Tentative course schedule - CH201 - Summer 2019

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;
  • Watching some short videos (links in the schedule below are to helpful review videos that you should watch before lecture); and
  • Reading additional parts of the lab manual (LM), or the writing guide (WC) at the end of the lab manual.

Also, make sure to prepare for upcoming technique workshops during the labs by working through the sections in the Appendix for each technique/skill before arriving at the lab.

Date Details
M 5/20 No classes today

Recorded welcome lecture will be posted
  • Read section on "Professional standards" (LM)
Lecture on lab 1: tools, techniques, and approaches in quantitative analysis
T 5/21 Lab check-in, safety tour, and orientation (in the lab)
  • TopHat assignments on Professional Standards due before NEXT LAB
Lab #1: Tools of the trade for quantitative labwork
               (post-lab for lab #1 is due two hours before the start of lab on 5/23)

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 one-on-one workshops on each technique. Before lab 1, 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).
When lab 1 is complete (and submitted), review basic statistics and data handling (also see Top Hat):
W 5/22 Lecture on lab 2: estimating molecular size (and experimental design)
  • Make sure to complete the reading/watching related to lab 2 that is listed above
  • Preparing lab research notebooks (LM section on Notebook and Assignments, video)
  • TopHat pre-lecture assignment is due 1 hour before lecture (this will typically be the case for each lecture, unless otherwise announced)
Feedback:
  • The lab TFs provide detailed feedback and guidance on the post-lab assignments
  • Typically, TFs make an effort to have the feedback available by Tuesday evening of the week following submission
  • 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"
R 5/23 Lab #2: Determining the surface area of a molecule of stearic acid
               (post-lab for lab #2 is due two hours before the start of lab on 5/28)

Techniques:
  • Glassware and measurement fundamentals (LM: Appendix A.2)
  • Glass transfer pipettes (LM: Appendix A.5), and
  • Vacuum filtration
Self-assessment of 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.
