Describes a simplified redox method for total iron analysis suitable for execution in a three-hour laboratory period by general chemistry students. Discusses materials, procedures, analyses, and student performance. (CW)

Describes how to construct a simple device that students can use to estimate how high their kites are flying, as well as the heights of other objects. (TW)

Contains 10 teaching tips about such topics/ideas as low-impact nature trails, sand, overhead transparency use, the cause of "trash," rainbows, the solar system, controlling variables, time keeping, science discovery centers, and animal characteristics. (TW)

Describes some art activities for early childhood that also teach about science. Expresses concern that young children operating in a three-dimensional world are often expected to translate their world onto a flat sheet of paper. (TW)

Discusses some of the variables involved in the development of five environmental education days by the Delaware Valley (Pennsylvania) Middle School. Recounts some of the ways that support was generated for programs from school administrators and community resources people. (TW)

Discusses the conventional approaches to teaching about chemical equilibrium in advanced physical chemistry courses. Presents an alternative approach to the treatment of this concept by using Boltzmann's distribution law. Lists five advantages to using this method as compared with the other approaches. (TW)

Describes how a learning strategies approach can enable learning disabled students in secondary schools to study effectively, using as an example the acquisition of specific information from reading a chapter in a science text. (JC)

Describes a polymerization reactor engineering course offered at Michigan Technological University which focuses on the design and operation of industrial polymerization reactors to achieve a desired degree of polymerization and molecular weight distribution. Provides a list of the course topics and assigned readings. (TW)

Notes some of the conflicts between the use of hands-on science curricula and standardized testing. Discusses the state of testing and the state of science education with regard to the tests. Describes some promising developments in assessment in science education. (TW)

Describes a classroom experiment designed to teach students the fundamentals underlying the normal coordinate analysis procedure of a polyatomic molecule. Uses a reverse procedure from traditional experiments of this type by providing the values for the force field and working backwards. (TW)

Reports on a study designed to determine the importance of images to experienced chemists and the nature of images among learners, with particular attention to correlations with level of learning. Suggests that instructional methods should consider the student's ability to develop specific images appropriate to the chemical concepts. (TW)

Describes some of the characteristics of various reptiles. Contains teaching activities including making reptile number books and identification keys, flip-ups about cobras, puzzles involving graphing, and group presentations. Includes reproducible handouts to be used with some of the activities. (TW)

Addresses the call for university undergraduate physics programs in Great Britain to be more concerned with the relationship between physics and the outside world, particularly with business and industry. Describes some of the constraints on this movement, as well as some of the strategies currently being used to overcome the obstacles. (TW)

Reports on a study in which two spatial tests were given to science and engineering majors and to students in nursing and agriculture at Purdue University (Indiana). Scores from the tests consistently contributed a small but significant amount of success on measures of performance in chemistry. (TW)

Abstracts of seven selected papers from the 7th Annual Microcomputers in Education Conference are presented. Papers are included on microcomputer-based labs, teaching science with robots, microcomputer software, problem solving, computer integrated math activities, and computer assisted mathematics. (RH)
