Recommendations are given for obtaining high quality preparations of chromosomes with relatively little equipment using an improved Feulgen-squash technique. (Authors/SA)

Presents a method for microscopically examining cytoplasmic streaming in root cells, and physiologically examining the delivery of ions to the xylem exudate. The expected result does not occur and the authors believe that students learn to re-examine the assumptions, thereby increasing their skills in scientific inquiry. (Authors/SA)

Presented is a variety of tips for parents and teachers for exploring the outdoors with children. Activities are grouped according to appropriateness to the four seasons. Ideas presented relate to role playing, games, group problems, values, pollution, arts and crafts, science, record keeping, music, and classroom nature. (SA)

Described in this article is an energy conservation simulation game in which students participate in a space mission to Mars. Activities such as decision making, valuing, and problem solving occur during the game. (SA)

Activities are suggested for children following a neighborhood walk in search of autumn's nature collectibles. Simple and complex studies are suggested. (Author/SA)

This discussion of science teaching in general includes several specific examples of activities designed to be adapted to different grade levels or types of students. (MK)

Presents suggestions for helping children gain in spatial abilities. Activities are given which require that students use spatial concepts in order for them to be successful. (Author/SA)

Presents a general step-by-step description of how classroom games for science can be developed. Examples from the slim chance game from the Health Activities Project of the University of California at Berkeley are included. (HM)

Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

Discusses how laboratory activities can match science teaching goals. Analysis of two commonly used laboratory investigations in high school physics and biology are presented using a list of 24 skills and behaviors which are related to the processes of scientific inquiry and problem solving. (HM)

Provides rich description of the biological diversity found in a 30-mile section of Nebraska known as the "biological crossroads." Argues that the seven major associations of the Niobrara River valley provide a great classroom. Includes a complete listing of plant species. (DDR)

Presents a series of laboratory exercises designed to introduce students to a realistic experience in biological research that is feasible with large numbers of beginning biology majors. The exercises center on the study of alkaline phosphatase. (DDR)

Defines approaches to inquiry-based science teaching and describes many ways in which to conduct this kind of science instruction. Argues that with science reform underway, opportunities exist to transform classrooms into environments with active learners engaged in inquiry. (DDR)

Presents an activity and background information to help students in America's Midwest understand that the world is in the midst of a global food crisis. Discusses the view that hunger is a daily concern with serious social, political, and economic consequences. (DDR)

Describes the West Michigan Science Festival which features a variety of interactive events in manufacturing, electronics, health care, engineering, and other fields. Brings together students, businesses, industries, and educators in a community celebration of science, mathematics, and technology. Discusses beginnings, business partners, events,…
