This 30-page PDF was prepared by the Alaska Department of Natural Resources and provides detailed information about the water supply available on St. Paul Islands. The site presents the results of an aquifer test and estimates potential yield from current wells. Tables, diagrams and well logs are included.

In this activity, students explore how different sediment properties influence slope stability. They make piles of sediments with varied grain size, angularity, and water content and measure the maximum slope at which the grains are stable. The results are then used to examine the nature, frequency, timing, and causes of landslide events in Seattle. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

Information includes news stories, scientific analysis and background, eyewitness accounts, photo galleries, pressing questions, hurricane animations and more. Information has been updated frequently.

This exercise is designed to help students get their brains around big numbers using real world examples. The real-world examples are focused around money issues such as the national debt and budgeting. There are questions for students and some guidelines. These exercises are one of several that were produced for the National Numeracy Network under a grant from the Woodrow Wilson Fellowship Foundation through the National Council on Education and the Disciplines. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

This site contains materials to help teach a Chance course, an NSF-sponsored quantitative literacy course that was cooperatively developed by the Chance Team. The goal of Chance is to make students more informed, critical readers of current news stories that use probability and statistics. Links to Chance news, the course, video and audio, teaching aids, and related resources are provided.

This resource describes the Columbia River Basalt Group. The site features brief discussions of the stratigraphy and age of the group, as well as the group's vent system, volumes and eruption rates, and magma supply rates. This CRBG description is an excerpt from the ICG Field Trip T106: Cenozoic Volcanism in the Cascade Range and Columbia Plateau, Southern Washington and Northernmost Oregon: American Geophysical Union Field Trip Guidebook T106, p.21-24.

This report features procedures for implementing cooperative learning in courses that stress quantitative problem solving. The objectives of the report are to offer ideas for using cooperative learning effectively in technical courses, to give advance warning of the problems that might arise when CL is implemented, and to provide assurances that the eventual benefits to both instructors and students justify the perseverance required to confront and overcome the problems encountered.

In this activity, students explore Daisyworld, a model of a self-regulating system incorporating positive and negative feedbacks. The model explores the effect of a steadily increasing solar luminosity on daisy populations and the resulting planetary temperature. The activity was developed to introduce upper level undergraduate students to the concepts of dynamical systems modeling. The exercise guides students through some of the mathematics behind the modeling. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

This web site provides a pro-environment position on geothermal energy development. The site offers environmental principles that should be adhered to, and points out the environmental benefits of geothermal energy. There is also a useful discussion of geothermal energy, where geothermal resources are located, the current state of geothermal development, and recommendations for the siting and operation of geothermal power plants.

This activity features a demonstration (with full class participation) to illustrate radioactive decay by flipping coins. The activity visually shows students the concepts of exponential decay, half-life and randomness. This activity is ideal for large lecture classes. The site provides teaching tips, a detailed description of the activity, and links to additional references and resources.

This module addresses how to determine the size of a ton of rock of a given composition and invites the student to figure out how to solve the problem. Students recreate spreadsheets, shown in a Powerpoint module, on their own with formulas that answer various pieces of the overall question. This module is the third in a series of six that examine the density of planets and rocks, and was designed for an undergraduate class where students look at geological questions mathematically and may spend more time on the math than on the geology. The site includes teaching notes and tips, and links to teaching materials and additional resources.

In this activity students study some applications of knowing the density of rocks. One set of applications involves the stress, strength, and factor of safety for a rock roof resting on one or more columns in an underground room. A second set of applications involves the normal and shear stresses, cohesion force, and inclination angle for a slab of rock resting on an inclined surface. Students recreate spreadsheets shown in a Powerpoint module with formulas that answer various pieces of an overall question. This module is the fourth in a series of six that examines the density of planets and rocks, and was designed for an undergraduate class where students are asked to look at geological questions mathematically and may spend more time on the math than on the geology. This site includes teaching notes and tips, and links to teaching materials and additional resources.

This exercise has students determine how fast a dinosaur was moving based on the tracks it made. It allows students with minimal quantitative background to become motivated and begin to develop an appreciation for dimensional analysis as they see whether or not they could outrun the track-making dinosaurs. Measurements from any dinosaur track site can be used in this activity. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

Students completing this homework and in-class exercise use historical data from small earthquakes to estimate the recurrence interval of They are encouraged to examine sampling limitations, thoughtfully deal with outliers, compare the results of various techniques and consider the societal impacts of their results. This activity is designed for the Pacific Northwest, but could easily be altered for any other area. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

This activity uses an analogy to illustrate the scale of geologic time and our limited view of the Earth's history. It relates the history of the Earth to a drive across the country. The drive is 4560 km (rough distance between Washington D.C. and Seattle), with 1 km equaling one million years of Earth's history. This analogy is used by the author as a springboard to talk about the limits of our personal perceptions and experiences when making conclusions. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

This homework exercise is designed to familiarize students with earthquake shaking, acceleration, intensity and hazards, including the quantitative measurement of these properties. Students analyze real earthquake data to determine the damage to their homes. By using students' own homes, they see the impacts of shaking, hazard, and intensity in a more personal, connected way. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.

In this activity students devise a way of graphically plotting the density variations vs. depth in the Earth. They recreate spreadsheets, shown in the Powerpoint module, with formulas that answer various pieces of the overall question. This module is the sixth in a series of six that examine the density of planets and rocks, and was designed for an undergraduate class where students are asked to look at geological questions mathematically and may spend more time on the math than on the geology. The site includes teaching notes and tips, and links to teaching materials and additional resources.
