REVIEW:
Nanotechnology is the study of manipulating materials on an atomic or molecular scale, especially to build microscopic devices. This could revolutionize the way almost everything is designed and made. This Web site provides materials and information for understanding more about this technology and what it could mean to the world. Educators will find lesson plans to help them incorporate nanotechnology into high school chemistry and middle school technology classes. A variety of topics are covered, such as x-ray diffraction, scanning probe microscopy, light-emitting diodes, and ferrofluids at the high school level, and memory metals, magnetism, and "how we see what we cannot see" at the middle school level. There is a guide to the educator materials, which lists the grade levels of the lesson plans and provides a description of what each plan offers. If all this isn't enough, there is also a Cineplex of movies, a video lab manual, and a slide show library.
