Presents lessons to stimulate children's interest in science and develop communication skills by having students simulate the locomotion of an ameba, a paramecium, and an Euglena, and the cyclosis in the pondweed Elodea. Students practice communication skills by demonstrating their organism to the remainder of the class. (MDH)

Describes the use of observation folders as a tool for understanding and refining the basic skills of observation and inference that are important to the young child. These folders provide opportunities for students to view and examine "mystery pictures," make inferences, and arrive at their own conclusions about the subject of the…

Provides a summary of atmospheric science resources available to help science teachers develop up-to-date units on weather. Resources include activities of professional organizations involving radio, television, printed materials, inservice workshops, and telecommunications resources. (MDH)

Finds sustained benefits to teachers two years after a summer hands-on science workshop for middle grades teachers. Discusses key elements responsible for the workshop's sustained success. (SR)

Special science and mathematics programs available to students at the Weizmann Institute of Science in Israel are described. The Summer Science Institute, mentor programs, screening procedures, science clubs, an outdoor interactive science museum, science fairs, mathematics olympia, a "mathematics by mail" program, and the International…

Described is a LOGO computer program that enables students to investigate the relationship between a digital number and the resistance in a variable resistor used to generate that number. Likewise, actual temperature readings and the corresponding resistance within a thermistor can be used for data gathering and subsequent analysis. (JJK)

Described is a summer workshop for college and high school educators designed to raise the level of expertise of the participants and to raise their awareness of physiology and medical opportunities for their students. The objectives, organization, schedule, content, credit, financial considerations, and evaluation of the program are discussed.…

This article takes a critical look at practical work in school science and the often extravagant claims that are made for it. A case is made for a more rigorous, theory-driven approach to practical methods. (Author/CW)

A simple experimental arrangement that makes it possible to simultaneously observe and compare on a screen the two interference patterns produced by reflected and transmitted light from incident white light impinging on a soap film directly is described. Procedures and illustrated effects are discussed. (CW)

Two experiments which can be used to illustrate light diffraction using compact disks are detailed. Included are procedures, computations, and probable results. (CW)

Ten demonstrations of a variety of physics concepts are presented. Included are procedures and explanations of the effects illustrated. (CW)

Described are projects of the National Sciences Resource Center (NSRC) which are aimed at the improvement of elementary school science instruction. Plans and goals of the project are listed. The Science and Technology for Children project is highlighted. (CW)

To make elementary science students grasp the scientific concepts being taught, teachers must not ignore their preconceived ideas. Instead, teachers must identify misconceptions then help the students test them. The article presents a step-by-step approach that can serve as a model for teaching any science concept. (SM)

Describes using the course question: "How does chemistry (or biology) impact my personal life and society?" This course question is presented to students and forms the basis of the final exam. Students evaluate a current-events article using the question as a framework. Students explore the relationship between chemistry (or biology) and their…

Describes the use of practice weighings and handling of fluorescent compounds to assist in teaching students safe-handling techniques. (PR)
