Learning to navigate the treacherous shoals of the chemistry laboratory is tricky business. Fortunately, interested parties can use this fine online course from MIT's OpenCourseWare to become more familiar with such matters. The course consists of "intensive practical training in basic chemistry lab techniques" and the site includes a host of instructional videos. The manual and materials for this...
The Chemistry-Based QuickTime, Shockwave Flash, GIF Animations, and Streaming Audio Web site is provided to "support the teaching of concepts in chemistry in freshman through graduate level courses." Dr. Thomas Chasteen's site offers links to multimedia files related to chemiluminescence, gel electrophoresis, how a grating works, gas chromatography and mass spectrometry, titrations, atomic...
It can be tricky to remember the position of lanthanides within the periodic table of elements, but this interactive feature from Annenberg Media's "Interactive" series will keep students in the know about those so-called "rare earth" elements. This particular feature begins with "Atomic Basics", which provides an overview of the atom and its various functions. After completing this section,...
The JCE Chemical Education Exchange offers a range of videos designed for educators and the curious public. Created as part of the larger ChemEd Exchange website, videos include "Boiling by Cooling,” "Atmosphere Pressure,” "Ammonia Fountain,” and "Canned Heat.” All told, the website hosts over 280 videos and several dozen are available at no charge. Visitors can use the search engine on the top of...
After watching this erudite (and fun) program from NOVA, you'll never again wonder "Where's selenium?" This two-hour program is hosted by David Pogue (the host of NOVA's "Making Stuff" program) and it "spins viewers through the world of weird, extreme chemistry: the strongest acids, the deadliest poisons, the universe's most abundant elements, and the rarest of the rare." It's a fascinating way to...
At this website, the University of Minnesota supplies numerous chemistry experiments. The activities are divided into two categories: demos and recipe cards. The demonstrations, which usually require a chemistry lab setting and chemistry supplies, are helpful for chemistry teachers in a classroom environment. The recipe cards, however, can usually be easily performed in the home. For example,...
