Presents the author's reasons for supporting the CHEMS program. Also characterizes aspects of his teaching regarded as significant in teaching chemistry, including prompt return of assignments, test retakes, videotaping. inclusion of organic chemistry, ability grouping of students, avoidance of specialization, and departmental testing. (CS)

Illustrates various ways to adapt commercially or teacher-prepared teaching aids to accommodate the needs of visually impaired students while retaining usability by sighted students. Focuses on tactile changes involving, for example, cutout figures, raised surfaces, and punched holes. (DC)

Describes an advanced undergraduate physics experiment which permits the measurement of ultrasound velocity and absorption in liquid systems. A description of the tasks the student is expected to perform is also included. (HM)

Describes a laboratory scale reactor that determines the kinetics of a gas-solid catalytic reaction. The external recycle reactor construction is detailed with accompanying diagrams. Experimental details, application of the reactor to CO oxidation kinetics, interphase gradients, and intraphase gradients are discussed. (CS)

Presents four notes that report new equipment and techniques of interest to physics teachers. These notes deal with collosions of atoms in solids, determining the viscosity of a liquid, measuring the speed of sound and demonstrating Doppler effect. (HM)

Presents a brief overview of the important processes and techniques used industrially for forming thin films. (HM)

Provides specific information about the eruption of Mt. St. Helens in March 1980. Also discusses how volcanoes are formed and how they are monitored. Words associated with volcanoes are listed and defined. (CS)

Describes the preparation and use of a film for presenting demonstrations during chemistry lectures. Includes student responses to and costs of these filmed demonstrations. Instructors provide their own documentary since the film lacks a sound track. (JN)

Reports on trends in the reading of popular scientific literature among students in Poland. (MKM)

Discusses concept of covalent bonding as related to homonuclear diatomic molecules. Article draws attention to the existence of bound rare gas and alkaline earth diatomic molecules. Summarizes their molecular parameters and offers spectroscopic data. Strength and variation with distance of interatomic attractive forces is given. (Author/SA)

Included is information regarding: sucrose dehydration by sulphuric acid; an example of school-industry link in studying zinc oxide production; viscous flow in inorganic silicate glass; construction of a peristaltic pump; electrolysis; carbon dioxide preparation; electrophoresis; safety in using hydrogen and sulphuric acid; and approaches to…

Describes the use of transistors instead of valves for Lecher line and radiation demonstrations. Two oscillator circuits which provide power for Lecher line use are described. Impedance of Lecher line is also discussed. (HM)

A comparison was made of different treatment approaches to science material for fourth grade students (color realistic photographs with written text, photographs integrated within written text, and written text without pictures) with previous student achievement (high, medium, and low placement). Also interactive effect between treatments and…

Describes a game format and procedures for developing teacher-prepared games in environmental education. Uses a game board, place markers, dice, and question and problem cards. Discusses development of learner objectives and preparation of evaluation procedures as well as follow-up tasks in revision. (CS)

Sketches the history of children's books about science, from the first picture book in Germany in 1658 to Louis Agassiz's work on establishing science firmly in the education of young people in America. States that science books need to be accurate, and they must demonstrate the "scientific method." Outlines 11 characteristics of science…
