of Accessibility Resources to make it possible for anyone wishing to take a Chemistry course to do so. Special arrangements can be made for handicapped students who cannot take examinations in the normal manner and for those who cannot perform laboratory experiments unaided with the normal equipment. All such arrangements must be made well in advance of the event by contacting Mr. Randall E. Borst, Director of Accessibility Resources, 60 Capen Hall and the appropriate lead instructor; Dr. Keister for examinations and Dr. Ventura for laboratory experiments. Academic Integrity: The University community depends upon shared academic standards. Academic dishonesty in any form represents a fundamental impairment of these standards. If, after consultation with the student, an instructor believes the student has committed an act of academic dishonesty, the instructor has the authority to impose sanctions in keeping with this principle. The MINIMUM sanctions to be imposed in Chemistry 108 are as follows: First infraction: The maximum point value for the assignment will be subtracted from the student's point total. A subsequent infraction will result in a minimum penalty of 100 points. Students should consult the Academic Regulations and Procedures section of the Undergraduate Education Bulletin for a more detailed discussion of possible harsher sanctions and the appeals process. Academic dishonesty includes, but is not limited to, the following: 1. The possession of crib sheets or unauthorized notes at an examination, whether or not they are used; the display or answering of any electronic device such as cell phone, ipod, mp3 player, PDA, etc. (Calculator memory banks, calculator cases or other articles are subject to inspection by the proctors.) 2. Copying from another person s examination paper or lab report or deliberately allowing another person to copy from you. 3. Changing any of the answers on an examination paper or lab report and then requesting that the paper be regraded for additional credit. 4. Reporting of laboratory work not actually done in the laboratory or using data inconsistent with the numbers listed on the data sheet. - 5 -
5. Copying or altering the copyrighted laboratory computer disks to obtain data without doing the computer experiments as designed. Miscellaneous: NSC 361 (the Copy Center ) will serve as a general office during certain (posted) hours for the following purposes: 1. Extra copies of announcement sheets will be available there and on UBLEARNS CHE 108 Web site under Course Documents. 2. Requests for excused absences may be obtained there. These requests must be signed by the appropriate instructor (lecturer for hour exams and lab instructor for lab experiments) and returned to NSC 361 by the student within seven days of the absence or the date of lab check-out (whichever comes first). 3. Lab reports which students wish to have regraded must be turned in there within one week after the paper has been returned to the student. The nature of the problem must be specified on an attached sheet. Papers containing white-out corrections will not be regraded. 4. Late lab reports must be turned in there. See Lab Notes Sheets for due dates of lab reports. 5. Students will be given a dated and initialed receipt for all materials turned in at the Copy Center. 6. A directory for all Chemistry 108 instructors (with office hours listed) will be posted outside NSC 266, 361 and on the UBLEARNS CHE 108 Web site. Problem Assignments: Problem assignments will be announced in class and also will be posted on the UBLEARNS Web site. UBLEARNS CHE 108 Web site Announcements: Up to date course information and assignments are available through the UBLEARNS CHE 108 Web site. The URL is: http://ublearns.buffalo.edu.
