In these years of shortened budgets, teachers are becoming more and more inventive in designing science teaching tools and experiments. This manual contains instructions for building a few such tools, either invented or improved on by teachers affiliated with the Institute for Chemical Education (ICE). The tools are created from low cost and easy-to-find materials. Some of the devices can be used in any classroom, but most of them are more appropriate for middle school and older students primarily because of the advanced concepts they teach, such as spectrometry and conductivity. The contents include: the "One-Dollar" Balance, Conductivity Probe, Magnetic Stirrer, the Piezoelectric Popper, Baster Ball Cannon, Neon Lamp Cord, the BB Board, Mass Spec Demonstration Board, Chromatography Simulator, Rod-Climbing Liquid, and Electrolysis Apparatus. For each tool described, a description (varying in length from 2-11 pages) includes: (1) cost estimates of the materials used and total cost of materials to purchase; (2) construction time needed; (3) detailed list of materials needed; (4) instructions for construction; (5) use in classroom. Appendices include: soldering and other device sources. (JRH)
