Educating Excimer: Room to fail

Posted on behalf of Aaron Finke Chemistry lab courses should focus more on method and problem-solving rather than specific techniques, with room for students to “fail” so they can learn from their mistakes. The best approach is to use open-ended experiments that require students to formulate conclusions other than “it worked” or “it didn’t work.” However, these experiments usually require a significant time commitment on the instructors’ part, and so these kinds of experiments are usually only found in labs for chemistry majors with small student enrollments. My undergrad’s senior capstone project for chemistry majors is a particularly good example  … Read more

Sugar Daddy: Not so boron after all

With the changing of the guard in Washington, late-night night television hasn’t quite been the same. I guess the new guy in charge is a harder target for comics. Anyway, to a certain extent, the late-night hosts have been turning their attention elsewhere, and eventually chemistry was bound to make it. In this clip, Conan O’Brien draws attention to, among other things, the discovery of a fourth form of pure elemental boron.  Read more
