The Task Force responsible for this document was established to study 2 major questions: (1) How should the minicomputer be used in the undergraduate classroom and laboratory program? and (2) What type of minicomputer facilities are needed to carry out the recommended program? The first question is treated in Part 1. Two types of applications are…

This booklet is one in a series of instructional aids designed for use by elementary and secondary school science teachers. The various units and forms of radioactive materials used by teachers are first considered. Then, the quantities of radioisotopes that a person may possess without a license from the Atomic Energy Commission (AEC) are…

Described is a qualitative analysis laboratory procedure for high school chemistry students. The paper received the Science Teaching Achievement Recognition (STAR) award. The procedure acquaints students with certain ions and uses the knowledge of ions to devise a flow-chart for separating and identifying these ions in an unknown solution. (SL)

Describes ion-exchange methods for the qualitative determination of iron (III), chromium (III), aluminum (III), and manganese (III) and (IV) in the presence of phosphates. (MLH)

Suggests that the anatomy of a green pea be studied as the culminating laboratory activity of a botany unit in a biology course. (LS)

Describes how to assemble a respirometer from common laboratory materials for quantitative measurements of gas production. (LS)

Gives basic instructions for rearing several readily available insect species particularly well suited to use in secondary, and even elementary, school classrooms and laboratories. (LS)

Includes description of a light meter, photometer, fluid flow apparatus, and acoustic grating. (RH)

Describes some laboratory apparatus and demonstrations; describes an electronic device to illustrate an octave synthesizer; shows how to get negative changes from an electrophorous; explains a body levers device to clarify the principles of moments and levers; and finally shows how to demonstrate acceleration in simple harmonic motion. (GA)

Describes a few apparatuses and demonstrations for teaching physics under the headings: demonstrating resonance of the inner ear, constructing a potential well-hill for overhead projectors, rubber tube vacuum pump, improvement on the simple homemade motor, air track to demonstrate sailing into the wind, and center of gravity and stability. (GA)

Stresses the importance of safety in school laboratories. Describes a state program to inspect chemistry laboratories in order to correct unsafe conditions in them. Advocates safety courses for teachers in their training. (GA)

Describes a laboratory experiment designed to give beginning physiology students a successful experience with neurophysiological Techniques and to demonstrate some properties of sensory neurons. Pin electrodes are used to record extracellularly from mechanoreceptors in a cockroach leg. (Author/MA)

Describes a simple device to improve the set retrieval of spilled mercury. (SL)

Discusses the development of materials used in chemical laboratories. (SL)

Describes a reaction system experiment utilizing saponification of ethyl acetate by sodium hydroxide. The activity is part of an undergraduate chemical engineering course. (SL)
