Tentative course schedule - CH111 - Fall 2021

Preparing for Lectures:

You will get the most of lectures if you have done the appropriate preparation beforehand. In this course, the preparation ahead of lecture will include:

  • Reading the lab that will be discussed (PDFs will be posted on Blackboard);
  • Working through the Top Hat pre-lecture assignments (posted on Top Hat);
  • Watching some short videos (videos are included in the Top Hat assignments); and
  • Reading additional parts of the lab manual (LM), or the writing guide (WC) at the end of the lab manual (all posted on Blackboard).

Lab techniques:

New lab skills and techniques are also highlighted in the schedule. Make sure to prepare for upcoming labs by working through the sections in the Appendix for each technique/skill before arriving at the lab.

Date Details
Thurs 9/2 First day of classes.
Tues 9/7 Introductory lab lecture -- welcome to the course (pre-recorded lecture)
Wed 9/8 Lab check-in: students meet their lab TF in the lab at the start of the lab section for check-in and a safety discussion. All students must bring with them and wear the following at all times:
  • Face-forming goggles
  • Lab coat
  • Face mask
Students will work on a short assignment after check-in (on Top Hat)

Wed 9/22 Lab #2: Determining the surface area of a molecule of stearic acid
             (post-labs are due two hours before the start of next lab, unless otherwise noted)

Techniques: as new techniques are being introduced in lab, you will be asked to work through the section of your lab manual about each new technique before lab. Then, in lab, there will be workshops on each technique. Before lab 2, please make sure to review the material about:
  • Laboratory practices (LM: Appendix A.1)
  • Micropipettes (LM: Appendix A.4), and
  • Balances (LM: Appendix A.3; skip A.3.2 and A.3.4).
Self-assessment of post-lab assignments: technical documents, especially in the sciences, can be challenging to perfect -- that is normal. A detailed rubric designed to help you polish your work is posted under "Course Documents" in blackboard. Use the "Post-lab Assignment Rubric" to help you assess and refine your work on the post-lab assignment that is due next week.
Mon 9/27 Feedback:
  • Lab TFs provide detailed feedback and guidance on the post-lab assignments
  • Typically, TFs make an effort to have the feedback available by late Monday or Tuesday of the week following submission
  • Feedback on the post-lab assignment for lab #1 should be posted by today
  • Imporant details on how to access and interpret the feedback are presented in the "Turnitin Assignments - Getting Feedback" document posted on blackboard in the "Course Documents"
