The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This teaching guide, designed to be read in…

This book is designed to develop sequentially a range of concepts and skills relevant to the basic disciplines of science. Emphasis has been given to the knowledge basis of science, the social context of science, design and technology, and knowledge and skills relevant to personal development. Students are provided an opportunity to engage in…

The Engineering Department's vision for undergraduate education for the next century is to develop a set of laboratory experiences that are thoughtfully sequenced and integrated to promote the full development of students in all courses. Optoelectronics is one of the most important and most demanding courses in Electrical and Computer Engineering.…

The basic elective course in introductory botany is designed for secondary students who probably will not continue study in plant science. The objectives of the course are to help the student 1) identify, compare and differentiate types of plants; 2) identify plant cell structures; 3) distinguish between helpful and harmful plants; 4) predict…

Discusses some difficulties presented by the use of clock reactions with large numbers of students in illustrating the determination of rate laws and the deduction of a mechanism. Suggests the videotaping of a clock reaction without narration to be used with students in stages so that observations can be recorded. (TW)

Describes a laboratory activity that is adaptable to several levels of biology students. Discusses methods for obtaining hellgrammites, performing the experiment, and analyzing the data. Includes sample charts and graphs. (CW)

Describes a crystallography experiment using both diffraction-angle and diffraction-intensity information to determine the lattice constant and a lattice independent molecular parameter, while still employing standard X-ray powder diffraction techniques. Details the method, experimental details, and analysis for this activity. (CW)

Outlines an adaptive framework for the study of plants and their pollinators in which both partners in the ecological relationship are seen as maximizing fitness through efficient use of the other as a resource. Suggests experimental projects to examine the validity of these assumptions giving an evolutionary emphasis. (Author/CW)

Describes the Tardigrada as a group of animals suitable for close study in project work. Gives reasons for their suitability and an illustrated identification key. Discusses possible investigations into the ecology and physiology of tardigrades. (Author/CW)

Discusses the need for student experiments involving the complete characterization of "unknown" inorganic compounds. Describes a project employing a complex metal compound. The compound contains six different components in both inert and labile complexions. Outlines the complete procedure and the preparation of the unknown compound. (TW)

Discusses some of the ways that a cabbage can be used to produce a universal indicator of pH. Describes the methods for producing the indicator, experiments students can do on ordinary household chemicals, and a student take-home assignment for producing pH indicators. (TW)

Describes a lesson designed to help young students conceptualize cholesterol and its effects on the body. Provides young students with a concrete way to understand how cholesterol builds up in blood vessels and restricts blood flow. Includes a simple illustrative experiment for children to perform themselves. (CW)

Describes the concept of a unified laboratory program in which integrated experiments are brought together from several areas of chemistry. Discusses the design and implementation of the unified laboratory at Willamette University, including lists of laboratory experiments and projects. (TW)

Provides three descriptions of demonstrations used in various chemistry courses. Includes the use of a simple demonstration model to illustrate principles of chromatography, techniques for using balloons to teach about the behavior of gases, and the use of small concentrations of synthetic polyelectrolytes to induce the flocculation hydrophobic…

Describes an experiment in which stretching a rubber band can be used to compare the statistical theory of rubber elasticity with its continuum mechanics counterpart. Employs the use of the equation of the state of rubber elasticity and the Mooney-Rivlin equation. (TW)
