| The
lab sessions for section 101 are on Fridays from 2:40 PM - 5:40 PM
in
McGowan South 305. The lab sessions for section 701 are on Thursdays from 6:00 PM - 9:00 PM in McGowan South 305. Welcome to the CHE 129 Basic Chemical Concepts Laboratory course! This laboratory course provides hands-on experience with material presented in the lecture component of the course. Lab course topics include volume, density, Avogadro's number, Lewis dot structures, and stoichiometry. ANNOUNCEMENTS: TA OFFICE HOUR Our TA for section 101 is Karla Arias (resevl4eva@hotmail.com). Karla can be available on Mondays (O'Connell 400) and Wednesdays (McGowan South 307) 11:30 am - 1:30 pm for addition help outside of class starting Monday, September 12th. Our TA for section 701 is Jason Kositarut (jkosi@mac.com). Jason can be available on Mondays 1:30 pm - 2:30 pm in O'Connell 400 for addition help outside of class starting Monday, September 19th. Please visit me, too! If you cannot make my scheduled office hours, then please email me so that we can arrange another meeting time. ONLINE SAFETY TRAINING The Safety Office has developed an online-version of the Lab Safety Training for students. If you are in section 101, then you must complete this training by 2:00 PM on September 16th in order to be allowed to conduct the experiments for the course. If you are in section 701, then you must complete this training by 5:00 PM on September 15th in order to be allowed to conduct the experiments for the course. Please click HERE to access the online training. You will need to use your Campus Connection ID and password to log in. During the first week of lab, you must submit a print-out that documents your passing grade for the safety training. ACADEMIC INTEGRITY Academic dishonesty will not be tolerated. All work on which you wish to be graded should be your own. University policies on academic integrity will be strictly adhered to. Consult the DePaul University Student Handbook (http://sr.depaul.edu/catalog/catalogfiles/Current/Undergraduate%20Student%20Handbook/ch1.html) or the Academic Integrity Policy (http://academicintegrity.depaul.edu/AcademicIntegrityPolicy.pdf) for further details. It is acceptable for you to paraphrase information from a source, however, several of you are doing so incorrectly. Paraphrasing is not copying a sentence and changing a word or two; this is plagiarism. In general, when you paraphrase you should read a paragraph, close your book, then write what you just read in your own words. It would be better for you to not write a section of your report and have points deducted than for you to paraphrase or cite a reference incorrectly and get reported to the Office of Academic Integrity. LABORATORY ETIQUETTE You must come to each lab prepared to conduct your experiments. This includes having your pre-lab assignment for the day written in your lab notebook. Before the lab starts, your lab instructor or TA will check that you have the required information in your lab notebook (see the lab syllabus and guidelines); you will not be allowed to enter the lab without it. You may not be given time beyond the scheduled lab period to complete your experiment because you did not come prepared. You are a safety hazard to yourself and to others in the lab if you mix the wrong reagents for your experiment. You must pay attention to the whole names of the chemicals that you plan to use for each step of your experiment, and you should use only the amounts of reagents required. A small excess of reagents will be provided to each lab section; when these amounts have been used up, more will not be provided. At the end of each lab period, you are required to clean thoroughly your glassware and bench space. You must never place dirty glassware in the oven; to do so is a safety hazard because the next person to open the door to the hot oven will inhale vapors of the chemicals left on the glassware. If you have a difficult time cleaning your glassware, please ask your lab instructor or TA for assistance. BUILDING EVACUATION PLAN Although we rarely need to evacuate McGowan South, an accident may occur that would require us to do so. If your lab section must evacuate the building during your laboratory period, please use the east stairs (on the left side of the main elevators) to exit the building. Our meeting location will be in front of the parking lot, which is across Belden Avenue from the McGowan South building. Please go to this specific location so that your laboratory instructor and TA will know that you made it out of the building safely. LAB GUIDELINES The lab guidelines can be downloaded by clicking on the link above. You are expected to have read the guidelines before your first lab experiment starts. For general guidelines to writing a well-written laboratory report, click HERE. Some other pointers for writing your report are below. 1) Avoid including people (students, I, we) in your report. 2) Write the Purpose section in present tense. This section will be called the Introduction in upper-level courses. Present tense is often used because this section contains statements of fact (background and general knowledge). 3) Pretend that you are writing the report for someone who has not conducted the experiment - do not write it for me. When I read your report, I want to see that you understand the experiment. ABSENCE FROM LAB Attendance in lab is mandatory. The lab period will begin and end promptly. You will need to budget your time carefully to complete experiments successfully in the time allotted. |
