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…

The purpose of this study was to understand how Thai scientists from four disciplines viewed nature of science (NOS). The sixteen participating scientists were chosen from the areas of chemistry, physics, biology/life sciences, and geology/earth sciences and were separated into novice and expert groups. The scientists' understandings about NOS…

Describes information learned about Mars from past Mariner probes. Discusses future space probes that are expected. (RH)

Discusses discoveries made during 1976 in various areas of invertebrate paleontology. (MLH)

Describes discoveries made in 1976 in areas of vertebrate paleontology, including research indicating that dinosaurs were warm-blooded. (MLH)

A brief summary of work completed by micropaleontologists in 1978. (BB)

Contributions to this field for 1978 are discussed. Of special interest are the jawless marine fishes that were found in marine deposits from Late Cambrian time. (BB)

Research efforts tended to focus on the ancestry of major groups in 1978, and in particular on Cambrian fossils. (Author/BB)

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)

This guide offers a systematic approach to the wide variety of published biographical information on men and women of science in the life, earth and physical sciences, primarily from 1989 to 2006, and complements Library of Congress Science Tracer Bullet "TB88-3" ("Biographical Sources in the Sciences," compiled 1988 [ED306074]) and "TB06-7"…

Information concerning the eight science college commissions now in existence is provided. These commissions encompass the fields of agriculture, biology, chemistry, engineering, geography, geology, mathematics and physics. An overview of the primary functions and commitments of the commissions and consulting services offered is presented. Also…

A brief summary of the year's activity. (BB)
