Lecture Demonstration Movie Sheets

Lecture Demonstration Movie Sheets

NOTE: The set-up and preparation information for most of these demonstrations is available in the Lecture Demonstration Manual by Bodner, Smith, Keys, and Greenbowe. John Wiley and Sons, Inc. (http://www.wiley.com) prints updated editions on an irregular basis. Copies might also be obtained by contacting George Bodner (gmbodner@purdue.edu).

Each sheet provides a quicktime video of the demonstration, a brief description of the materials used, pictures of the equipment used, observations, and explanations. All of the sheets are available from here, and sheets pertinent to a specific class can be made available via the course homepage.

Sheets described as "Under Construction" have no movies associated with them yet, but can still be useful for descriptions and reference material in the interim. To view the demonstration sheet index directly (i.e. without movie and link frames), go to http://chemed.chem.purdue.edu/genchem/demosheets/index.html. In addition, sheets that are marked "obsolete" can still be found at this location.

Please note that the movie sheets contained on this page are only viewable if your browser supports frames!
