We will have excellent guest lecturers. Stay tuned.
While we will use Brown, Lemay, and Bursten, 8th 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 much 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.
Unlike other general chemistry classes, we will cover how it is that we know what we think we do and how we test that understanding. We will develop an understanding of what experiments and theory are required to answer fundamental chemical and scientific questions.

600 PM Elements of Life Poster session -- 2nd Floor Osmond/Davey overpass.
You will have four minutes to present followed by one to two minutes of discussion.
A few thoughts:
Keep a single focus.
Practice your presentation out loud! Work through rough spots repeatedly (memorize words if necessary).
Props and assistants are ok, if justified by your presentation.
Use large, readable fonts. More detail can be in your presentation than on your poster.

Discussion Topics Suggested
Chemical and biological warfare agent detection.
Bring in topics to discuss. These can be aligned to the topics we are covering, but do not need to be. If we can discuss them intelligently, we will do so. If not, we will find some references and cover them next week. Every Friday class will work this way.
Germline modification of primates.
Genetically modified animals on Yahoo.
Fullerenes and like molecules.
Green fluorescent protein labeling.
Drugs of abuse.
Memory in the brain.
1. Class participation: 20%Paper Requirements:
2. Homework: 10%
3. Paper and poster presentation of researched topic (elements of life -- specific elements will be assigned in class): 20% (10% each)
The paper should be approximately 10 pages in length, double spaced (double spacing is important to leave room for my comments) in a 12 point font, with 1" margins all around. The paper should include figures and complete references (not www references). The figures will not count in the length. Please take into account the comments that you get from your presentation in preparing your paper.
4. One in-class exam (1 hr) and one poster on materials: 30% (15% each)
Note that pre-approved make-up or conflict exams will be oral exams.
No paper is required for this second poster.
5. Oral final exam: 20%
If you received less than 85% of the homework points, your final exam will be a rigorous test of general chemistry with special emphasis on the homework that you missed!
