Lab Assignment Policies

Each type of assignment is worth a different number of points as given in the table below and are grouped based upon the associated experiment number.

  1. The lowest lab experiment grade will be dropped.
  2. The experiment grade will be all of the assignments due for a particular experiment (i.e. worksheet; Sapling, Chem21, review and report section; or Sapling, Chem21 and report). On Canvas, the experiments are combined already into the individual Modules.

Quizzes

Quizzes will be completed on Sapling Learning. Additional instructions and information will be posted there.

  1. The due dates for quizzes are given in the schedule. There are no make-up quizzes. All quizzes are due at 5pm on the due date.
  2. Late quizzes will be accepted up to 24 after the original due date and time and will receive a penalty (25% points for quizzes per question answered after the due date). Quizzes will not be accepted after 24 hours.

Pre-lab assignments

Pre-lab assignments will be completed on Sapling Learning. Additional instructions and information will be posted there.

  1. Pre-lab assignments are designed to help you prepare for lab. They are required to be completed before your lab session starts. Failure to do so will result in your TA asking you to leave, as not being prepared for lab is a major safety hazard.
  2. All pre-lab assignments are due at 5:00pm on the day BEFORE your lab is scheduled to meet. Exact dates are given in the course schedule.
    1. This is based upon student self-enrollment into “Groups” via “keycodes” that correspond to your section number. Choosing the wrong keycode and group may result in you receiving a late penalty on your work that will not be removed.
  3. Any late submission of work on the pre-lab assignments will receive a 25% point deduction per question submitted late. No submissions will be accepted more than 24 hours late.

Lab reports

  1. Lab reports are due at 5:00 pm on the due date given in the course schedule.
    1. Reports submitted after 5:00 pm are considered late.
    2. Late lab reports will be accepted up to 24 hours after the original due date and time and receive a penalty (5 points for reports). Lab reports will not be accepted after 24 hours except in the case of an excused absence. This policy does not apply to make-up labs, due to the tight timeframe for determining final grades.
    3. If you have an excused absence on a day a report is due, your due date will be extended to the next lab meeting.
    4. If you have an unexcused absence on a day a report is due, your due date will not be extended.
  2. Final reports are to be submitted electronically on Canvas within each experiment’s Module. Students are responsible for submitting their work to the correct assignment.  Paper or emailed copies are not accepted.
    1. If you experience difficulties submitting your report to Canvas that are not due to having a previous submission, then you need to contact the HelpDesk at 218help@uky.edu and include a screenshot of the error you are receiving, an explanation of what you are doing, including the SPECIFIC name of the assignment, full name, course and section number, and cc the lab supervisor on the email.
  3. Reports are graded by your TA. The Canvas grading rubric is given to you with each assignment and is made available after the assignment is graded by your TA with feedback.
  4. Your grade should be received within one week of the report due date. If it is taking longer than that, please contact the lab supervisor.
  5. If you think your assignment was graded incorrectly, notify the TA within one week of receiving the graded worksheet or one week from when reports grades are posted on Canvas.
    1. Concerns that cannot be settled through discussion with your TA should be taken to the lab supervisor and must be addressed within one week of the assignment grades being posted.
    2. The lab supervisor has the authority to re-grade reports and will do so with strict adherence to the grading rubric. You will receive the score determined by the lab supervisor, even if the score is lower than what your TA assigned.

Peer Reviews

  1. Peer reviews are completed in your lab. Peer reviews are conducted on Canvas and your draft report must be submitted by the start of your lab period. Canvas will distribute reports to students 15 minutes after the due date. If you are not physically present in lab, your report will not receive points for the peer review.
  2. It is expected that you turn in your own work for this assignment, as it is treated in the same manner as a final report and subject to university policies in regards to academic offenses.
  3. Peer reviews will use the same grading rubric as the final lab experiment. Peers are to provide detailed feedback on each paper their review. Scores are determined based upon the average of your 5 peers’ feedback (5 pts) and the feedback of your TA (15 pts). All scores must be submitted to your TA before you leave the lab. Failure to do so will result in you receiving a zero on the assignment.
  4. If you miss lab on a peer review day, you will need to submit the proper documentation for an excused absence to the lab, following the procedures given in the “Policies – Attendance” section below.
    1. If you have an excused absence for the day a TA/Peer Review is done, you have one week to submit the draft report to Canvas. Do not provide your report to a friend to Peer Review outside of the lab period. I suggest that you submit your report to Canvas before your request is approved. Once your absence is excused, your TA will record your score for the peer review.
    2. If your absence is unexcused, you will receive a zero for the Peer Review.
    3. Peer Reviews in any form or fashion are not to be completed outside of lab.
  5. Students must be present in lab to receive a grade for their peer reviewed report.

Chem21

    1. Chem21labs.com or simply Chem21 is a website-based computer program to grade your calculations as part of data analysis and serves as the data section to your lab report.
    2. Most of the issues students have with using Chem21 result from failing to read all of the instructions on the website. This includes items related to calculations and the appropriate number of significant figures.
    3. Attendance is marked by your TA in Chem21 within 24 hours of your lab meeting. If your TA has not set the attendance within this time period, contact your TA and cc Dr. French on the email.
      1. Late assignments due to the TA not setting your attendance will not be extended. We expect that you have checked that you have access to the assignment within the first 48 hours after your lab meets.
    4. All assignments on Chem21 are due at 5:00 pm on the date given in the schedule.
    5. Late Chem21 assignments will be accepted up to 24 hours after the original due date and time and receive a penalty (10 points for Chem21 worksheets, 5 points for Chem21 assignments). Assignments will not be accepted after 24 hours except in the case of an excused absence.
    6. Correctly calculating answers does not indicate that you determined the TRUE experimental value. Often times you will be asked to compare your value to the literature or accepted value and is an indicator of your success at the experiment. While emphasis not on “getting the right answer” in an experiment, a small number of Instructor Graded items are graded on how close you are to that literature value or how small your deviation in measurements are. It is these items that truly reflect how successful your experiment was. Errors can be minimized by working slowly, paying attention to detail, keeping your glassware clean and being attentive to your work. A formal error analysis of things you KNOW went wrong with your experiment is to be included in your Discussion section of your lab report.

 

  1. Please allow one week from the due date of a Chem21 assignment for your TA to grade Instructor Graded items. If they have not been graded within one week, please contact your TA and the lab supervisor.
