Presents the procedures, results, and conclusions of a study designed to examine the efficacy of visual advance organizers for learning earth science concepts. (LC)

Perceptual orientation (field dependence/independence) was related to 47 biology/earth science students' attitudes toward science. In addition, students who were field dependent and possessed a positive attitude scored significantly higher on a science achievement test than students who were field dependent and possessed a negative attitude. (JN)

Describes two- and three-year undergraduate curricula for training earth science technicians at Sir Sanford Fleming College (Canada), emphasizing practical aspects and close student-faculty interaction. List of employment opportunities for geology graduates based on past placement data and geology curriculum outline are provided in tables. (JN)

The earth's oceanic crust is created and destroyed in a flow outward from midocean ridges to subduction zones, where it plunges back into the mantle. The nature and dynamics of the crust, instrumentation used in investigations of this earth feature, and research efforts/findings are discussed. (JN)

Discusses the earth's biosphere, considering how the microbial, animal and plant life (which make up the biosphere) are sustained by the earth's lithosphere, hydrosphere, and atmosphere. Also considers how these three earth features have powerfully shaped the evolution of these organisms. (JN)

Materials needed and instructions for constructing a model (groundwater terrarium) to examine the water cycle and its effects are provided. Suggested activities and demonstrations are also provided. (SK)

Highlights current information on the martian surface. Topics include a planetary overview (atmosphere, dust storms, water vapor/ice, soil analysis) and surface features (craters, volcanoes, canyons/channels, polar regions, wind-related features). Similarities/differences between Mars and Earth are also discussed. (JN)

In addition to oceans, the earth is subjected to tidal stresses and undergoes tidal deformations. Discusses origin of tides, tidal stresses, and methods of determining tidal deformations (including gravity, tilt, and strain meters). (JN)

Facts about the geological formation and modern functions of Niagara Falls are given in this article, the second in a series about natural wonders. Questions for class discussion, directions for making a model waterfall, possible writing topics, and resources for further information about waterfalls are included. (PP)

Summarizes 1981-82 enrollment data on geoscience students from 460 United States and Canadian degree-granting college and university departments. Includes enrollment data for males and females, minorities, and geology students. Also includes numbers of bachelors, masters, and doctoral degrees received. (JN)

Describes an inexpensive (about $1,500) direct-readout ground station for use in secondary school science/mathematics programs. Includes suggested activities including, among others, developing map overlays, operating station equipment, interpreting satellite data, developing weather forecasts, and using microcomputers for data storage, orbit…

Describes a simulation drilling core activity involving the use of a physical model from which students gather data and solve a three-point problem to determine the strike and dip of a buried stratum. Includes descriptions of model making, data plots, and additional problems involving strike and dip. (DS)

The success of an outreach education program held by Indiana University-Purdue University at Indianapolis is described. The college offers regular credit courses on Saturday and Sunday for people who could not take regularly scheduled courses. A Learn and Shop program held at shopping centers is also described. (JT)
