Tested Demonstrations (TD) is not only one of this Journal’s longest running features, but also one of its most prodigious. More than 1,000 articles and tidbits have been published under its banner since 1955. This information about chemistry demonstrations can be better organized and updated through the digital medium. For example, modern safety precautions or improved procedures for many published demonstrations are available, but they are not easy to find. The static nature of the print medium makes it impossible to update an article to include such information, but the digital medium provides the opportunity to do so. JCE DigiDemos aims to provide a rich and dynamic environment for learning about chemistry demonstrations.

The JCE DigiDemos Community

Each JCE DigiDemo is published online in a format such that you and other teachers and demonstrators can make suggestions for enhancing or expanding the demonstration. Your comments may concern improvements or variations on the procedure or novel ways of presenting the demo. Many demonstrations have “real world” applications that were unanticipated at the time they were written, and we hope readers will point out these connections, as well as links with other areas of the chemistry curriculum, or even with other disciplines. While TDs are checked for safety, it is impossible to anticipate risks that may arise in the almost infinite variety of local conditions that surround each performance of a demonstration, and we intend that safety issues will be reported for each demonstration. Links to Chemical Laboratory Information Profiles (CLIPs), which summarize the properties of substances required by the demonstration, will be part of the collection.

In future months, we will be adding to JCE DigiDemos many of the demonstrations that have already appeared in the Journal of Chemical Education. In many cases, the demonstrations will be supplemented with videos, graphics, and safety information that did not appear in the originals. A search engine to help find the demonstration perfectly suited to enlivening any topic is under development, as well as a demo browser/locator modeled after a table of contents typical of general chemistry textbooks, with direct links to demos suited to each topic.

JCE DigiDemos Discussion Forum

We encourage you to visit the JCE DigiDemos collection of the JCE DLib. There you will find a link to the JCE DigiDemos discussion forum. If you haven’t participated in a discussion forum before, instructions are provided at the site. Here you will find direct links to this month’s demonstrations. A preliminary version of the Table of Contents browser is also there with an invitation to add your comments. Our invitation is always open to contact us directly with your comments and suggestions, and of course, to submit manuscripts describing demonstrations you develop to the JCE DigiDemos: Tested Demonstrations feature.
