Presented is the draft form of a handbook for science teachers in the secondary technical schools of Victoria, Australia. This handbook is designed to provide teachers with information concerning the administration and operation of the Technical Schools Division, with information concerning safety hazards, liabilities, and procedures in science…

Describes the electronic circuitry which can be used to demonstrate the buildups of Poisson distributions with very high precision. Analysis of the data obtained is included in the paper. (CP)

Describes a method in which glass plates are coated with adsorbent, using a technique which is cheap, rapid, and reliable; avoids the need for expensive, commercially-available thin layer chromatography equipment. (MLH)

Presents several new products and equipment for teaching college science courses such as the electronic toploading balances and the hologramaker. A description of each product, cost, and addresses of manufacturers are also included. (HM)

Describes the following: an electric circuit for an expensive photometer, an amplifier circuit capable of demonstrating many aspects of behavior of free and driven oscillators, and finally a projection recording system which uses an unmodified XY or XT recorder and a separate overhead projector. (GA)

Describes the procedure, the circuitry, and the calibration required to convert a voltmeter into a pH meter for use in the physics laboratory. (GA)

Presents guidelines for the construction and maintenance of a life science culture center with mobile and stationary units. (CP)

The basic physical principles of dye lasers are discussed and used to analyze the design and operation of tunable dye lasers pumped by pulsed nitrogen lasers. Details of the design and construction of these dye lasers are presented. Some simple demonstration experiments are described. (BB)

Describes the development of the ion scattering spectrometry (ISS) analytical instruments. (SL)

Describes an apparatus and experimental procedure for quantitatively evaluating the activation energy associated with annealing color centers in glass. (MLH)

The experiment described here involves simultaneous monitoring of pH and NMR chemical shifts during an aqueous titration of alpha- and beta-alanine. This experiment is designed for use in an undergraduate biochemistry course. (MR)

Describes increased sophistication in instrument spectrophotometry. (SL)

Reviews developments in the field of thermal analysis instrumentation. (SL)

Describes a simple device for observing solar spectra, an inexpensive circuit to produce two sinusoidal signals, a method of demonstrating Charles' Law with plastic bags, and discusses the hazards of connecting a vacuum pump to a gas jet. (SL)

Provides an evaluation of the Macbeth Student Spectrophotometer (MSS-100) and describes the use of Slinky toys to demonstrate harmonic motion. (SL)
