While interdisciplinary collaboration is desired among researchers, traditional science instruction generally results in science disciplines being taught as separate entities. This study focuses on student understanding of concepts at the intersection of two isolated disciplines--geoscience and bioscience--across two purposeful samples of…

Students learn science best with activities that mirror the way scientists work. This article describes how geologists investigate groundwater flow systems in areas of karst topography--geologic formations shaped by dissolving bedrock--and provides a way for students to replicate this research. Students also use electric current to model water…

Describes scientific research on an Earthwatch expedition to study Arenal, one of the world's most active volcanoes, in north central Costa Rica. The purpose of the two-week project was to monitor and understand the past and ongoing development of a small, geologically young, highly active stratovolcano in a tropical, high-rainfall environment.…

Provides a "template" for how a stream ecosystem functions. Discusses the physical and chemical factors of geology, light, current velocity, temperature, and energy sources. Describes functional groups of aquatic insects and the River Continuum Concept, a model of interaction that explains the spatial occurrence of aquatic insects. (LZ)

Demonstrates the magnitude of an extinction event by using a simulation to illustrate the massive nature of the loss of a family and the number of species that perish to achieve that result. (RT)

Provides a format for the identification of fossils when introducing geologic time in the laboratory. Presents an organization of fossils into three major groups based on radial, bilateral, and no apparent symmetry. States that this method reinforces student learning and provides for an orderly approach to fossils. (RT)

Recounts the adventures of a journey taken through France and Italy. Makes an analogy of this trip to that of the one Charles Dickens took in 1844. Describes silicified horizons of the southern Paris Basin, moraines, outcrops, and "Hoodoos." (RT)

The history of the sciences in America in 1880 is described as a time of considerable vitality in the disciplines of earth and life sciences. The natural scientific resources of the American continent are credited as contributing to the vitality. Pluralism of institutional support is discussed with a historical perspective. (SA)

Discusses MAX, an interactive computer program for teaching identification of clay minerals based on standard x-ray diffraction characteristics. The program provides tutorial-type exercises for identification of 16 clay standards, self-evaluation exercises, diffractograms of 28 soil clay minerals, and identification of nonclay minerals. (MDH)

Presents reviews by classroom teachers of software for teaching science. Includes material on the work of geologists, genetics, earth science, classification of living things, astronomy, endangered species, skeleton, drugs, and heartbeat. Provides information on availability and equipment needed. (RT)

Computer software, audiovisuals, and books are reviewed. Includes topics on interfacing, ionic equilibrium, space, the classification system, Acquired Immune Disease Syndrome, evolution, human body processes, energy, pesticides, teaching school, cells, and geological aspects. Availability, price, and a description of each are provided. (RT)

Describes "Einstein's Adventurarium," a science center housed in an empty shopping mall in Gillette, Wyoming, created through school, business, and city-county government partnership. Describes how interactive exhibits allow exploration of life sciences, physics, and paleontology. (KDFB)
