Chemistry Comes Alive! Volume 6: Laboratory Techniques, contains more than 600 QuickTime movies and more than 3600 still images that illustrate laboratory procedures and techniques. The laboratory equipment and techniques demonstrated on Chemistry Comes Alive! Volume 6 have been selected to include those that students typically need to learn in general chemistry, analytical chemistry, and organic chemistry courses.

The CD-ROM’s broad coverage of techniques and apparatus is evident from the summary contents. All of the CD-ROM’s content is accessible under the heading Chemistry Laboratory Techniques. Techniques suitable for highly accurate analytical chemistry have been collected under Quantitative Techniques in Volumetric Analysis.

The videos and still images from Chemistry Comes Alive! Volume 6 have been carefully organized to make it easy for you to find what you need. They can be used for pre-laboratory instruction either directly from the CD-ROM or by incorporating them into your own multimedia presentations. They are especially useful for illustrating customized laboratory manuals that are locally written and printed. Often both correct and incorrect techniques are demonstrated. These can be used in lessons or quizzes where students are asked to identify errors in technique or to select the best technique from several possibilities.

How to Use Chemistry Comes Alive!

Each Chemistry Comes Alive! CD-ROM is like a Web site—you can access it with a Web browser such as Netscape or Internet Explorer. You can locate the content you want to use via a:

  • Text-based table of contents.
  • Visual interface that parallels the table of contents.
  • List of keywords.
  • Search for a topic or word.

The CD-ROM includes a link to JCE Online where you can use a complete index of all Chemistry Comes Alive! volumes to find the videos you want to use.

Once you find the videos or still images you want, you can easily bookmark them in your browser for quick, convenient presentation to a class. You can also view movies using the QuickTime Player. Or you can copy and paste them into a PowerPoint or other multimedia presentation or a lesson written in HTML. Directions for doing this are available online. You can use the video freely in your own presentations, but an additional license is required before you place any Chemistry Comes Alive! video on your local WWW server or LAN.

Let us know how you use Chemistry Comes Alive! in your classroom or laboratory teaching. We will share with others all ideas that we receive. If you create a new presentation or lesson using this video, contribute it to JCE WebWare or JCE Software and thereby share it with others.

About the Chemistry Comes Alive! (CCA!) Series

The Chemistry Comes Alive! series includes five additional CD-ROMs (1–5). In each the emphasis is on the chemistry. Reactions and laboratory techniques are shown close up. Only where scale is important can more than the demonstrator’s hands be seen. Most movies in CCA! include a voice-over narration, which is also provided as text on the same page where the video is found. The sound of a reaction or process is included when it is important. Chemical reactions, demonstrations, and laboratory techniques have been chosen because they involve an important aspect of chemistry, involve substances or equipment that are not available in many schools, are hazardous, or cause problems of disposal or cleanup. CCA! content is certain to stimulate students’ curiosity and help them learn. To make it as useful to you as possible, a group of knowledgeable chemistry teachers has divided the CCA! series into several volumes, each of which contains closely related material.
