Lecture Demonstration 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 from George Bodner (gmbodner@purdue.edu).

Each sheet provides a brief description of the materials used in the demonstration, 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.
