. As recently as a few years ago it was popular to regard nanoscience and nanotechnology as fads that would pass. I recall, for example, being chided by some for using the term “nanoscale” in a first-year college chemistry textbook. But this is one fad that is not passing–at least as measured by the rapidly increasing number of undergraduate degree programs in nanoscience and nanotechnology. During the past three years the number of programs has increased by more than 100 and there are now more than 250 programs in 25 countries (see http://www.prweb.com/releases/nanowerk/nanotechnology_degrees/prweb4134154.htm). This is important with regard to how we teach both high school and first-year college chemistry, because students who are expecting to enter the nano fields will benefit from learning the many important ways that chemistry contributes to those fields, the many careers in such fields that are open to those who major in chemistry, and how such fields are important in solving problems such as the energy crisis. More nano in chemistry courses is certainly warranted. High school teachers who want to learn more nanoscience should check this URL:http://www.cel.cmich.edu/nanosci/.
