PhET Simulations:

These programs help simulate a variety of topics that we discuss in the course. We frequently use them in class, but they are also provided here for your own, personal, use. Note: Many of these simulations require Java to be installed on the computer you are using them on.

Crash Course Chemistry Videos:

These videos come from YouTube's "Crash Course" channel. In them, Hank Green covers the material of a typical introductory course. Please note that these videos are presented, sorted by unit, but that the sequence within each page is not the same sequence as the instructional sequence for the unit. Also note that these videos contain additional material that is not discussed in class, and that there may be material covered in class that is not specifically discussed in these videos.
