The science education budget of many secondary schools has decreased, while shortages and environmental concerns linked to conventional Science Education Equipment and Materials (SEEMs) have emerged. Thus, in some schools, resourceful educators produce low-cost equipment from basic materials and use these so-called improvised SEEMs in practical…

The construction of a simple volumetric adsorption apparatus is highlighted. The setup is inexpensive and provides a clear demonstration of gas phase adsorption concepts. The topic is suitable for undergraduate chemistry and chemical engineering students. Moreover, this unit can also provide quantitative data that can be used by young researchers…

Although the development of next-generation (NextGen) sequencing technologies has revolutionized genomic research and medicine, the incorporation of these topics into the classroom is challenging, given an implied high degree of technical complexity. We developed an easy-to-implement, interactive classroom activity investigating the similarities…

Between 1880 and 1920 the way science was taught in American High Schools changed dramatically. The old "lecture/demonstration" method, where information was presented to essentially passive students, was replaced by the "laboratory" method, where students performed their own experiments in specially constructed student laboratories. National…

Presents three notes on new equipment, techniques, or materials of interest to teachers of physics. (HM)

While science films can differ widely in their content and purpose, the making of such films rests on a pattern of principles, techniques, and matters of routine. This book traces that pattern and presents descriptions of how some particular problems were tackled previously. The history and state of the medium are overviewed, with information on…

Explained is a representation of the three categories of spectra. Discusses what a lesson on spectra should include, background information, and equipment needed. Provided is a diagram of an absorption box. (RT)

Any effort to reform science education in the schools must include input from the nation's science teachers concerning what they need to do in order to improve instruction and student performance. Science teachers in rural schools have many needs that differ from those in more urbanized areas. A survey of science teachers in Arkansas, Illinois,…

Describes modifications and procedures needed for parasitic lampreys to be kept in a closed system. Presents information dealing with obtaining the organisms, tank modifications, temperature, feeding, disease prevention, and animal welfare. A discussion is included. (RT)

Proposes the V-Scope as a teaching aid to measure, analyze, and display three-dimensional multibody motion. Describes experiment setup considerations, how measurements are calculated, graphic representation capabilities, and modes of operation of this microcomputer-based system. (MDH)

Describes two examples where synthetic salt-base mixtures are used in a microscale organic laboratory program as a simple and quick procedure for carrying out Wittig reactions. Both experimental procedures are outlined and discussed. (TW)
