Highlights the unanswered questions of science. Summarizes current leading research that demonstrates that those questions are inherently limited in scope, and the chain of discovery and human curiosity that drives the quest for knowledge shows not the slightest sign of ending. Argues that we have yet to recognize and ask many of the most profound…

Describes a scavenger hunt activity that has been used successfully with middle school students in an earth science course. This activity includes items that call for library research rather than the collection of objects, emphasize real-world connections, are skill-oriented, ask for originality and creativity, and are just for fun. (JRH)

Investigates what questions elementary students would ask when presented with various situations relating to the natural environment. Findings reveal the extraordinary range of questions that elementary students have concerning the solar system and space. (JRH)

Uses analogies with everyday objects and materials as a teaching method. Explains geologic time using a roll of toilet paper that has been previously marked with Earth's history. (YDS)

Explores the interrelationship between students' problem-solving ability and their science-process skills in earth science. Statistical analyses indicated that a significantly moderate correlation existed between students' problem-solving ability and their science process skills. Results of a t-test also revealed that there were significant mean…

Reports on the design of a multi-week cooperative learning activity for an undergraduate introductory volcanology class which culminates in the simulation of a volcanic monitoring crisis. Suggests that this activity creates an effective and exciting learning environment in which students have the opportunity to apply theoretical concepts to a more…

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)

Described is a project in which an unmanned aircraft, called Perseus, is used to sample and investigate the atmosphere of the earth. The history of the project, costs, and planned investigations are discussed. (CW)

A high school senior describes her adventures as part of an eight-week glacier expedition in Alaska and British Columbia. Also includes information on how to obtain unique summer enrichment opportunities for teachers and students. (ZWH)

Features a three-part activity designed to teach students about coastal upwelling, the upward movement of cooler, more nutrient-rich water along a coast. Activity includes a mapping exercise, a graphing exercise, and questions for analyzing the map and graph. (Author/WRM)

Presents an activity that enables students to change time into distance to see the "length" of the age of the Earth. (WRM)

Indicates the importance of the development of students' measurement and estimation skills. Analyzes earthquake data recorded at seismograph stations and explains how to read and modify the graphs. Presents an activity for student evaluation. (YDS)

Finds that computer simulations can be used to visualize the processes involved with lunar tides. Technology adds value, thus opening new paths for a more distinct analysis and increased learning results. (Author/CCM)

Shares a 7th grade science teacher's experiences as part of a pilot Earthwatch-Conservation International team assigned to Pantanal, Brazil, and how she utilizes what she learned in her teaching. (ASK)

Describes an activity that uses a simulation of glacial movement to stimulate middle school students' interest in geology. (JRH)
