This PowerPoint presentation is part of the Whitman College petrology course. This 37-slide presentation starts by presenting a generalized map of the earth's rift system. The composition of mid-ocean ridge basalt is introduced in the context of major-element chemistry, petrography, trace elements, spreading rate, and isotope chemistry. Melt generation in terms of mantle and lithospheric structure is portrayed in a number of schematic diagrams.

This web site is maintained by John Winter of Whitman College, and is an on-line companion to a mineralogy course. The web site contains a course syllabus, PowerPoint presentations and an Excel tutorial. Topics included in the PowerPoint presentations include basic symmetry concepts, 2-D and 3-D translations, crystal properties, and optical mineralogy concepts. Each PowerPoint file can be downloaded and modified to suit the need of the user.

This website describes the animations and software Crystal Movies, XtalDraw, and XPow. Crystal Movies are gif animations that illustrate the evolution of crystal structures as functions of pressure, temperature, chemistry, or orientation. XtalDraw is an interactive Windows-based software that draws ball and stick, polyhedral, and thermal ellipsoid representations of crystal and molecular structures. XPow plots theoretical diffraction patterns of crystalline materials.

Students are introduced to the social and scientific issues surrounding the removal of the Glines Canyon Dam on the Elwha River in Washington state, and conduct a hands-on experiment with real-world application to observe the effects and consequences of removing the dam.

This site features a collection of visual resources illustrating the physical processes that interact to create mountain uplift and erosion. Visualizations include simple animations, diagrams, photographs, and visual output from both experimental and numerical models. These resources can be integrated into lectures, classes, labs or other activities.

This PowerPoint presentation is part of the Whitman College petrology course. This 29-slide presentation covers the compositional evolution of basalt using high field strength, large-ion lithophile, rare earth elements, and isotope geochemistry. Mantle reservoirs (depleted mantle, bulk silicate earth, enriched mantle, prevalent mantle, High mu mantle) are discussed and illustrated. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html

This site features QuickTime and Flash animations that illustrate various aspects of ocean-related activity, including normal, El Nino, and La Nina conditions, ocean plant productivity, causes of upwelling, ocean current patterns, and the origin of tides. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities.

This site provides animations useful for teaching about global cooling and the way glaciation originates. Visualizations illustrate and explain the effects of Milankovitch Cycles and fluctuations in atmospheric carbon dioxide leading to "Snowball Earth" conditions. Resources may be incorporated into lectures, labs, or other activities.

This page provides access to digital maps and supporting material used in developing future scenarios for the Willamette River Basin. The Existing Conditions Section contains digital maps in ArcInfo format organized into six categories called Theme Groups. These maps provide the starting point for development of the maps in the Possible Futures section. In the Futures Scenarios section, maps representing three future scenarios are available. Within each scenario, separate maps are provided for projections at ten year intervals from the year 2000 to 2050 inclusive.

These animations give a paleo perspective on global warming, drought, and global temperature patterns. Climate Research Unit (CRU) data from 1856-1997 are used to create six animations that show globally mapped temperature. Three other animations reconstruct climates for the last 260 years and show spatial patterns of annual temperature anomalies. There are also two drought animations and an interactive presentation on global temperature patterns in past centuries.

This article discusses the merits of case-based learning in an interactive online environment. Researchers used both qualitative and quantitative research over a 2-year period to examine the learning that occurred in a high school context when students were engaged in a case-based multimedia project. Part of the Case It! project, students played both the role of laboratory technician performing and presenting research as well as professionals using the information in their practice. Students were required to use three types of simulation software developed exclusively for the Case It! project. Results were measured using both pre- and post-tests, artifacts students created such as Web posters, records of Internet conferences, and interviews from both the students and the teacher involved in this project. Researches found the online format of the lesson fostered a higher level of questioning and problem solving skills, as well as extended explanations and discussions of ethics in science.

This site is the home page for the petrography and petrology class at Brock University. The site presents general information about igneous petrology, nomenclature and classification information, modal and normative analysis, and the chemistry of igneous rocks. Further topics discussed include fractionation, hybridization and assimilation, and fractional crystallization, as well as types of metamorphism, compositional groups, and Barrovian metamorphism. The information is presented as a sequence of text slides with linked figures.

This collection, from the "On the Cutting Edge" workshop series, features educational resources useful for teaching undergraduate igneous and metamorphic petrology courses. The collection includes lab exercises, classroom activities, problem sets and more.

This site is the homepage for a petrology class. The primary feature of this site is a comprehensive set of lecture notes. There are 18 separate lectures encompassing igneous and metamorphic petrology and related topics. Lectures include text, figures, maps, and tables, and are available in either HTML format or as PDF files. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html

Explain the process of mineral crystallization and phase relationships as a function of temperature and pressure. Topics covered include the phase rule, one-component systems (unary), two-component systems (binary), and three-component systems (ternary), as well as equilibrium crystallization, equilibrium melting, fractional crystallization, and fractional melting. Diagrams and definitions are integrated into the lecture notes.

This PowerPoint presentation is part of the Whitman College petrology course. The presentation covers the crystal behavior of melts through the phase rule, pressure/temperature diagrams, isobaric temperature/weight percentage diagrams, two component eutectic systems, and binary peritectic systems.
