Required Items: The Official Laboratory Research Notebook, safety glasses, laboratory coat (all are available at the SOU Bookstore)and a USB flashdrive on which to save lab data.
"A Short Guide to Writing About Chemistry" Davis, Tyson, and Pechenik, 1st Ed., Pearson 2010 (ISBN 0-205-55060-6)
Corequisites: Ch 205 must be taken concurrently with Ch 202. Please note that a passing grade (C- or better) in Ch 204 is required for students moving to Ch 205 in the Winter term.
Final Exam: Experiment 18: Ten Tubes (done during the last week of classes, not during finals week.)
Grades: Grades will be based on the total points earned in the course. Each lab report is worth 50 points, and the final exam is worth 75 points. The grading scheme is flexible, but approximate grade cutoffs will be 90% of the points for A's, 80% for B's, 70% for C's, and 60% for D's.
Guidelines: Each class will meet initially in a classroom for a prelab lecture for 30-50 minutes. This time will be used for clarifications of the procedure, including how to handle the data and write up the report. Students are responsible for reading the experiment and entering specific information in their lab notebooks before coming to class. Attendance at this session is mandatory to receive a grade for the experiment. You will not be allowed to conduct the experiment if you miss the prelab session or the required information has not been entered in your notebook. This leadoff session will be followed by 3 hours of work in the laboratory. All work must be completed by the end of this three hours - no extra time will be allowed. Poorly prepared students will have trouble completing the assignment in the scheduled time.
Lab Safety: Safety glasses and lab coats are required at all times in the laboratory. These items may be purchased at the bookstore and should be kept in your drawer in the lab. Long pants are required in lab, and no open-toed or opened-backed shoes (e.g. sandals, flip flops, etc.) are permitted in the lab - you will be sent home to get proper footwear and clothing if you show up to lab in shorts and sandals. No food or drink is permitted in the laboratory - no exceptions. Backpacks, coats, etc. must be hung on the racks provided at the rear of the lab and not left where they may block the aisles. Other considerations with regards to lab safety will be addressed by your instructor during the first week and during weekly lab meetings. Please note that repeated safety violations will result in your being asked to leave the lab (therefore you'll receive a grade of zero on that particular report). Repeated serious safety violations may result in your being dropped from the course.
Laboratory Notebook: All observations should be entered directly into the Official Laboratory Notebook in ink. If you make an error, draw a line through the entry, and write it again; don't try to erase, or try to write over the original entry. Include a table of contents in the front. The introduction, lab procedure, and an outline of data to be collected must be entered before you come to lab each week, and the duplicate page from your notebook will be collected at the beginning of the lab period. A portion of each lab report grade will be based upon the quality of your notebook pages (i.e., the prelab and your data and calculations.)
Lab Reports: You will be given explicit instructions on expectations for each lab report. The most common causes of poor scores are failure to turn in reports on time, and failure to follow the required format. Guidelines for format and content are contained in the General Chemistry Lab Manual on page 11, and examples of good and bad reports are given on pages 15 and 19, respectively. The text by Davis, et al. is an excellent resource for help on lab reports.
Ch 205 Lab reports will be graded according to the rubric linked here. Each section of your lab report (Intro/Method/Results/Discussion), in addition to mechanics and formatting, will be worth a maximum of 5 points. Please print the grading rubric and bring it with you to prelab. Grading for each lab (i.e., weighting of each section in the lab report) will be discussed in prelab each week.
All reports must be word processed and all graphs must be computer generated. Reports are due at the beginning of the next lab period. Late reports may receive a maximum grade of 80% (up to one week late). Reports will not be accepted more than one week late. You are urged to begin work on your lab report as soon as possible after your lab section has met and you've collected your lab data. You have a week to produce a report so there is absolutely no reason to wait until 30 minutes before your lab section next meets to finish your work!
Feel free to work with and consult with your classmates in making calculations, plots, etc., but plagiarism is unacceptable. According to the SOU Student Handbook under Academic Standards: "Plagiarism is defined as knowingly submitting the language, ideas, thoughts, or work of another author as one's original work, or allowing work to be used in this fashion." In the case of two students submitting identical or very slightly altered but essentially identical lab reports, both students will receive grades of zero for that particular report. Disputes on this point will be referred to the Dean of Students' Office, and copies of the disputed lab reports will be forwarded to the Dean of Students for review.
Attendance: Please contact the instructor if illness
prevents you from attending your lab session. You are not allowed to
attend a different lab section without the written permission of both
your own lab instructor and the instructor of the other section.
Permission is not automatic, and depends upon the reason for your
request, and the number of available spaces in the other lab section.
Permission is obtained by printing out the form found at this link, and
bringing it to the two instructors for signatures. The instructor
reserves the right to determine what constitutes an emergency.
Check-out: You must check out of your lab drawer and return your key to the Chemistry storeroom by the end of the term if you drop the course, or during the normal checkout time at the end of the term. If you do not check out of your lab drawer and return your key to the storeroom by the last day of finals week, you will be assessed a $50 fee to cover the cost of cleaning the drawer and re-keying the lock.
Policy on Academic Dishonesty
Because originality of thought and integrity of scientific data are central to the scientific enterprise, the SOU Chemistry Department has a zero-tolerance policy towards academic dishonesty in any form. Acts of academic dishonesty include but are not limited to: plagiarism, deliberate falsification of scientific data, submitting or enabling the submission of identical lab reports or portions thereof, bringing unauthorized materials to examinations, looking at another student's work during an exam, or otherwise obtaining grades under false pretenses. Academic dishonesty will be addressed in accordance with the Academic Standards policy at SOU (http://arcweb.sos.state.or.us/rules/OARS_500/OAR_573/573_095.html). All cases of academic dishonesty will be forwarded to the office of the Dean of Students for further review. The institution reserves the right to impose further sanctions in accordance with the SOU Student Code of Conduct (http://arcweb.sos.state.or.us/rules/OARS_500/OAR_573/573_075.html). Such sanctions may include suspension or expulsion from the institution depending on the severity and frequency of the offense.
