General Chemistry I Digital Lecture Material

Screencasts are flash video files that contain the powerpoint presentation and an audio track. These were recorded in my office (not lecture) so they are short, but very dense.

If you wish to download these files, click on the google video link. 

Note: these are NOT meant to replace the chemistry lectures, they are meant to augment them.
