Provides three exercises that introduce high school and college students to a common strain of the tobacco mosaic virus and the study of some basic biological processes. Activities involve inoculation of plants and observing and recording symptom development in infected plants. (DDR)

Presents an activity in which students are assigned occupations that rely on specific minerals. To obtain the needed minerals, students learn how to trade services and commodities. Includes details on preparation, modeling behaviors, and printed materials. (DDR)

Evaluates the participation of high school students in the activities of an international conference on experimental biology. Students develop criteria to overcome difficulties with vocabulary and content and acquire updated scientific information. (Author/DDR)

Describes the use of several teaching techniques based on constructivist educational theory. The teaching techniques are used with preservice teachers to enable them to experience active learning strategies in the context in which science is practiced. (Contains 19 references.) (DDR)

Details an ocean-based lesson and provides background information on the designation of 1998 as the "Year of the Ocean" by the United Nations. Contains activities on the poster insert that can help raise student awareness of coastal-zone hazards. (DDR)

Briefly summarizes methods of presenting laboratory information. Suggests that approaching lab problems requires a combination of methods structured into a problem-oriented learning experience. Focuses on the relationship of the gloxysome to the chloroplast and the steps involved in solving the problem. (DDR)

Describes the use of Calculator-Based Laboratory (CBL) technology and a projectable TI-83 graphing calculator to demonstrate the kinetic behavior of a complex reaction. Explains how the CBL is used to review first-order reactions and the graphing calculator is used to determine the rate constants for a series of consecutive first-order reactions.…

Describes general curriculum design principles and specific software design implementations resulting from an ongoing collaboration between software designers and programmers, researchers, and a classroom teacher and his students. Traces the development of E-Lab software in the context of the principles that emerged during the design process.…

Discusses preliminary research on a new heuristic tool for learning from laboratory activities in secondary science. Finds that use of the science writing heuristic facilitated students in generating meaning from data; making connections among procedures, data, evidence, and claims; and engaging in metacognition. (Contains 29 references.)…

Describes the benefits of using calculator-based laboratory equipment in science classes. (WRM)

Summarizes ideas for new demonstrations, experiments, and science-in-society topics for teaching chemistry. (WRM)

Describes the use of case studies for teaching introductory anatomy and physiology courses. Outlines methods for constructing cases from news stories. Includes an appendix featuring a sample case story. (Contains 11 references.) (WRM)

Illustrates the use of a module used in Mexican schools that focuses on survival on a deserted island. Explores questions related to inhabitants of the island, predator-prey relationships, identification of natural resources, water and food issues, and health considerations. (DDR)

Presents sand and water activities for young children as examples of sensory explorations, science activities, and comforting play. Includes information on health and safety precautions, adaptations for children with physical disabilities, the use of other materials, and sand and water toys made from one-liter plastic bottles.

This article examines variations in patterns in the enactment of a large-scale kindergarten through Grade 12 science inquiry program. Student data reports in the GLOBE program provide a useful measure of implementation because key design elements in the program are student collection and reporting of local environmental data. We examined…
