Details the use of tabletop models that demonstrate concepts in direct current electrical resistivity, self-potential, and electromagnetic geophysical models. Explains how data profiles of the models are obtained. (DDR)

Presents an activity in which water temperature is investigated in relation to water depth, weather patterns, land use, time of year, and other factors students choose to investigate with data collected from the Internet. Uses the Great Lakes as the setting for this investigation and examines how and why the temperature of a body of water changes…

Reports on the two most commonly used resources on global climate change available on the Internet and provides examples of classroom activities. (Author/YDS)

Explains how physics teaching can be more relevant for elementary and secondary students by integrating physics and earth science content that students can relate to and understand. Identifies and explains Earth contexts that can be appropriately implemented into the physics curriculum such as waves, magnetism, and electricity. (Author/YDS)

The teaching of physics as an integral part of an undergraduate oceanography course is described. A general outline of oceanography and the corresponding physics topics is given. The objectives, organization, and difficulties of such a course are discussed. (CW)

Methodology which can be used to evaluate cyclic trends in sequential data are discussed. Examples and suggestions for teaching using this method are provided. A list of 25 references is included. (CW)

The design and data management of an activity to study weathering by increasing the rate of mineral dissolution in a microwave oven is described. Data analysis in terms of parabolic and first-order kinetics is discussed. (CW)

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

A teaching method in which students develop models of simple systems to learn critical thinking and scientific methodology is presented. Discussed are the stages of the development of a model and the possible outcomes of the use of model development for students. (CW)

Described is an astronomy lesson designed to explore the relationship between the angle of the sun, the position of the north star, and the horizon line of a local area. Activities for teaching protractor fundamentals are included. (CW)

Explains how studying a floodplain can help students analyze the interactions between humans and the physical environment. Analyzes data from two cities in California to demonstrate that housing prices did not rebound after a flood. (GG)

Investigated was the mathematical content of 15 college-level physical-geology textbooks published in the period 1980-90. A list of textbooks is provided. Methods, comparisons with other fields of science, and the treatment of specific geological concepts are discussed. (CW)

Examines anxiety levels about teaching and achievement before and after an earth science course. The State-Trait Anxiety Inventory was used to measure anxiety. Reports that initial anxiety levels were changed in a positive direction and significant gains were made in achievement of concepts. (YP)

Describes the change of earth's magnetic field at the boundary between the outer core and the mantle. Measurement techniques used during the last 300 years are considered. Discusses the theories and research for explaining the field change. (YP)

Discussed are methods which can be used to stimulate creative thinking in geology students by focusing on what is not known about sandstone petrology. The impact of recent advances on graduate geology teaching are highlighted. (CW)
