2 ABOUT THE COURSE Lecture: Students must be registered for lecture and should attend all lectures. They should read the text in advance for a better understanding of the lecture and are responsible for learning the material presented whether they attend or not. Recitation: Students must be registered for recitation and laboratory (a four hour contiguous time period) as well as for lecture. The recitation period involves discussion of lecture material and homework assignments. Three 15- minute quizzes will be given in recitation during the semester (see schedule) which cover recent lecture material and problem assignments. Problem assignments are made weekly (see schedule). CHE107 recitations meet only on alternate weeks during the semester for quizzes and discussion of problem sets. Homework: Homework will be due on-line through Mastering Chemistry. An access code is required for new students. Books purchased at the bookstore are packaged with an access code that allows you to register. You may also purchase an access code online. Go to the website: and click the Students button. Indicate whether you have an access code and select continue. Then enter the requested information, including your access code, to register to Mastering Chemistry. Please be sure to accurately enter your UB person number so that you receive credit for your assignments. This is the eight digit number that appears on your student ID card. Once you are logged in, enter the University at Buffalo General Chemistry CHE 107 course with our class ID. The Class ID is UBCHE107S2018. See video on UBLearns under Course Documents for any problems with Mastering Chemistry registration or questions can be directed to the help chat on the website, or the help number Laboratory: Student Class Schedule cards DO NOT indicate the correct room for the CHE 107 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. CHE107 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, safety monogoggles, long sleeve shirts, long pants and shoes with closed uppers be worn for all lab work including lab check in and checkout. Shorts, halters, midriff tops, roller blades, electronics, and headsets/earbuds are not permitted. Students will receive one warning for failure to observe the safety goggle requirement. Failure to comply immediately or a second violation will result in expulsion from the laboratory and a grade of 0 (zero) for that day's laboratory work. Students are expected to read the experiment of the day, write up a flowchart, and complete the assigned prelaboratory questions before recitation and pre-laboratory discussion. 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 is due at the next lab meeting and should be turned in at the beginning of recitation. Student I.D. cards must be used to check out certain laboratory equipment at the stockroom. Direct any questions about lab work to the Laboratory Directors, Mrs. Clarke. Laboratory experiments are directly related to the General Education requirement for natural science for understanding the methods scientists use to explore natural phenomena, including observation, hypothesis development, measurement and data collection, experimentation, evaluation of evidence, and employment of mathematical analysis.

3 A laboratory safety awareness test has been scheduled for all recitation/lab sections. The test will be given during the recitation periods held Mon. Feb. 12 Thurs. Feb. 15. Students should read pages (Lab Rules and Regulations, Laboratory Safety and Safety Precautions) in the lab manual, and view the Laboratory Safety and Check video streamed to the UBLearns course website 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 Checkout Charge: All students must check out their lab drawer during their regular lab period (with their lab instructor) during the week of check-out (May 7-10, 2018). Those who do not are subject to a $ check-out charge plus charges for any 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 during their scheduled lab time to avoid the 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 $ fine/penalty waived. This form requires written documentation from a physician verifying the reason for the absence. Grading: CHE107 Recitation Quizzes 15 ) 45 Group work 3) 15 Problem Sets 6) 60 Recitation Total 120 Laboratory Laboratory Reports 10+1) 55 Written Laboratory Final Exam 25 Laboratory Total 80 Examinations Hour Exams (2@ 100) 200 Final Exam 200 Examination Total 400 GRAND TOTAL 600 The final course grade (A-F including +/ 's) is determined strictly on the basis of the total number of points accumulated; individual exams, quizzes, etc., are not assigned letter grades. 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, quizzes, 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: Hour examinations have been scheduled for Friday, March 9, 2018 from 5:00-6:20PM for Exam 1 and Friday, April 13, 2018 from 5:00-6:20 PM for Exam 2, in rooms to be announced. The final exam will be Monday, May 14, 2018 from 11:45AM-2:45PM in rooms to be announced. Please clear your calendar for these times! Students should bring their University ID card to all examinations for identification purposes. Copies of previous year's examinations may be obtained on the UBLearns web-site. Make-up Policy: Students who are unavoidably absent from an exam, recitation, or laboratory must present an excuse (obtain form in NSC 361 or on UBLearns in the Excused Absence folder in Documents) and should be prepared to document the absence if requested to do so. Quizzes or laboratories missed because of a valid absence will be prorated on the basis of other work that is done. Make-up Hour exams will be given at 5:00-6:20PM on Monday, March, , in Nat Sci. 228 for Exam 1 and on Monday, April , at 5:00PM in Nat. Sci. 228 for Exam 2.

4 Final Exam: The CHE 107 final exam is scheduled Monday, May 14, 2018, from 11:45AM-2:45PM in rooms to be announced. Incompletes: 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. Students with failing averages after Exam II are not eligible for incompletes and will be assigned a grade of F if they do not take the Final Examination. The default grade for an incomplete will be computed based on 600 points with the final examination counting 0 points. Incompletes obtained spring 2018 must be removed by examination by Dec. 31, 2018, by taking a make-up exam at the regularly scheduled CHE107 Final time in December 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 F and their lack of attendance will be reported to the Office of Financial Aid at the end of the semester. Limited Enrollment Course: Please be advised that CHE 107 is designated as a limited enrollment course, which means that the enrollment in this course is limited by the number of student positions available. Self-registration in this course in the fall and spring semesters will be limited to those students who are taking the course for the first time. Thus, repeat enrollment may be difficult or impossible in the fall and spring semesters, and students who plan to repeat the course for any reason should plan to register for CHE 101 in the summer to serve for grade replacement. Repeat enrollment is defined as: a student who was previously enrolled in the course at UB, or who transferred an equivalent course to UB, who received a letter grade of A, B, C, D, or F and qualified values thereof (e.g. A-, D+ ); or a grade of P, S, U, I, J, N, or R. The only case in which a student may self-register for a repeated course is when the student has taken an Administrative Withdrawal for an entire previous semester, so that all the grades for that semester were registered as W. Students may petition for enrollment in such a designated spring course by the third week of the preceding fall semester, and in a fall course by the third week of the preceding spring 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. Arrangements can be made for students who do not take examinations or quizzes in the administered time and place, and for those who perform laboratory experiments with alternate accessibility arrangements. Arrangements must be made well in advance by contacting Mr. Randall E. Borst, Director of Accessibility Resources, 60 Capen Hall and the appropriate lead instructor: Dr. Liwosz for examinations and Mrs. Clarke for quizzes and 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 107 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.

5 Academic dishonesty includes, but is not limited to, the following: 1. The possession of crib sheets or unauthorized notes at an examination or quiz, whether or not they are used. (Calculator memory banks, calculator cases or other articles are subject to inspection by the proctors.) 2. Copying from another person s examination paper, quiz, or lab report or deliberately allowing another person to copy from you, including handing in work that is not your own original work. 3. Changing any of the answers on an examination paper, quiz, or lab report and then requesting that the paper be re-graded 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. 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 107 Web site under Documents. 2. Requests for excused absences may be obtained there. These requests must be signed by the appropriate instructor (lecturer for hour exams, recitation instructor for quizzes, 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. Quiz, Lab reports, & Exam papers which students wish to have re-graded must be turned in there within one week after the paper has been received by the student. The nature of the problem must be specified on an attached sheet. Papers containing white-out corrections will not be re-graded. 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 107 instructors (with office hours listed) will be posted outside NSC 266, 361 and on the UBLEARNS CHE 107 Web site. Problem Assignments: Problem assignments will be posted on the Mastering Chemistry homework site.
