Chem 115 Lecture slides

Lecture Slides

Below is a mix of copies of last year's and this year's lecture slides (please note dates). This year's lecture slides will be posted at least one day prior to each lecture and have 2008 dates posted with them. In the meantime, previous years' lecture slides will remain posted for lectures we have not arrived at yet, in case they may be helpful to you in working ahead in the material.

These lecture SLIDES are not lecture notes. The lecture slides are mostly graphs, equations, drawings, pictures, and analogies which serve as discussion points during the lecture, as well as problems posed that will be solved during lecture. You may find it useful to bring a printout of the lecture slides with you to lecture to take notes on. The lecture slides are usually not a good substitute for attending the lecture and taking notes. If you miss a class, there are notes posted that other students have taken during class. It would also be to your benefit to find a classmate and go over the notes with him/her.
