Designed to address the major conceptual problems associated with light and vision, appearances of surfaces, and color, this module can be used with high school students or college nonscience majors including those in elementary education. It is one in a series developed by the project "Overcoming Critical Barriers to Learning in Nonmajors'…

This life science activity module was designed to facilitate student conceptualization of plant growth. It is intended for use primarily in elementary grades but may be useful at higher grades. It provides students with hands-on experience and observational skill development. The package provides: (1) a teacher background sheet; (2) an activity…

Describes a two-quarter chemistry course designed to enable civil engineers to perform water analysis studies. (PB)

Describes the functioning of temperature transducers, or thermistors. Discusses the interface connections between thermistors and the game-port of several kinds of microcomputers. Demonstrates how to construct a thermistor probe and suggests several applications of the use of such probes in various scientific experiments. (TW)

Provides some background information on acid deposition. Includes a historical perspective, describes some effects of acid precipitation, and discusses acid rain in the United Kingdom. Contains several experiments that deal with the effects of acid rain on water quality and soil. (TW)

Contains 21 articles ranging from instructional experiments to topical information. Deals with investigation of plant rust diseases, using computers to teach biology, plant roots, a biotechnology curriculum, the corrosion of oxides, electrochemical simulations, the Reimer-Tiemann reaction, the oxidation of aldehydes, and the extraction of iodine…

Reports on a study which compared the effectiveness of microcomputer simulated experiences with that of parallel, hands-on laboratory instruction for teaching the concept of volume displacement to junior high school students. Results indicated that computer simulated experience were as affective as hands-on laboratory experiences. (TW)

Describes an inservice teacher workshop conducted in Pennsylvania which was designed to encourage the introduction of chemistry at the elementary school level. Discusses the organization and content of the workshop, the materials used, and some evaluative information provided by workshop leaders, teachers, and their students. (TW)

Describes the use of a precalibrated stainless steel thermistor, interfaced with an Apple computer, in chemistry experiments. Discusses the advantages of "instant" temperature readings in experiments requiring that readings be taken at certain intervals. Outlines such an experiment which investigates freezing point depressions. (TW)

Discusses the use of two different computer applications to teaching college chemistry. Describes the "electric laboratory notebook" (ELN) courseware and its use in an instrumental analysis course. Provides an overview of the use of commercial spreadsheet programs in the chemistry laboratory. (TW)

Discusses some of the advantages of using overhead projectors to demonstrate chemistry experiments. Provides a list of guidelines and equipment for these types of demonstrations. Describes 21 simple demonstrations that can be done in chemistry classrooms that require minimal equipment and cost. (TW)

Details 26 experiments designed for use in secondary or college science classes. Includes activities for physical and biological sciences. Describes procedures, materials, safety, and analyses appropriate for each. (CW)
