THE SECOND IN A SERIES OF17 VOLUMES, THIS VOLUME PROVIDES THE FIRST GRADE TEACHER WITH A GUIDE TO THE REORGANIZED SCIENCE CURRICULUM OF THE MINNEAPOLIS PUBLIC SCHOOLS. THE MATERIALS ARE INTENDED TO BE AUGMENTED AND REVISED AS THE NEED ARISES. A CHART INDICATES CONCEPT TO BE TAUGHT IN GRADES K-3 FOR EACH OF THE FOUR AREAS AROUND WHICH THE PROGRAM…

Discusses the effects of fiber-optics and other new technologies on communication technology courses. Explores several of the technologies that are applicable to this type of course. Describes how various applications can be presented and highlighted using inexpensive classroom demonstrations. (TW)

Discusses the problems of increased noise levels when using microcomputers as interfaces to chemistry laboratory instruments. Describes how to properly connect a laboratory instrument to a microcomputer's A/D converter board. Suggests how to obtain an analog signal free of interference noise. (TW)

Describes an experimental setup using a microcomputer for demonstrating the circadian movement of petioles. Discusses experiments that were performed using this apparatus and factors that relate to these plant movements. Includes graphs that have been obtained. (CW)

Provides a running commentary on a chemistry instructor's first day in a first course in chemistry. Focuses on the use of fire and chemists' attempts to explain this phenomenon. Provides the ongoing descriptions of the experiments, a summary of the observations, and the key comments made by the instructor. (TW)

Recounts the experiences of a student with cerebral palsy in a college-level, first-semester chemistry laboratory course. Explains how a laboratory assistant worked with the handicapped student in assembling apparatus and manipulating some of the smaller equipment. Discusses the outstanding work performed by the student. (TW)

Dicusses the use of the separatory cylinder in student laboratory experiments for investigating equilibrium distribution of a solute between immiscible phases. Describes the procedures for four sets of experiments of this nature. Lists of materials needed and quantities of reagents are provided. (TW)

Describes two examples where synthetic salt-base mixtures are used in a microscale organic laboratory program as a simple and quick procedure for carrying out Wittig reactions. Both experimental procedures are outlined and discussed. (TW)

Reports on a chemistry laboratory accident intervention study conducted throughout the state of Colorado. Addresses the results of an initial survey of institutions of higher learning. Discusses some legal aspects concerning academic chemistry accidents. Provides some observations about academic chemistry laboratory accidents on the whole. (TW)

Describes a teacher's system for rotating chemistry laboratory exercises in an effort to teach the basic laboratory techniques with a minimum of equipment. Outlines the basic techniques and procedures taught during a two-week rotation schedule. Lists advantages of this approach and guidelines for scheduling. (TW)
