Chem 202 labs meet from 1:10-5:00 PM, MTuW. Please arrive a few minutes early so that you can drop off your stuff and be ready to receive in-lab instructions at the start of lab. Actual lab work may not begin before 1:10.
Lab lectures meet from 6:10-7:00 PM, Th. Lab lectures will take place every week unless announced otherwise.
A tentative semester schedule for Chem 202 lab work is listed below. You should expect that adjustments will be made to the information below as we move forward. Changes to the schedule will be announced in the usual ways: lab lecture, mass email, 202 Moodle site.

A tentative semester schedule for Fall 2010 Chem 201 lab work is listed below. Notice that there is something to do every week until after Thanksgiving break and also that several experiments will take more than one week (session) to complete. Last-minute changes to the schedule will be announced in the usual ways: lab lecture, mass email, and/or 201-202 wEB pAGE.
Because of routine uncertainties about lab registration, we will not perform any experiments during the first week of classes, but you are still required to attend one lab session this week and roll will be taken.
Labor Day. The Monday lab will not meet because of the holiday. Monday students may attend a different lab session. If necessary, we can also open the lab on Thursday to accommodate Monday students (if you need to make use of this option, please contact the instructor in advance).
Thanksgiving break & beyond. The synthesis of acetylferrocene is the last scheduled experiment. Because of Thanksgiving break, Friday students will need to complete this experiment after the break. The lab will be open on all of the usual afternoons and Friday students may "drop in" to any lab.
