The Lecture Demonstration Facility provides instructors with resources that will enable them to illustrate chemical principles behind their lecture materials and, in so doing, hopefully engender a greater understanding of those principles.
Joe Franek is the Department of Chemistry's lecture demonstration director.
We have a variety of models available, including:
- permanent models of metal atom packing, salts, organic and inorganic compounds; and
- numerous model kits to build simple compounds in class.
Request a model by sending an email to email@example.com.
- Illustrating a number of demonstrations, subjects and laboratory techniques.
- Computer Interface
- Allows the measurement and screen projection of pH, temperature and pressure.
- Allows small items or demonstrations to be screen projected for viewing by large classes.

Request a demonstration by sending an email to email@example.com. Some of the demonstrations are available on the Microsoft Word or PDF downloads.
