This investigative laboratory exercise uses the different relations between ambient temperature and metabolic rate in endotherms and ectotherms as a core concept to answer the following question: What thermoregulatory mode is employed by chicken embryos? Emphasis is placed on the physiological concepts that can be taught with this exercise,…

Describes the design of undergraduate chemical laboratory fume hoods. Proves that folding the sides and top permit the hood and its duct hose to be stored in a standard 18-inch-wide laboratory cabinet. (WRM)

Reviews new science equipment and products for the laboratory. Includes hand-held calculators, fiberglass fume hoods, motorized microtomy, disposable mouse cages, and electric timers. Describes 11 products total. Provides manufacturer name, address, and price. (MA)

For several decades there has been a general concern that the level of research funding for academic instrumentation was not sufficient to keep pace with the requirements of cutting edge research. To develop the factual trend data necessary to understand the depth of the problems in academia and thus provide an adequate response to these concerns,…

Describes a class of ion-selective electrodes that use a solid-state sensing membrane. These are suitable for student activities. (SL)

Describes a device for maintaining the proper water level in knife boats during ultramicrotomy. Water levels in troughs are adjusted rapidly and precisely during the cutting process. Illustrations are included. (Author/MA)

Describes the use of the magnetometer in an introductory undergraduate geology course. (SL)

Presents a description of the National Center for Atmospheric Research, a center where scientists pursue research interests, where research facilities, too large and expensive for any one institution to maintain, are housed, and where unified planning for research is made in response to national and international concerns. (SA)

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…

Reviews the development of accelerators over the past 50 years. Topics include: types of accelerators, including cyclotrons; sociology of accelerators (motivation, financing, construction, and use); impact of war; national laboratories; funding; applications; future projects; foreign projects; and international collaborations. (JN)

A description of the commercially produced Harris Data Memory is presented. Operation instructions, memory capabilities, data storage, and applications are included. Usefulness of the instrument to instruction in all of the sciences is considered. (SA)

Relays one school science technician's experiences in taking a course designed to improve and standardize technician credentials in the United Kingdom. (WRM)

The teaching laboratory in physics departments in colleges and universities is a source of great potential strength in undergraduate education. Recent surveys and conferences, have identified inadequate teaching equipment and laboratory development. This report reviews these problems and offers suggestions for an enhanced federal effort to solve…

Describes an apparatus that uses liquified gases to wash solids. Discusses the procedures and processes used to do a wash with liquid sulfur dioxide. (CW)

Describes the plan submitted by the Nuclear Science Advisory Committee to the Department of Energy and National Science Foundation urging construction of an ultrarelativistic heavy-ion collider designed to accelerate nucleon beams of ions as heavy as uranium. Discusses the process of selecting the type of facility as well as siting. (JM)
