6 Lab Instructor (TA): Instructor Contact Info.: Office Hours (day, time, & location): Lab Meeting Time and Section Number: Lab Meeting Room: 2027 Malott Hall Chemistry 125 Laboratory - Spring 2013 Course Web site: Lab Director: Roderick Black, 2021 Malott, rsblack@ku.edu Safety: Find the safety regulations for laboratory courses on the following Web site: Review these regulations often. Chemistry Department-approved full-coverage goggles must be worn at all times. If a student is found not wearing goggles at any time while laboratory work is being conducted anywhere in the room, this student will receive a warning or a grade penalty, and may be asked to leave the room. Laboratory students must wear long pants. It is not acceptable to wear shorts of any kind, Capri pants or intermediate-length pants of any kind, or skirts. Shoes must cover the entire foot. Open-toed shoes, open-heeled shoes, sandals, or shoes containing holes are not acceptable. (If a student's attire fails to meet these guidelines because of religious or cultural requirements, the student must contact the instructor in advance of the lab period.) Attendance (5 points each week): You are expected to attend every lab session. There are no makeup labs. All unexcused absences will receive a grade of zero; only a documented physician s excuse, documented school-sponsored event, or documented death of a friend or family member are acceptable excuses. (Alternatively, if you miss lab due to an illness, you may send an note to Dr. Black at rsblack@ku.edu to explain the reason for your absence.) It is not possible to receive a passing grade in Chemistry 125 if you are absent from more than four lab periods, regardless of whether your absences are labeled excused or unexcused. Attendance will be taken at the beginning of each lab period. If you arrive after the lab has begun you will receive an attendance grade of zero. In lieu of attendance points, a 5-point quiz may be administered. To pass a quiz, you must read and understand the lab investigation scheduled for that lab period. The quiz may include questions pertaining to previous lectures and lab experiments. If you arrive late you will not be allowed to take the quiz. Students who arrive late might not be permitted to perform the lab experiment, resulting in a grade of zero for the laboratory manual pages. Lab Manual Pages or Report (25 points each week): Each person must bring to lab their own copy of the Laboratory Manual to Accompany Chemistry in Context: Applying Chemistry to Society, 7 th ed. (2012). You will complete the data sheets and answer the questions in your lab manual, according to the instructions from your TA. At the end of the lab period, the pages containing your data and answers should be removed carefully from the lab manual and given to your TA to be graded. Grading: The laboratory component of this course accounts for a portion of your final letter grade in Chemistry 125. Academic Honesty: There will be repercussions for any form of dishonesty. Plagiarism of a lab assignment, including any portion of the lab manual pages submitted to your TA, is not acceptable. Supplying any part of an assignment via online or offline databases (or via other repositories to which current or future Chemistry 184 students may have access) will be considered academic misconduct. Assignments submitted to your TA must be composed in Standard English using your own words. Assignments may not be copied from published or online sources of any sort, nor may they be copied from the work of any current or former student.
