Assessment

Students are always expected to act professionally and ethically. All assessments, except where specifically designated as group work, are expected to be the work of the individual using their own, independent research, reflection, learning and understanding of the topic. Group work should reflect the research, reflection, learning and understanding of the group. Use of any online homework sites to answer assessment questions or any other form of academic misconduct will not be tolerated. The internet will be routinely searched for questions used in assessments. Anyone suspected of academic misconduct will be reported to the Chair of Chemistry and Dean of CEPS. An investigation will then follow.

Students must pass the lecture and laboratory parts of the course independently to obtain credit for the course. To pass the lecture portion, an overall grade of 50% must be achieved on the lecture parts of the grades, and a grade of 50% must be achieved on at least one of the two individual exams. Otherwise, a mark of 47% or the mark calculated from the above distribution, whichever is lower, will be the reported grade.

Online Homework

The coursework in Chem 2400/2480 involves extension use of problem-solving skills. Development of these skills and understanding of the material is facilitated by the use of interactive homework assignments. You can choose to complete the online assignments, accessed through the Achieve platform (achieve.macmillanlearning.com) worth 10% of your final grade, as indicated in the previous table.

If you choose not to complete the online assignments, 5% will be added to each of your midterm and final for total exam grades of 19% and 25% for Chem 2400; 23% and 31% for Chem 2480. If an assignment is not attempted, a grade of zero will be assigned. Details on how to register with Achieve can be found on Courselink.

Exams

Both the midterm and final exam will be in-person. The mid-term exam will be 80 minutes, covering the topics listed here in Weeks 1 to 6 (including acid-base titrations). The final exam will be 110 minutes. If circumstances prevent in-person exams, they will switch to an online exam.

 

Course Content

Each unit is approximately two weeks in duration

 

Laboratories

General Information

Chem 2400: Labs are conducted in SSC 3103 and consist of two three-hour labs per week. Chem 2480: Labs are conducted in SSC 3104 and 3103 and consist of one three-hour lab per week.

Labs start the week of September 11th. A detailed lab schedule is provided below. Expect to be in lab for the entire three hours for your first and all subsequent lab periods. Lab manuals will be available for debit or credit sale in the chemistry department during the first week of labs. Check Courselink for details. Students should bring appropriate PPE with them (lab coat, goggles, closed shoes) and a bound laboratory notebook to their first experimental lab. The lab co-ordinator uses a separate Courselink site for grades, quizzes, lab report dropboxes, and for a lab discussion group. Any changes to the lab or the lab schedule will be posted on the lab Courselink site. For more information, see the lab manual.

Lab Schedule

Attendance at all lab periods is mandatory. In case of emergency (family issue or trying to get to the lab is too dangerous) or debilitating infectious illness, you must contact the lab coordinator and the TA to let them know you will not be attending lab (in advance of the lab period if possible). Accommodations will be made by the lab coordinator for the missed lab. Students missing a lab period or lab submission without discussing it with the coordinator will not earn credit for the lab component of the course (they will be assigned a lab grade of zero). Students who miss more than 2 lab periods and/or 2 lab submissions regardless of discussing it with the coordinator, cannot pass the lab, and will be assigned a final lab grade of either the calculated grade or 47%, whichever is less.

Notebook and ULab deadlines

For the first and second grading of the laboratory notebooks, books must be submitted at the end of your lab period(s) for the week. Check the lab manual for details on what must be included in the notebook for any experiment you've started. The schedule below indicates due dates for notebooks and the number of unknowns that must be completed in your notebook for each assesssment. These do not not need to be submitted to ULab at that time. Students are encouraged to submit the result of a particular unknown to ULab as soon as the experiment is completed. In the event of a poor mark, early feedback will allow you to check your calculations and plan you lab work accordingly. At the end of the semester, the results of all remaining unknowns must be submitted to ULab and the lab notebook must be submitted to your TA no later than one day after your last scheduled experimental lab. details. Late notebooks get a grade of zero. See your lab manual for more details.

Learning Outcomes

By the end of this lab, you should be able to:

1. Carry out volumetric, gravimetric, optical and electrochemical experiments in a safe, accurate and precise manner.
2. Create and maintain a lab notebook.
3. Apply time management and organizational skills to independently complete experiments in a timely manner.

E-mail Communication

As per university regulations, all students are required to check their <uoguelph.ca> e-mail account regularly: e-mail is the official route of communication between the University and its students.

When You Cannot Meet a Course Requirement

When you find yourself unable to meet an in-course requirement because of illness or compassionate reasons, please advise the course instructor (or designated person, such as a teaching assistant) in writing, with your name, id#, and e-mail contact. See the undergraduate calendar for information on regulations and procedures for Academic Consideration.

Illness

Medical notes will not normally be required for singular instances of academic consideration, although students may be required to provide supporting documentation for multiple missed assessments or when involving a large part of a course (e.g. final exam or major assignment).

Drop Date

Courses that are one semester long must be dropped by the end of the last day of classes; two-semester courses must be dropped by the last day of classes in the second semester. The regulations and procedures for Dropping Courses are available in the Undergraduate Calendar.

Copies of out-of-class assignments

Keep paper and/or other reliable back-up copies of all out-of-class assignments: you may be asked to resubmit work at any time.

Accessibility

The University promotes the full participation of students who experience disabilities in their academic programs. To that end, the provision of academic accommodation is a shared responsibility between the University and the student.

When accommodations are needed, the student is required to first register with Student Accessibility Services (SAS). Documentation to substantiate the existence of a disability is required, however, interim accommodations may be possible while that process is underway.

Accommodations are available for both permanent and temporary disabilities. It should be noted that common illnesses such as a cold or the flu do not constitute a disability.

Use of the SAS Exam Centre requires students to book their exams at least 7 days in advance, and not later than the 40th Class Day.

Academic Misconduct

The University of Guelph is committed to upholding the highest standards of academic integrity and it is the responsibility of all members of the University community – faculty, staff, and students – to be aware of what constitutes academic misconduct and to do as much as possible to prevent academic offences from occurring. University of Guelph students have the responsibility of abiding by the University's policy on academic misconduct regardless of their location of study; faculty, staff and students have the responsibility of supporting an environment that discourages misconduct. Students need to remain aware that instructors have access to and the right to use electronic and other means of detection.

Please note: Whether or not a student intended to commit academic misconduct is not relevant for a finding of guilt. Hurried or careless submission of assignments does not excuse students from responsibility for verifying the academic integrity of their work before submitting it. Students who are in any doubt as to whether an action on their part could be construed as an academic offence should consult with a faculty member or faculty advisor.

The Academic Misconduct Policy is detailed in the Undergraduate Calendar.

Recording of Materials

Presentations which are made in relation to course work—including lectures—cannot be recorded or copied without the permission of the presenter, whether the instructor, a classmate or guest lecturer. Material recorded with permission is restricted to use for that course unless further permission is granted.
By enrolling in a course, unless explicitly stated and brought forward to their instructor, it is assumed that students agree to the possibility of being recorded during lecture, seminar or other “live” course activities, whether delivery is in-class or online/remote. If a student prefers not to be distinguishable during a recording, they may:

1. turn off their camera
2. mute their microphone
3. edit their name (e.g., initials only) upon entry to each session
4. use the chat function to pose questions.

Students who express to their instructor that they, or a reference to their name or person, do not wish to be recorded may discuss possible alternatives or accommodations with their instructor.
