Discusses changes in ideas about learning underlying reforms in science education. Highlights experiences with project-based science, which focuses on student-designed inquiry organized by investigations to answer driving questions, including collaboration among learners, new technology, and the creation of authentic artifacts that represent…

Describes an approach that challenges students to construct illustrations of chemical reactions by using colorful Bingo card paint markers. Enables them to visually demonstrate their understanding of chemical notations and the law of conservation of mass. Also discusses teaching chemical formulas, a modeling lab, illustrating chemical reactions,…

Describes a Web site for college economics instructors that provides 113 noncomputerized economics experiments (games) to help teach fundamental micro and macroeconomic concepts. Explains that the games are annotated and hyperlinked and that the Web site is organized into three tables classifying the games. (CMK)

Examined contextual factors influencing fourth- to sixth-graders' dislike for aggressors and their victims, by varying aggressor's and victim's behavior in scenarios describing camp experiences. Found that children disliked aggressors the most, followed by victims, and by other children in the scenarios. Aggressors were liked more if their victim…

Develops a simple tree-ring laboratory to demonstrate the basics of dendrochronology. Provides two upper-level laboratory exercises primarily intended to demonstrate the specific dendrochronology subdisciplines of dendroclimatology and dendroecology. Suggests using the exercises separately or in unison as part of a multidisciplinary capstone…

Introduces the plant Amaryllis, which is the common name for the Hippeastrum species. Describes how to grow and bloom Amaryllis in soil using hydroponics. Introduces experiments investigating the anatomy of the bulb, growing and elongation rates, the flower, and foliage. (Contains 21 references.) (YDS)

A room-temperature demonstration of a floating magnet using a high-temperature superconductor is described. The setup and operation of the apparatus are described. The technical details of the effect are discussed. (CW)

Discusses the value of setting-specific research for action research in social psychology. Discusses the following concepts: (1) local variation; (2) seeing the general in the specific; (3) connectedness as the fundamental law of ecology; and (4) the value of field stations for community research. (JS)

Described is a project designed to determine the kinds and types of science laboratories located in and around Yolo County, California. Summarized are some of the sites visited by the investigator and some of the impressions of those facilities. (CW)

High-ability students in grades 3-8 received lessons in organizing a creative investigation and were then compared to control students not receiving the lessons. The most important variables predicting whether the student initiated a creative investigation were membership in the experimental group and pretreatment self-efficacy scores for creative…

Outlines the Cosmic Background Explorer (COBE) mission to measure celestial radiation. Describes the instruments used and experiments involving differential microwave radiometers, and a far infrared absolute spectrophotometer. (YP)

Court rulings have established three basic responsibilities school systems must meet in science programs: (1) inform students about the hazards they might encounter in a science class; (2) provide a safe learning environment and properly maintained equipment; and (3) ensure adequate supervision. Outlines a four-point school safety plan. (MLF)

Examines college students' perception of an interactive videodisc learning system as an alternative to the conventional laboratory for learning biology skills and concepts taught under classroom laboratory conditions. Reports that the videodisc instruction gave more experimental and procedural options and more efficient use of time than the…

Described are three experiments on the photometric, Gaussian, and image-forming properties of a helium-neon gas laser. Details of the experimental method and typical calculations with diagrams and graphs are provided. (YP)
