Based on instructional experiences at Charles County Community College, Maryland, this report examines the pedagogical advantage of teaching atomic absorption (AA) spectroscopy with an AA spectrophotometer that is equipped with a microprocessor and video output mechanism. The report first discusses the growing importance of AA spectroscopy in…

Instructions accompanied by illustrations for building a low-cost demonstration spectroscope are presented. Materials and tools are pictured and labeled. Cost is estimated at five dollars (in 1980) and twelve hours of work are required to build the spectroscope. (SA)

A NEW EMPHASIS ON SCIENCE IN THE ELEMENTARY SCHOOL HAS STIMULATED SUPERVISORS, ADMINISTRATORS AND MANY TEACHERS TO SEEK INFORMATION ON SOURCES, SELECTION, AND USE OF APPROPRIATE MATERIALS AND EQUIPMENT IN INSTRUCTION. THIS BULLETIN IS MAINLY TO HELP THE NEOPHYTE WHO IS INTERESTED IN THE BASICS OF ELEMENTARY SCIENCE TEACHING. THE DISCUSSION IS…

THE PURPOSE OF THIS STUDY WAS (1) TO DETERMINE THE READING DIFFICULTY OF THE EIGHTH-GRADE SCIENCE TEXTBOOKS ADOPTED FOR USE IN TEXAS PUBLIC SCHOOLS AND (2) TO DETERMINE THE ADEQUACY OF TEACHER PREPARATION, EQUIPMENT, AND SCHOOL FACILITIES FOR PRESENTING A COURSE IN EARTH SCIENCE BASED UPON THE TEXTBOOKS ADOPTED IN 1964. DATA FOR THE READABILITY…

PROCEDURES FOR IMPROVISING LABORATORY EQUIPMENT FOR AN ACTIVE ELEMENTARY SCIENCE PROGRAM AND SOME SUGGESTED APPLICATIONS ARE PRESENTED. NEW COURSES OFTEN REQUIRE APPARATUS KITS AS WELL AS TEACHER'S GUIDES IN ORDER FOR THE PROGRAM TO BE CARRIED OUT AS DESIGNED. AS SCIENCE PROGRAMS EXPAND, MORE VERSATILITY, FLEXIBILITY, AND BROADER APPLICATION ARE…

Presented are abstracts of 700 computer programs in marine science. The programs listed are categorized under a wide range of headings which include physical oceanography, chemistry, coastal and estuarine processes, biology, pollution, air-sea interaction and heat budget, navigation and charting, curve fitting, and applied mathematics. The…

Twenty-four teachers, from a school system not using the new elementary science programs, taught representative new units to 544 students, with variations in their inservice training and the amount of classroom science equipment provided. Classrooms at three grade levels (1, 3, and 6) were used twice under opposing conditions. For each unit, the…

Indexed are articles relating to oceanography and limnology published in "The Science Teacher" between 1960 and 1969. Articles are indexed under title, author, and topic. Topics include background information, course descriptions, and laboratory equipment and techniques. (EB)

This document describes the theory and mode of operation to be used with a cathode ray oscilloscope. Safety percautions to be taken, methods of calibration, and uses of the equipment in school operation are given. A brief "trouble-shooting" section and a bibliography of other reference is included. (GR)

The system for determining parameters of a particle described in this document is a government-owned invention that is available for licensing. The background of the invention is outlined, and drawings of the system together with a detailed description of its function are provided. A collector contains a hole and annular apertures for transmitting…

Provides a method for determining the orientation of the polar axis of an equatorially mounted optical telescope. The background theory illustrates some important properties of the celestial sphere and gives an insight into the usual "rule of thumb" methods of axis orientation; it also provides a basis for instructors and students to…

Several teaching aids including a microcomputer system, a process control laboratory, a mechanics laboratory, and a teaching polariscope are described. (RH)

Beverage cans are well suited for sediment collection and storage containers. Advantages include being free, readily available, and the correct size for many samples. Instruction for selection, preparation, and use of cans in sediment collection and storage is provided. (RE)

Presents information about equipment and new products such as the melting point instrument and TV-microscope coupler which are helpful in college science teaching. Descriptions of each product, how it operates, its prices, and address for ordering are presented. (HM)
