This bulletin of Scottish Schools Science Equipment Research Centre provides information about new scientific equipment for use in classrooms and laboratories. The sciences covered are biology, chemistry, and physics. The pieces of equipment can either be purchased from manufacturers or constructed in schools. All descriptions include advantages…

A model demonstrating the relationship between the structure of blood vessels and the flow of blood is described and illustrated in the biology section of the newsletter. The apparatus also contains a functional (but not structural) model of the heart. Suggestions for the preparation of a relatively permanent dialysis bag from visking tubing are…

This project, sponsored by the Jim and Ada Irving Foundation, was keyed to determining the most significant free and low-cost teaching aids needed by the nation's classroom science teachers. Some 2,000 grade and high school science teachers throughout the country were polled on a scientifically sample basis from names listed in the U.S. Registry…

This guidebook contains designs of laboratory equipment considered essential for student investigations in introductory biology in developing countries. The designs presented are based on the premise that many students and teachers will wish to make equipment for themselves. Although all the designs have been tested under laboratory conditions at…

Compiled in this book is basic, technical information useful in a systems approach to pollution control. Descriptions and specifications are given of what is available in ready made, on-the-line commercial equipment for sampling, monitoring, measuring and continuously analyzing the multitudinous types of pollutants found in the air, water, soil,…

Discusses input and output characteristics, basic circuits, and interfacing complimentary metal oxide semiconductor (CMOS) digital logic devices to other devices. (SL)

Discusses some recent advances in telescopes, in particular the design and construction of the Multiple Mirror Telescope in Mt. Hopkins, Arizona. (CP)

Described is the construction and use of an apparatus which applies liquid displacement to the problem of volume determination, giving accurate and repeatable results within 0.1 ml of actual volume measured. The apparatus is easily made from two jar parts, two bottle parts, and a burette. (Author/MA)

A new instrument called the tunneling microscope has recently been developed that is capable of generating real-space images of surfaces showing atomic structure. Discusses current capabilities, limitations, and the physics involved in the technique. Includes results from a study of silicon crystal surfaces. (JN)

Describes a simple apparatus used to demonstrate the thermal conductivity of gases. Procedures for completing the demonstration are included. (JN)

Describes the design and use of a projectile motion apparatus to illustrate a variety of projective motion results typically discussed in an introductory course. They include independence of horizontal (constant speed) and vertical (constant acceleration) motions, parabolic path shape, and other types of motion. (JN)
