CHEMISTRY DEPARTMENT

Chemistry C083/H093 (Laboratory) [and Chemistry C081/H091 (Lecture) and C081R/H091R (Recitation)] is offered only in the Fall term. This course serves as the first semester of General Chemistry Laboratory for Chemisty Majors (C) and Honors (H) students. It is understood that, at least high school algebra and chemistry have been successfully completed by class participants. Thus, it is presumed that students will participate by completing the reading assignments prior to coming to class and that they are comfortable with some laboratory equipment and techniques. Hopefully, the laboratory time can be used to build on this prior knowledge

Attendance:Attendance in lab is mandatory. Your grade will be based on the labs you complete in class, in addition to other items. Therefore, if you are not present to perform the lab your grade will obviously suffer. The class begins promptly at the scheduled time. You are expected to arrive to class on time and prepared. Any student arriving more than 15 minutes late to class will not be admitted. Those students who arrive to class chronically late will have their grade lowered. If you will be absent for a legitimate reason you should inform your lab instructor immediately and follow the appropriate make-up procedures.

Make-ups: If you can provide a valid excuse for missing your regular laboratory class, you may be permitted to make-up the missed class, at another class time DURING THE "WEEK" IN WHICH THE EXPERIMENT IS RUNNING. Chemicals and equipment in the teaching labs are changed on a weekly basis; therefore if you delay you will find the items you need are no longer available. This may mean you need to make plans in advance of your absence. No more than TWO (2) lab classes may be completed this way. There are no make-ups during the laboratory midterm and final exam weeks. To make-up a lab you should get a Lab Make-up Request Form from the service window.

C081/H091 is a corequisite of C083/H093, therefore only those students who are enrolled in (or have successfully completed) C081/H091 or its equivalent should be taking the lab class. It is expected you will read the laboratory materials and complete the pre-laboratory assignments BEFORE you attempt to carry out the experiment.

Lab Safety: Laboratory safety is a major concern and therefore it is required that all students purchase, read, understand and sign the Temple University Student and Laboratory Use General Guidelines for CST (available in the Temple University Bookstore or at the University Copy Center -601 Conwell Hall). Students will not be permitted to continue working in the labs after the second week of classes without this signed document

It is expected that everyone in the lab conduct themselves in a professional manner. If you are unable to comply with the safety rules please withdraw from the course. While you are working in the lab you will wear a pair safety glasses. There are no exceptions. Students who will not comply are not permitted in the laboratory. In addition you should wear appropriate clothing and shoes. No shorts, mini-skirts, sandals, or open toe shoes. Anyone who wears contact lenses should inform their instructor; we strongly suggest you not wear them in the lab! Any student who is pregnant or may become pregnant during the course of the semester should consult a physician to decide whether or not it is advisable to continue in the course. In addition, any students with any medical conditions that might require special treatment in the event of injury should inform their instructor, so that in the event of an emergency we may respond appropriately.

In the event of a minor emergency the student will be escorted to Mitten Hall, Student Health Services. If the student requires Hospital treatment, the campus police (1-1234) will be contacted. It is important you know the location of safety shower(s) and eye wash(es) as well as doors and windows and hoods. You should be able to find the eye wash fountain nearest to your work area with your eyes closed.

Preparation: When you arrive to lab class you should have read and outlined the experiment. This may look like a lot of work but it will save you a great deal of time and aggravation in the laboratory. Many of the procedures in the experiment are complex. It is very easy to make a mistake, which may require you to repeat the entire experiment. So the extra 20 minutes outside of class can save you hours in class. Every student should have a hand-written outline of the day's experiment in ink. No photocopies, printouts, carbon copies! This outline should be detailed enough that you or anyone else familiar with the experiment could easily follow the procedural steps to complete the lab. During the lab your instructor will come around to check your outlines which will contribute to your lab report score. Students who, in the opinion of the instructor, are unprepared for the class may be ejected from the lab since they pose a danger to not only themselves but also their classmates.

Clean-up: Every student is responsible to help keep the laboratory clean and safe! If you encounter a spill, how do you know what that chemical is? Is it dangerous? This means individual students MUST clean up their own chemical spills. If the spill is large or if the chemical used is dangerous, inform the instructor immediately. This also means that students need to make sure the reagent bottles (solids and liquids) are re-capped securely and returned to their proper location. If you find a reagent bottle out of place or uncapped, even if you did not do it, take the time to re-cap and return the bottle. All students should be extra attentive when using chemicals in the hoods or balance rooms. To help assure the lab is left clean and safe, two students will be assigned to "clean up detail" each week. These students will be responsible for staying to the end of the lab (even if they finish early) and cleaning-up any spills, returning reagent bottles, cleaning up any leftover glassware, etc. Failure to perform these duties or doing an unsatisfactory job will result in a reduced score. If you see other students failing to clean up after themselves or leaving reagent bottles open, politely remind them. If everyone does his or her job the "clean-up detail" will have little or no work to worry about.

Grading: For those students who hand in their lab reports on time, every effort will be made to return them the following week. Those students who handed in material late will get their reports returned at the convenience of the instructor. If you want your report back to study from, make every effort to hand it in on time. You should keep and record of all of your lab and exam scores in case there is a discrepancy later in the semester. Without a copy of the graded lab report the instructor will have to rely on the grade book and/or memory. A complete breakdown of points is provided below. Note that the final exam is cumulative. Your instructor may use the instructor evaluation portion of the lab score to access several items including: your conduct in the lab, compliance with safety rules, tardiness, participation, clean-up, etc. Although this is a one-credit course a great deal is expected of you. This is considered when letter grade assignments are made. However, it should be noted that an 'A' is a difficult grade to attain.

Material Due: Every week (for each experiment) you are expected to prepare a pre-lab exercise as well as hand in the completed lab report for the previous experiment. This material will be collected before the pre-lab discussion, so come to class prepared. You will NOT have time during class to complete this work. Material received after the pre-lab discussion will be considerd late (-5 points). This also applies if you arrive to class late. You will lose 10 points/day late on all lab reports. It is the students' responsibility to keep a record of all their assignments and scores. Do not wait until the "last minute" to work on a lab write-up and seek help outside of class if you have difficulties.

Late Material: Late material should be handed directly to your instructor. If you choose to leave the material under their office door, in their mailbox (in BE 201), or with someone else, your instructor can not be held responsible for your report becoming lost. (You should consider making a copy before handing it in.) If you use the Chemistry Department mailboxes (BE 201) be certain you are placing your work in your instructor's mailbox. If you don't know your instructor's name, check before using the mailboxes.

Lab Partners:All students are expected to perform the experiments individually. In some instances students will be required to work in pairs (not groups of three or four!). During those experiments the work should be a joint effort on the part of both students. Specifically if the experiment requires two more trials, each student should complete at least one trial while the other student assists. As lab partners you may have identical experimental data and discuss the lab report with your lab partner (or others) but your lab reports should be your own interpretation of the experiment and should therefore be sufficiently different from that of any one else.

Problems:You should first attempt to resolve any problems that you are having with your Laboratory (or Recitation) instructor(s). If after speaking with the instructor you have not resolved the issue you should speak with the Dr. Dalton. He will attempt to mediate, but the ultimate decision regarding grading, make-ups, etc. are left to the instructor. However, if you are having problems with the professional conduct of your instructor you should contact Dr. Dalton immediately.

Withdrawal: Please note that a withdrawal is an institutional procedure which is not complete until the withdrawal form has been signed and submitted to the Registrar's office. Students may withdraw from C081/H091 and C083/H093 without a grade of W at any time up to and including Fri. 18 Oct. After this date those who withdraw will be assigned a grade of W or WF, depending upon their midterm scores. Those withdrawing from C083/H093 must obtain a note from the service room clerk stating that they have checked out of the lab. You may not continue in C083/H093 if you withdraw from C081/H091. NO WITHDRAWALS WILL BE PERMITTED AFTER Mon. 18 Nov . All withdrawal slips (for C081/H091 and C083/H093) must be signed by Dr. Dalton, NOT your Laboratory or Recitation instructors.
