Required Materials |
text: Exton, D.B., General Chemistry in the Laboratory (2008) A scientific calculator (graphing calculator recommended). Bound laboratory notebook with perforated duplicate pages.

Computer Usage |
Laboratory reports for CH 228 must be typewritten or word processed. In addition, computer access may be required for completion of some laboratory assignments. As the campus has several excellent computer labs, it is not necessary that you own a personal computer. However, you should familiarize yourself with the campus computer facilities as soon as possible. |

Course Content |
This is the second course of the three term general chemistry laboratory
sequence. In general, course content will correspond with
material covered in the general chemistry lecture sequence (CH 222). Please note that CH 222 is a course co/prerequisites.
Students will have the opportunity to perform experiments which
illustrate and verify the chemical principals which have been learned.
However, be forewarned that at times the lecture and laboratory courses
will come "unstuck", with one course moving ahead of the other. At other
times, the laboratory may cover material which is important to the
practice of experimental chemistry but which will not be covered at all
in your general chemistry lecture course.
|
| Lab Lecture: |
Mon 15:00 - 15:50 Rm.150 COL There are two components to this course Ð the laboratory lecture and the actual laboratory. The lab lecture will address the relevance and theory behind each of the experiments. Attendance at the laboratory lecture is necessary to ensure that you understand the underlying concepts, calculations and procedures associated with each lab. You are expected to have read over the upcoming lab before attending the lecture. |
|
Laboratory: |
All laboratory sections meet in Rm. B63 Klamath (basement of Klamath Hall). There are eight laboratory exercises scheduled this term. See the winter term laboratory schedule for a complete listing of experiments. |

Laboratry Notebook, Reports, Grades, and Procedures |
Notebook and Pre-lab: Refer to the laboratory text for laboratory notebook and pre-lab guidelines. Unless otherwise instructed, the pre-lab write-up must be written in ink in your notebook before attending lab. If you fail to complete the pre-lab preparation before attending lab you will be considered unsafe and will have to leave the laboratory until the pre-lab is completed. No additional time will be granted to complete the experiment. Your laboratory GTF will check for completion of the pre-lab at the beginning of the lab section. After recording data, observations and results in your notebook, you will turn in carbon copies of your notebook pages before leaving the lab. Lab Reports: Lab reports are due at the beginning of the lab period the week following the experiment. Reports may be submitted up to 7 days late with a 30% penalty. A lab report that is more than 7 days late will be given a grade of zero. Each report is worth 100 points. Reports must be typed or word processed. Guidelines for writing a lab report can be found on the course web page as well as the laboratory text. SafeAssign: In addition to the written lab report, all reports must be electronically submitted to SafeAssign to check for plagiarism. Reports must be uploaded to SafeAssign by the beginning of lab one week after the experiment was performed. If you submit a late lab report, the report must be uploaded to SafeAssign on the same day the report is turned in. Failure to upload your lab report to SafeAssign will result in a score of 0 for that lab. To Upload a Document to Safeassign:
Grading: All disputes involving grading must be discussed with your GTF within two weeks after the question set or lab report has been returned to you. Final grades for this class are assigned on a curve based on each GTF's average. In other words, students with a given GTF will not be graded in comparison with students with a different GTF.
Final point totals will be based on the following:
Laboratory Reports (8) 800 pts
Question Sets 100 pts
------------------------------------
Total score possible 900 pts

| Academic
Dishonesty |
Academic dishonesty in any guise, including plagiarism, fabrication, and cheating, will not be tolerated. All work submitted under your name must be your own and produced exclusively for this course. The use of sources (ideas, quotations, paraphrases) must be properly acknowledged and documented. Because one of the best ways to fully learn a subject is to try and teach it to another person, collaborative and group work are very much encouraged. However, the laboratory report that you submit must be your own work. Copying ANY PART of another student's lab report, reading questions or exam, or allowing another student to copy ANY PART of your lab report, reading questions or exam is cheating. The minimum penalty for plagiarism in this course will be an automatic zero on the assignment. In extreme cases, instances of plagiarism will result in a failing grade in the class.
|
| Make-up Labs |
If a situation arises in which you must miss lab, you may
attend another section that same week to make up the lab if there is space available. Please
note that this requires written authorization. If you need to
attend another section, obtain an authorization form from the
instructor, check in at the stockroom window, and give the authorization
form to the GTF in the lab. Lab reports must still be turned in at the
usual time (i.e. your next lab session). If you are unable to make any
other arrangements, you have the option to do a make-up lab during the
last week of the term. The make up is intended for only those
students who have missed a lab for a legitimate purpose, not those who
attended lab but didn't turn in a lab report or received a poor grade. Make-up labs this term are scheduled for Monday, Mar. 8 at 3:00 pm and Tuesday, Mar. 9 at 11:00 am. Sign up for the make-up lab during the week of Mar. 1. There will be no lab lecture accompanying the make-up lab.
|
| Safety |
Safety in the
laboratory is our #1 priority and safety rules will be strictly enforced. Safety awareness, attitude, and knowledge are all required to ensure a safe environment for yourself and others in the lab. Read the safety section of the lab manual before attending the first lab session. Further safety guidelines will be presented as needed at the beginning of each laboratory experiment. Goggles. Goggles will be provided by the chemistry department. Most violations of laboratory safety involve the improper use of safety goggles. Anytime you are in the laboratory, you must have on your safety goggles. This includes times when you are working on data analysis or cleaning up at the end of the experiment. Your goggles must be covering your eyes. Goggles provide no eye protection when they rest on the top of your head. Tampering with the goggles may result in expulsion from the lab with no extra time granted to complete the experiment. Shoes. Shoes must have fully closed toes and heels. Open-toe shoes, sandals and traditional open-heel clogs are not permitted in the laboratory. Clothing. Clothing ust completely cover the body from the shoulders to the feet. Shorts, short skirts, and camisole tops are not allowed. Students wearing improper attire will not be allowed to remain in the laboratory after the initial discussion period. Any student who receives two warnings in one laboratory period regarding the improper use of safety goggles or other safety procedures will receive a 5 point penalty for each subsequent infraction and may be asked to leave the laboratory. There will be no opportunity to make up the missed laboratory time.

| Students with Disabilities | The University of Oregon is working to create inclusive learning environments. Please notify me if there are aspects of the instruction or design of this course that result in disability related barriers to your participation. You may also wish to contact Disability Services in 164 Oregon Hall.
|
| Inclement Weather Policy |
In the event that a class must be cancelled due to inclement weather, an announcement will be made on the CH 228 Blackboard web site and an email will be sent to all students.
|
| E-mail Policy: | Email is a very handy method for communicating with people, whether around the world or across campus. In some situations email protocol is not as formal as paper communications. In others, (academics, jobs, etc.) there are some expectations of protocol. I ask that when communicating with me (or any faculty member) by email, you adhere to the following guidelines:
