This selected collection of How-To-Do-It articles published in the American Biology Teacher during the past six years presents experiments that can be conducted safely under properly trained and responsible teacher supervision. Contents include: (1) "General Biology and the Nature of Science"; (2) "Cells and Molecules"; (3) "Microbes and Fungi";…

This handbook was prepared to help science teachers, administrators, and other school staff members understand and avoid situations in which accidents might occur in the science laboratory, on field trips, or during outdoor education experiences. Suggestions contained in this publication are generally agreed upon and recommended for consideration…

This bulletin responds to frequent requests for practical information relating to equipment and supplies for teaching science in small high schools. Laboratories for science courses have been for several decades necessary parts of every high school teaching the sciences. This bulletin is a brief survey of the necessary equipment to teach the…

Discusses the use of two television sets with UHF coverage and a window screen or aluminum foil reflector to conduct a take-home experiment in physics. (CC)

Describes several sources of error in a sampling and analysis procedure for oxides of nitrogen from stationary sources (Method 7, Federal Register, 1971), and provides methods for resolving these errors. (JR)

Discusses the importance of children developing personal associations with animals, and suggests that it is the responsibility of schools to teach students how to properly care for pets. With particular reference to Canadian experiences, criticizes the widespread neglect of pets and misuse of animals in school laboratories and science fairs. (JR)

Features of a biology demonstration laboratory designed to handle large number of students and provide opportunities for using materials including live specimens for practical work are described. The design of the demonstration laboratory is given. (PS)

Describes a laboratory method suitable for senior high school classes for investigating possible mechanisms of catalytic function. The Harcourt-Essen reaction is used to demonstrate a catalytic process that can be investigated quantitatively by standard kinetic methods. (JR)

Suggests that the Friedel-Crafts reaction, used for synthesizing a wide range of aromatic compounds, is an ideal vehicle for extended senior high school project work in chemistry. Provides a theoretical discussion of the reaction, suggests a number of suitable investigations, and outlines the experimental details. (JR)

The use of 10cc. syringes in high school chemistry experiments can reduce the expense of equipment and lead to imaginative experimental designs. Describes the equipment and experimental procedures for four experiments utilizing syringes. (JR)
