Traces the history of using mice for medical research and discusses the benefits of using these animals for studies in bacteriology, virology, genetics (considering X-linked genetic homologies between mice and humans), molecular biology, immunology, hematology, immune response disorders, oncology, radiobiology, pharmacology, behavior genetics,…

Suggests a simple technique for collecting and observing human hair roots to compare structure, function, and variation. Students extract their own hair samples and view them using a 40-power microscope objective. Differences between active/inactive phases of hair growth are readily observed. (The activity can be adapted for younger students.) (DH)

Examines President Ronald Reagan's visit to the Wilco Area Career Center (Romeoville, Illinois).

Discusses issues and problems related to the rapidly decaying research infrastructure and the improvement of research facilities and equipment. Although remedies to the problem vary, university spokesmen contend that the federal government's major role in funding educational facilities in the past leaves an obligation for assistance now and in the…

Project CHEMLAB has prepared a database which focuses on laboratory experiments suitable for high school through graduate or professional school levels. The scope of the project, the structure of the database, database features, and computer searching are discussed. (JN)

The value of the genus Nematodius in teaching is not widely realized. Presented is a brief biological outline of the organism (including geographical distribution and reproductive cycle/behavior) and its use in student investigation of selective predation. (Author/JN)

Describes a series of experiments which use a modified automobile alternator as a portable source of three-phase alternating current. The low frequency capabilities of this source allow the phase relationships to be demonstrated using an ordinary galvanometer. (GS)

Describes a simulated laboratory research project in which the thermodynamic and kinetic aspects of ammonia synthesis are simulated on a computer. (MLH)

Surveys the development of two-year colleges and their libraries. (PF)

Listed, with comments and descriptions, are the addresses of suppliers of crystal and molecular models. Included are United States and English suppliers. (SL)

Presents the results of a survey of English physics teachers concerning the percent of classroom time they spend in practical work, the objectives of practical work, and their use of student projects. (MLH)
