As a "new science," nanotechnology has brought many nanoscale-based applications to the forefront of society. This article describes one such application--a nanosensor that can precisely detect a variety of chemical stimuli in the environment--and presents the science behind it as an interdisciplinary science topic. This article also provides…

Research Experiences for Teachers (RET), funded by the National Science Foundation, offer teachers an opportunity to participate in current, hands-on scientific research in laboratories across the United States. These experiences provide an avenue for teachers to understand the process of research and gain insight on emerging technologies with the…

Points out the important role of scientists in society as educators. Explains problems caused by not understanding the theory of evolution and discusses possible solutions. First published in 1966. (YDS)

Describes an inquiry investigation to enable students to understand water cohesion, surface tension, and heating curves for water. The investigation includes several activities organized in a three-phase learning cycle: (1) exploration; (2) concept invention; and (3) concept application. (DDR)

Describes a yearlong project that involves biology students in monitoring water quality. Includes details of the awareness phase, action phase, and presentation phase. Discusses student reaction to the project. (DDR)

Describes an open-ended, inquiry-based chemistry lab in which students design and construct snow globes. Encourages the development of problem solving skills. (DDR)

Presents an example of a greenhouse-effect experiment from the Climate Protection Institute. Analyzes the amount of carbon dioxide in ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide by titrating with ammonia and bromthymol blue. (MVL)

Describes a three-week environmental minicourse in a general chemistry class. The minicourse consisted of two distinct phases, a one-week introduction to environmental chemistry and a two-week project involving a particular environmental problem. (PR)

Presented is a unified science and technology instructional model that emphasizes multidisciplinary learning through discovery and hands-on activities. Two courses, developed from this model, are described in terms of curriculum, teaching methods, scheduling, credit, limitations, enrollment, and promotion. (KR)

Describes 11 hands-on activities involving genetics; principles of chemical luminescence; a nucleus model; dissection pins; science, technology, and society (STS) courseware; plant dyes; the scientific method; current events; a portable planetarium; solar energy; and burning tests. (YP)
