Objectives
Because chemistry is an experimental science, you must experience a laboratory setting to understand the subject. In this chemistry lab, you will develop skills in using lab equipment, heighten your powers of observation and measurement, and increase your abilities to interpret and analyze results. Most of the labs will complement our discussions from lecture.
Course Activities
Laboratory: The exercises performed in the lab are designed to give you a feel at a simple level for how chemical experiments are done and to show how an experimental result can support or contradict a hypothesis. Make sure you have read thematerial for the lab to be performed that day and have, where requested, answered the pre-lab questions. For some labs you will be asked to use spreadsheet graphing programs.
Recitation: The recitation will provide an informal setting for questions and discussion of lecture material, of laboratory exercises and of suggested homework problems (see web page). Please come to class prepared to ask questions and get involved in problem solving.
Attendance
Attendance is required for all laboratory experiments. If you have a good reason to miss a lab, you may be allowed to attend the other lab section that day (consult with the lab instructor). Any lab not performed will receive a zero. The lowest lab report grade will be dropped to allow for illness.
Safety
All students are required to wear goggles at all times in the lab. As long as anyone in the lab is doing lab work, you must wear goggles, even if you are done with the lab or are only writing in your notebook. In addition, you must wear long pantsandshoes that completely cover the toe in the laboratory. If you arrive without goggles, long pants or appropriate footwear, you will not be allowed to start the lab until you have corrected the problem. If you live far from campus, you might consider putting an extra pair of appropriate shoes and long pants in your car or backpack. If the clothes you are wearing do not sufficiently cover your torso, you must wear a lab apron or lab coat.
Grading Procedures
The laboratory work will be worth 25% of the total course grade for SCHM 109. There are twelve lab exercises planned for the summer session. You will need to perform each lab and complete a lab report for each one to get credit. Completing a report for all or any portion of an exercise that you did not actually perform would be a violation of the student honor code. Each lab report will be worth ~1 point. Other factors that influence the lab grade are: preparation for lab, punctuality, proper lab technique, and safe lab practice. (Grades on lab reports will be lowered at the discretion of the instructor if you do not clean up after lab or are repeatedly late for lab.) Most of the lab reports will be due two meeting days after it is performed. At the end of the semester, this time may shorten. If a lab report is turned in late, but before the instructor has returned that graded lab to other students, the grade will be reduced by 30%. That is, the maximum credit that can be received for turning in a 1 point lab report late is 0.7 points. However, no credit can be received for a lab report turned in after the instructor has returned that lab to the class.
There will be several quizzes that cover the lab material. See the schedule below for details. There will also be a safety quiz worth one point.
Below are some criteria on which your lab reports will be graded.
1. All parts of the experiment are performed, and they are conducted in a safe manner.
2. All the required data/observations are obtained and recorded in the appropriate location.
3. All questions are answered clearly and accurately.
4. All calculations are performed accurately and presented clearly, with correct significant figures & units.
5. All work is legible.
6. The report is turned in on time.
--AND VERY IMPORTANT!--
7. The data and calculations presented are your own. The answers to questions must be the result of your own thinking and writing. You must perform all calculations. Do not copy or plagiarize. Also, do not let your work be copied. If you need clarification in this area, talk to your instructor and see “The Code of Academic Integrity” in the Student Handbookor at
Grading Summary: Lab reports 1 pt each (12 pts), Library assignment (2 pts),

In keeping with University policy, any student with a disability who requests academic accommodations should contact Disability Services at 503-5199 to arrange a confidential appointment with the Disability Services Coordinator. Students are encouraged to seek an appointment as early in the semester as possible, as accommodations are not provided retroactively. Letters of accommodation must be signed and printed on letterhead from the Disability Services office. It is the student’s responsibility to provide these letters to professors in a timely manner so that accommodations may be put in place.
Consult a physician if you are pregnant or have any other medical condition (asthma is an important example) that might render you susceptible to problems from the chemicals used in laboratory.
Academic Honor Code Issues: The USC Upstate Code of Academic Integrity can be found in the USC Upstate Student Handbook. Please refer to the Handbook if you are unfamiliar with the Code.
Do not copy homework assignments or lab reports from other students and do not let other students borrow your work, as their copying your work could compromise your academic integrity. What many students call “working together” often results in working too closely and copying.
If you have uncertainty at any time about whether a piece of work or particular activity might be a violation of the Student Honor Code, ask! For copying associated with lab reports, students may receive only a warning for the first offence. Depending on the nature of the first offence, credit of that work may be reduced to zero. A second offence will be taken to the Dean of Students and then to Honor Court.
Disclaimer: The instructor reserves the right to adjust the syllabus & schedule as necessary.
