Be able to use simple instrumentations and calculations required for a general chemistry students effectively and be able to relate theory to experimentation in the laboratory. Grading criteria: (Total = 1000 points) 1. Six exams x 80 = 480 points 2. Labs & Lab Final = 220 points & 100 points = 320 points 3. Final exam = 200 points A = 880 1000 pts, B = 770 879 pts, C = 680 769 pts, D = 550 679 pts, F = 0 549 pts An "A" grade signifies exceptional work accomplished, a "B" grade, superior work, and a "C" grade, average. Doing correctly the minimum work required, earns an average grade ("C"). To earn a higher score, your work must show, in some way, above average effort, understanding, and accomplishment. Attendance policy: Students are expected to attend every class meeting, to arrive on time and stay throughout the class period. Students may be dropped from class for excessive absences or tardiness, for failure to attend class the first day or during the entire first week of the class, or if the total number of absences exceeds twice the number of hours the class meets per week. 2
Academic dishonesty policy: Violations of academic integrity of any type by a student provide grounds for disciplinary action by the instructor or college. Violations of academic integrity include, but are not limited to, the following actions: cheating on an exam, plagiarism, working together on an assignment, paper or project when the instructor has specifically stated students should not do so, submitting the same term paper to more than one instructor, or allowing another individual to assume one s identity for the purpose of enhancing one s grade. For more information on the Standards of Student Conduct refer to the college catalog available in hardcopy and online at www.lattc.edu Disability Support Services (DSS): Students with disabilities who need any assistance or accommodations should contact the instructor and the Disabled Student Programs & Services (DSPS) center located in MA-100 or call (213)763-3773. No Exams will be dropped. No make up exams and quizzes will be given. Assignments MUST be turned in by due date NO MAKE UP LABS WILL BE GIVEN. If you are on schedule to do your lab on Tuesday you must be present on that day; you may NOT make it up on Thursday since others need the stations. Disclaimer: This syllabus and course schedule are subject to change at my discretion. 3
Other information: 1. Classroom decorum policy: no eating, no cell phones, no video games, no texting, no visitors. 2. Instructor will not drop you for poor performance; students have the responsibility to withdraw before the deadline 3. No sitting on the lab bench, eating or drinking during the lab period. Using your personal electronic devices (cellphone, ipod,.) is not permitted. 4. Students must have lab coats and safety goggles when in the laboratory. Open toe shoes (e.g. flip flaps, sandles, etc), tank tops and shorts are not allowed in the laboratory; student(s) who do not adhere to this policy will be asked to leave the lab and will receive a grade of zero. You must have the following lab notebook, no other notebooks will be accepted. The below note book example has a white and yellow copy. I will collect the white copy and you are to keep the yellow. YOU ARE NOT TO USE PENCILS. YOUR EXPERIMENTS/DATACOLLECTIONS/OBSERVATIONS ETC ARE RECORDED IN BLUE or BLACK PEN ONLY. Important Note: Time line for exams: There is a class right after ours. I will give 12-14 questions on each exam and you are expected to finish within 60 minutes. There will be no argument regarding the number of exam questions and the time allocated for each exam. You are college students and are expected to behave accordingly. Make up exams will only be given if you have doctor s note, GOING ON A TRIP OR TO A WEDDING IS NOT A VALID EXCUSE!!!!!! 4
