This teacher's guide and student text detail the causes and effects of earthquakes and tsunamis. In the teacher's guidebook, suggested activities for each section of the text book's chapters as well as answers to the chapter test problems are presented. Worksheet masters are also provided. Chapters in both books are: (1) "Outside and Inside…

Suggestions are provided for organizing a computer club. Also provided are suggested club activities, including the creation of programs related to science units students are studying. A number of tips are included to help teachers make effective use of club time. (JN)

Project REM (Resources, Energy, Mankind) incorporates energy, ecology, and environmental topics into a sixth-grade science curriculum. Various activities of this year-long project are discussed, including those related to Mr. REM (a student-built "robot") and an all day exploration of energy held near the end of the school year. (JN)

Describes the design, construction, and use of oversize lecture-demonstration atomic/molecular models. These models appeal to both concrete and formal operational students. Also describes construction and use of an "spdf" sandwich board and an experiment using attribute blocks. (JN)

Discusses exercises using a river for the study of river processes and landforms. Although developed for college, they can be adapted for other levels. Exercises involve discharge measurement, flood prediction, and application of the Hjulstrom diagram to river sediments. (JN)

Use of motion pictures and videotape recordings to analyze animal behavior is described. Indicates that accuracy/amount of data available is greatly increased and that simultaneous behaviors of different animals can be studied or individual behavior patterns increased/decreased, providing observers with temporal perceptions similar to the animals…

Describes laboratory activities which encourage students to develop and test hypotheses related to the effects of changing environmental factors on plant growth. Uniform (fair) testing and careful observation and measurement, supplemented by graphing, are emphasized as important in reaching valid conclusions. (JM)

Presents procedures, demonstrations, activities, and teaching suggestions on topics appropriate for middle school science including a simple electrolysis cell, conversion factors, energy, solubilities of salts, condensers, and a worksheet for studying coppice woodlands. (DC)

Suggests discussion questions, demonstrations, and activities related to a Public Broadcasting Service documentary ("To Hear"). The basic theme of the program is that people don't realize the dangers of excessive noise because it is pervasive and invisible. (Author/JN)

A two-part unit for second-grade students was developed to make children aware of the kinds of energy, problems connected with each energy type, and to introduce the decision-making process. Rationale for the unit and individual unit lessons and activities are discussed. (Author/JN)

Discusses determination of elliptical path of a satellite caught into orbit by the sun or earth; using microcomputer as signal generator (includes program listing); collision process; simple hysteresis loop using double beam CRO; method of demonstrating parallelogram of forces; measuring radius of electron beam curvature; and half-life of thorium…

Lasers are useful for demonstrating ray optics, especially in large classrooms where a well-defined, easily-viewed ray is essential. Described is a simple device that converts any laser to a projection oscilloscope (or laser spirograph). Suggestions for using the device (including demonstrating Lissajous figures and conic sections) are provided.…

Describes laboratory procedures, demonstrations, and classroom materials, including "diet poker" (nutrition game); an experiment on enzyme characteristics; demonstrations of yeast anaerobic respiration and color preference in Calliphora larvae; method to extract eugenol from clove oil to show antibiotic properties; and Benedict's test.…

Emphasizes the importance of imagination in scientific discovery and science education and identifies three processes which increase the richness of the visualization experience: relaxing, concentrating, and seeing. Suggests topics for guided experiences and example models for earth/space, life, and physical sciences. (DC)

Summarizes two research studies on: (1) suitability of science reading materials at CSE and O levels, and (2) effects of single sex and coeducation on science subject (N=1200) preferences and choices at 14+. Discusses spider diagrams, what is science, and problems and solutions in chemistry teaching in post-16 institutions. (DS)
