Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

Describes a survey of experiments including a stringed instrument experiment and discusses other instructional uses of cartridges. Includes information on the characteristics of cartridges. (GH)

This project developed a mobile spectroscopy laboratory, a truck equipped with scientific instruments which can be moved from school to school to provide hands-on experience with instruments normally too expensive for a small school to purchase. A summer conference trained the on-campus participant faculty in the use of the truck-laboratory as…

The study was designed to determine how standard science skill builder activities can be modified or adapted for use by orthopedically handicapped students. Nine secondary level science experiments were selected for initial review and from these, three were selected for adaptation--use of the microscope, use of graduated cylinders, and use of the…

ELEMENTARY SCHOOL PUPILS' ABILITY TO USE EVIDENCE FROM SCIENTIFIC INSTRUMENTS WAS DETERMINED. THE 320 PUPILS FROM GRADES ONE THROUGH SIX WERE PLACED IN DECISION-MAKING SITUATIONS REQUIRING THEM TO USE EVIDENCE FROM A PLATFORM BALANCE OR GRADUATED CYLINDER. PUPILS WERE REQUIRED TO DIFFERENTIATE BETWEEN MASSES OR VOLUMES OF PAIRS OF OBJECTS. THE…

DESCRIBED ARE LABORATORY EXERCISES IN OCEANOGRAPHY DEVELOPED FOR USE IN HIGH SCHOOLS BY THE SECONDARY SCHOOL TEACHERS IN THE 1967 NATIONAL SCIENCE FOUNDATION (NSF) SUMMER INSTITUTE IN OCEANOGRAPHY AT FLORIDA STATE UNIVERSITY. INCLUDED ARE SUCH ACTIVITIES AS (1) THE MEASUREMENT OF TEMPERATURE, WATER VAPOR, PRESSURE, SALINITY, DENSITY, AND OTHERS,…

This booklet is one of the "Understanding the Atom" Series. The science of spectroscopy is presented by a number of topics dealing with (1) the uses of spectroscopy, (2) its origin and background, (3) the basic optical systems of spectroscopes, spectrometers, and spectrophotometers, (4) the characteristics of wave motion, (5) the…

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 a simple microwave interferometer capable of measuring small phase shifts. Proposes laboratory exercises involving the use of the interferometer in the determination of refractive indices of gases and the analysis of the reflection in a test chamber. (Author/CP)

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)

A demonstration to illustrate sum and difference frequencies of a nonlinear device is explained. (MDR)

Describes the apparatus and procedures for conducting an experiment to measure the relative brightness and degree of polarization of the sky. (SL)
