Discusses ways in which teachers can improvise with common household objects and thus avoid the expense of purchasing new science materials. (JR)

Discusses the Peltier, or thermoelectric effect, which provides a way of cooling a system by coupling it thermally to the junction of two materials suitably chosen, shaped, and connected to a d.c. current. Describes an apparatus which simply and inexpensively demonstrates this effect. (MLH)

Describes the results of a report based on a questionnaire and survey conducted on the problems associated with the supply of essential biological materials to secondary schools and suggestions as to how they might be solved. (BR)

Describes an apparatus that provides continuous flame colorization for the study of the emission spectra of metals. (GS)

Presented is a descriptive account of Alessandro Volta's first notable success in 1775, the invention of a unique method of generating electricity. Luigi Galvani's announcement of his theory of "animal electricity" in 1972 is integrated into this interpretation of Volta's discoveries with electricity. Five experiments are described: (1)…

SURVEYS WERE CONDUCTED TO DETERMINE THE AVAILABILITY OF HIGH SCHOOL SCIENCE FACILITIES AND EQUIPMENT IN SEVEN STATES. THIS WAS ACCOMPLISHED THROUGH PERSONAL INSPECTIONS BY A PROJECT COMMITTEE, USING CHECKLISTS OF APPROXIMATELY 850 SCHOOLS SELECTED AT RANDOM. AN ANALYSIS OF THE DATA WAS THEN MADE, AND SOME GENERAL IMPLICATIONS WERE SUGGESTED.…

THE DEVELOPMENT OF A NEW AND MORE ACCEPTABLE SCHEME OF TEACHING ELECTRICITY IS THE OBJECTIVE OF THE PHYSICS PANEL OF THE EDUCATION COMMITTEE OF THE ASSOCIATION FOR SCIENCE EDUCATION. IN CONTRAST TO THE "PARALLEL FIELD" APPROACH OF AN EARLIER PUBLICATION IN 1954, THE APPROACH IN THIS BOOK IS BASED ON RADIAL FIELDS, POINT CHARGES IN…

Discussed are two studies undertaken by the Commission: The Cost of Material Study and The Science-Mathematics S"udy. Early plans in The Cost of Material Study were to specifically tabulate costs of introducing and maintaining each of eight "new" science courses in elementary and junior high schools. This was abandoned in favor of…

This guide was prepared as an aid to teachers of general science 1-2, grade 8. One of the major purposes of the guide is to assist the teachers in adopting a discovery-oriented approach in the classroom. The course is designed to prepare able students for the advanced science courses, grades 9-12. Teaching techniques, homework, laboratory…

Studied were (1) the evolving use of the microscope in science education, and (2) its relationship to the changing teaching methods, content, and emphases of science courses and to the prevailing philosophies of education of nineteenth century American colleges. To establish the necessary background, the evolution and availability of the…

A discussion is presented of the importance of science in the school program, the objectives of science teaching, and facilities for science instruction. Descriptions are then presented regarding the size and facilities necessary for the general science room, the darkroom, the biology room, the physics room, and the chemistry room. Two diagrams…
