Vernier data collection equipment is featured in the Holt Science Spectrum® lab books. HRW has two books in this series. One is called Holt Science Spectrum — A Balanced Approach. The other is called Holt Science Spectrum — A Physical Approach. A technology-based lab manual was written for each book, and the manuals use the original CBL. The teacher’s manuals have lists of equipment for CBL-compatible equipment. Even though the labs were developed for the original CBL, they can be performed with the LabPro or CBL 2. The only changes that need to be made are getting the right calculator software and the correct set of equipment.

Calculator program
The labs use the PhySci program, which was written for the original CBL. To perform the labs with CBL 2 or LabPro, you will need an updated version of PhySci. This version is available on the Vernier web site at:
http://www.vernier.com/legacy/cbl/progs.html

You will know if you have the correct version by looking at the date on the program’s introductory screen. Depending upon the calculator, the date will either be 7/24/2000 or 7/26/2000 or newer.

Equipment
The equipment lists in the teacher’s manuals are out of date. The following are updated equipment lists for each manual. The list represents one set of equipment needed to perform each experiment in the lab manual. Please note that this list does not include a TI graphing calculator. These lists include the CBL 2 interface. It is also possible to use the LabPro interface, but the equipment list would be slightly different. Contact Vernier if you have further questions.
