Please turn over Chemistry 101B Lab Fall 2011: Lab MW 2-5 pm, S 243 (Sec 021, CRN 73571) or TR 8-11 am, S 242 (Sec 022, CRN 73572) Required Supplies: Chemistry 101B Laboratory Manual Laboratory Notebook with bound, quadrille-ruled pages Safety glasses with side shields or goggles Scientific calculator Suggested Supplies: Permanent markers (Sharpie or similar) for labeling glassware, ruler Attendance: Required at all laboratories. You cannot pass the course without participating in the laboratory. Students missing more than three consecutive laboratories without notifying me may be dropped from the course (W grade assigned). You must attend the laboratory for which you have registered. You may not attend sessions of the other lab section without permission. Permission will be given only when you must miss your own lab session because of an excused absence (illness or personal/family emergency). Please arrive on time for each laboratory session so that you are present for all of the pre-lab discussion. Students who miss the pre-lab discussion will not be allowed to perform the experiment and will receive a score of zero. Withdrawal: If you decide to withdraw from the course, it is your responsibility to contact the registration center by submitting the proper form in person or by using the WEB4 (web registration) system. I will not drop you automatically for non-attendance. I will assign a failing grade if you stop attending without filing for withdrawal. The deadline for withdrawing from the class is November 17. Late Work: A penalty will be deducted from the score of any late assignments. The penalty is 10% for each lab period after the due date. Work more than one week late will not be accepted or graded. Laboratory Notebooks and Reports Follow the format and guidelines given on the handout Chemistry 101B Laboratory Notebook Policy. The title, purpose and procedure are your pre-lab and must be written before you come to lab. I will check notebooks at the beginning of each experiment. During lab, record all data and observations directly in your notebook—do not use other pieces of paper. Each day, please have your notebook initialed by me before you leave the lab. For selected experiments, I will collect a lab report, which will be a copy (either photocopied or carbon copy) of your notebook.2 Grading: Lab Reports/Notebooks For each graded experiment, your score will be determined by your adherence to the lab report and notebook format, your advance preparation, your compliance with safety measures, and your use of the lab notebook for recording all information. After one warning, I will deduct one point from your lab score every time I see that you are not using your notebook to record all data directly. Most lab reports will be graded by checking them quickly. I will examine each lab to see that all sections of the report are completed in your notebook. Points will be assigned as follows: Prelab 1 (checked and credited the day the experiment starts) Title 1 Purpose 1 Procedure 1 Data and Observations 2 (all data must be complete and clearly labeled) Calculations 2 (a sample of each kind of calculation must be shown and must be clearly labeled and correct—for additional trials of an experiment, you may list the results clearly—a table is useful for organization) Conclusion 2 (this must include a clear summary of the results, indicating how they relate to theoretical expectations, and analysis of a possible experimental error) For some experiments, I will check your results and calculations using a report sheet that I provide. I will grade three or four experiments in depth. These will be based on a fifteen or twenty point scale, with proportionally similar point allotments to the ten-point scheme given above. Quizzes There will be two fifteen-point quizzes covering the lab experiments during the semester. Each of these will be announced. Total Lab Score Reports/Notebooks: 95 points (total of all scores will be normalized to 95 points) Quizzes 30 points Academic Integrity and Honesty: All work you submit must be your own. It is OK to work on your reports with other students, but each student must use his or her own words in writing the various parts of the lab report. If I see identical wording in your reports, I will not give you (or the other person) any points for that particular
