Reviews the historical development of thermometry and the origins of the Fahrenheit and Celsius temberature scales. (CS)

A study was conducted to determine the extent to which departments of industrial education are offering courses which assist students in becoming technologically literate. Two types of classes are being offered: (1) technology as a discipline and (2) the tools, materials, and processes of industry, but general courses were not widely available.…

Argues that laboratory schools go awry because their goals and purposes are not clear. Underscores the major difficulties and hazards bearing upon laboratory schools: problems of function, differing values, and external and internal support. Proposes constructing or re-creating these schools through dynamic, forward-looking, inquiry-sustaining…

Discusses some examples of Fresnel diffraction. Diffraction effects caused by round holes, round obstacles, narrow slits, narrow obstacles, and transparent obstacles are included. (HM)

Presents computer assisted instruction (CAI) applications involving prelab simulations of organic chemistry experiments in advance of performing the actual experiments. Tables present the PLATO lessons used in the laboratory; and a comparison of average times for students to complete laboratories with and without the PLATO system. (CS)

Describes an undergraduate physics experiment for studying Curie temperature and Curie constant of a ferromagnetic material. The exchange field (Weiss field) has been estimated by using these parameters. (HM)

Lists questions that teachers should ask relating to use of all chemicals in the school laboratory, as well as chemicals with known and suspected dangerous properties. Tables list Occupational Safety and Health Administration (OSHA)-defined carcinogens, American Chemical Society-defined teratogens, suspected carcinogens, and other hazardous…

Describes the basic procedures for use of an electron-spin resonance spectrometer and potassium azide (KN3) in an experiment which extends from the phase of sample preparation (crystal growth, sample mounting, and orientation) through data taking to the stages of calculation and theoretical explanation. (Author/DS)

Described is the use of cleavage as an aid to microscopic determination of unknown minerals by immersion methods. Cleavages are examined in relation to fragment shapes, types of extinction, and cleavage-optical relationships. (Author/DS)

This article describes an introductory physics laboratory program which teaches three skills: (1) the ability to make estimates and order-of-magnitude calculations, and to use these to check experimental work, (2) the ability to use qualitative and quantitative statistics, and (3) the ability to describe an experiment in one's own words.…

Suggests how an unused portion of the schoolyard can be inexpensively transformed into an environmental study area and outlines some plant study activities for students. (SJL)

The vocational accounting laboratory is a viable, meaningful educational experience for high school seniors, due to the uniqueness of its educational approach and the direct involvement of the professional and business community. A balance of experiences is provided to match individual needs and goals of students. (CT)

The author, the president of Amoco Venture Capital Company, a subsidiary of Standard Oil Company of Indiana designed to promote minority purchasing and finance minority enterprise, describes his program and the national program to promote minority enterprise. Ways that research administrators can develop minority sources for laboratory needs are…

A significant portion of the increase in medical care costs results from the inefficient use of clinical laboratories by some physicians. A course for the undergraduate medical curriculum that will introduce students to the practice of intelligent and cost-effective utilization of the clinical laboratory is proposed. (MLW)

Described are Charles W. Eliot's contributions to science education and academia. Eliot's achievements include changing college admission standards and support for laboratory courses in physics, chemistry, biology, and geography. (DS)
