Describes how the use of a videotape to record the history of a soap bubble allows a study of many interesting events in considerable detail including interference fringes, convection and turbulence patterns on the surface, formation of black film, and the ultimate explosion of the bubble. (JRH)

Presents a segment of the Geoscience Education booklet, Climate Change, that contains information and activities that enable students to gain a better appreciation of the possible effects human activity has on the Earth's climate. Describes the Terrace Temperatures activity that leads students through an investigation using foraminifera data to…

This teacher's guide was developed to accompany the giant-screen film, "Shackleton's Antarctic Adventure". The activities featured use a multidisciplinary approach and target students ages 7 through 14. Teacher pages include background information and student pages include instructions and additional information for understanding the…

Describes a science study tour that included visits to eight European cities. Lists visits to science museums, research centers, and educational institutions. (MLH)

Describes the construction and operation of an apparatus used to study the optical properties of solids using reflection. (JRH)

Describes this year's chemistry exhibition held in Japan and sponsored by the Chemical Society of Japan. Summarizes the purposes, preparation, and the activities of the exhibition. (YP)

Describes a five-step plan of action, formulated by students, to rebuild a pond ecosystem. Steps include cement/rocks, soil/sand, water, producers (autotrophs), and consumers (heterotrophs). (JRH)

Discussed is the physics that underpins Schuster's technique for obtaining a parallel light beam for use in various prism and grating experiments. Basic physics concepts using geometrical optics of prism, together with elementary differential calculus are explained as well as the mechanics of Schuster's technique. (KR)

Suggests a threefold rationale for practical work in science: in developing laboratory skills, in learning to work as a scientist, and in acquiring a feel for phenomena. Three types of pupil practical work (exercises, investigations, and experiences) are then discussed. (Author/JN)

Presents experiments that use the Mattel's Hot Wheels Top Speed toy set to show that work is a measure of energy transferred to or from a system. (JRH)

Discusses some of the problems encountered in teaching electronics in British secondary schools with regard to understanding certain concepts. Describes some ways of teaching the concept of potential in a secondary electronics course. (TW)

Provided are activities and demonstrations which can be used to teach infants about the nature of air, uses of air, and objects that fly in the air. The latter include airships, hot-air balloons, kites, parachutes, airplanes, and Hovercraft. (JN)

Introduced are two experiments: radon detection method shows real data using vacuum cleaner, soft toilet paper, and Geiger-Muller tube; critical potentials measurement describes the operation of Teltron tube with VELA. (YP)

Discussed are the selecting, assessing, and managing of students' investigational works showing how they fit in with the General Certificate of Secondary Education (GCSE) Physics (mature) for London and the East Anglian Group. (YP)

Provided are copy masters, instructions for use, and grading criteria for six problems used as part of the practical assessment for a modular science course. Each problem gives a narrative and a list of materials necessary to complete the problem. (CW)
