Unified Technical Concepts (UTC) is a modular system for teaching applied physics in two-year postsecondary programs. This UTC classroom textbook, consisting of 14 chapters, deals with physics for technicians. Addressed in the individual chapters of the guide are the following topics: force, work, rate, momentum, resistance, power, potential and…

Describes a single technique for an enzyme assay of catalase. The method shows that vegetable seeds submitted to pre-sowing 'hardening' cycles of imbition and drying have greater catalase activity and more rapid germination than do the controls. (LS)

Describes the contents of a BIOS i Kit as: (1) guide to initial learning possibilities; (2) state of knowledge articles; (3) sample materials for observation, identification, and/or experimentation; and (4) evaluation materials. (LS)

Describes sources and housing of laboratory rats for use in investigating behavior. (LS)

Describes the apparatus of a chemistry kit that also contains a pupil's manual and a teacher's guide. (LS)

Describes how to construct thin layer chromatography apparatus by using a sheet of glass, glass strips, epoxy resin and a chromatographic plate. (LS)

Describes an experiment demonstrating genetic transformation that opens up many areas of laboratory work and discussion with students. (LS)

Gives a brief survey of the different versions of the air trough and related devices. Presents some of the applications of this equipment in the teaching of the concepts of inertia, acceleration, and velocity. (GS)

This 12-chapter book examines different phenomena as viewed by those trained in physics. These views (or vistas) are promulgated to demonstrate that the infinite variety of things seen in the material world can be reduced to a handful of general laws and to share with the public the richness of the scientist's world view. The phenomena examined…

Concluding the story of Countesthorpe College, the author looked at the results of Britain's most wholehearted experiment in state secondary education. (Editor/RK)

Feeling that projects in chemistry could be used effectively to enhance appreciation of chemistry, a project-based course for the first-year sixth formers was developed in 1973 and because of its success another was organized. Projects from both courses are described. (EB)

Describes the preparation of a compound that is of particular interest because of its sandwich structure in which the metal atom is sandwiched between two planar C5H5-rings. Sublimation results in the formation of long thin plate-like crystals. (GS)

Describes the commercial uses, industrial production and laboratory production of 2-methylpentane-2,4-diol. Suggests extensions for the experiment in the areas of boiling point/composition curves and alkaline depolymerization. (GS)
