We will have excellent guest lecturers. Stay tuned.


While we will use Brown, Lemay, and Bursten, 7th edition (the same book as used in Chem 12, 12H, and 13), we will also use much supplementary material and www links.

Learning in Chem 13H

This is an exciting course for many reasons. We are able to cover many of the highlights of chemistry in a relatively informal way. This introduction is meant to guide you through many future years of scientific thinking and discussion, citizenship, and possibly even more chemistry.

Much of what you learn, you will learn on your own or from each other. This will allow us greater latitude in class. For instance, nearly every Friday class will be a discussion. If you have topics to discuss and know in advance, let us (instructors and classmates) know so that we can prepare for a higher level discussion.

While we will cover everything in the regular (Chem 13) version of this course, we will do it faster (!) in order to allow us to pursue many other additional topics. This will require a great deal of work on your part. Please be prepared for it and budget the time for it. Anticipate that the lectures, the readings, and the homeworks will be complementary rather than overlapping. You will be responsible for the material from all of these sources. Similarly, your participation in class is required both for discussions and for the education of your classmates and professor. There is little that we plan to say that is so critical that a good classroom discussion would not be preferable.
