In this article, the authors provide a brief overview of the emerging field of nanoscience and why it is an important area of education. They next explain the science behind the new nanoparticulate sunscreens, describe the different elements of the unit, and reflect on some of the opportunities and challenges of teaching nanoscience at the high…

The use of complex instruments for chemical analysis is becoming increasingly important. Unfortunately, because of school budgetary constraints, many students are not exposed to these methods until they reach the college level. When students do have access to sophisticated instruments, they often view them as black boxes, with little or no…

Macrolab (located at New Jersey Institute of Technology) develops devices, training models, and experiments for the scientific education of handicapped students. The construction and operation of a spectrophotometer for blind and visually impaired students are discussed. Construction details are available from authors. (JN)

Describes an apparatus (called the "Rainbow Cup") used for demonstrating the colored rings produced by constructive interference in soap films. Discusses construction of the Rainbow Cup and gives hints for its use in the classroom, especially in relation to classroom humidity. (JM)
