This site is a comprehensive list of reading materials covering the evolving research topics of Complex Adaptive Systems (CAS) and Agent Based Computational Economics (ACE). This continuously updated site is a source of readings for the weekly interdisciplinary Complex Adaptive Systems Workshop at Iowa State University. The reading materials are listed according to category headings. Each listing includes a short summary of the material or simply the reference information. Many natural systems, and increasingly many artificial (man-made) systems as well, are characterized by apparently complex behaviors that arise as the result of nonlinear spatio-temporal interactions among a large number of components or subsystems. Examples of such natural systems include immune systems, nervous systems, multicellular organisms, ecologies, and insect societies.

The site features the use of models, datasets and visualizations in teaching. The site features a collection of data-rich resources, example teaching activities and visualizations that illustrate oceanography topics. Materials from the 2005 workshop on teaching oceanography are also included.

The emerging field of biocomplexity provides a multidisciplinary approach to looking at complex, interrelated systems. Biological, geological, chemical, physical and human elements are all part of biocomplexity. This site contains a variety of resources for faculty members who teach undergraduate courses related to biocomplexity, including biological, geological, chemical, physical and human systems. You will find links to activities and assignments, internet and computer resources, publications, presentations from the 2003 workshop on Teaching Biocomplexity in the Geosciences, a group listserv, and lots of creative ideas for teaching biocomplexity in your own classroom.

This website from the "On the Cutting Edge" workshop series is designed for faculty who teach undergraduate geochemistry and for geochemistry students. Here you will find a growing collection of materials for teaching geochemistry, such as classroom activities and a collection of internet resources. A database of geochemical analytical equipment provides information about instruments across the country that is available for use. The site also contains presentations and discussions from the spring 2005 workshop on Teaching Geochemistry.

Teaching Geoscience with Visualizations brings together the expertise of visualization designers, educators, and cognitive scientists to provide useful information on how to employ quality visualizations of geoscience topics in the classroom. The website offers pedagogical information on what constitutes a "good" educational visualization, tips and tools educators can use to create their own visualizations, essays and posters from participants in a visualization workshop, teaching activities which employ visualizations, and a large collection of links to quality visualizations of geoscience topics.

This site from the "The On the Cutting Edge" workshop series features a wealth of ideas, teaching examples and web-based resources that are useful for teaching undergraduate hydrogeology.

This site from the "On the Cutting Edge" workshop series features a collection of resources for teaching mineralogy at the undergraduate level. These digital teaching materials are designed for faculty to use while designing new courses, enhancing existing courses, or simply looking for new ideas in teaching mineralogy. Students will also find this collection helpful for finding supplemental study materials and for doing research projects in mineralogy.

This site is a clearinghouse for a variety of educational and supporting materials for teaching igneous and metamorphic petrology. Some features of the site are a collection of classroom and laboratory activities, teaching materials such as lecture notes and Power Point presentations, a database of geochemical instruments available for use at various institutions, a collection of petrology syllabi, and listserv discussion groups. These collections reflect the contributions of faculty members from across the country, and will continue to grow as new materials and tools are developed.

This site from the "On the Cutting Edge" workshop series contains a collection of activities that can be used in undergraduate structural geology courses. The collection includes lab exercises, classroom activities, problem sets and more.

This site from Tulane University consists of a lecture by Dr. Stephen Nelson on tectosilicate, oxide and carbonate minerals. The site features a table and description of the minerals in each group, including the nine types of SiO2, the different feldspars, and the calcite group. Optical and physical properties are explained, as well as the environment in which each mineral crystallizes.

These lecture notes discuss equilibrium crystallization in two component systems. Isotherms and boundary curves are introduced in this section. Other topics discussed include congruently melting intermediate compounds, incongruently melting compounds, and binary solid solution in ternary systems. Annotated phase diagrams are included throughout the text. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html

This 37-slide PowerPoint presentation covers thermodynamics in metamorphic rocks. Gas phases are described in terms of gas pressure-volume relationships in light of the ideal gas law. T-X relationships and compositional variations are considered in describing qualitative solutions to dehydration reactions. The presentation covers geothermobarometry in detail, using P-T diagrams to illustrate the concepts. This resource is part of the Teaching Petrology collection. http://serc.carleton.edu/NAGTWorkshops/petrology03/index.html

These lecture notes provide an introductory lesson in thermodynamics to help students better understand the relationships depicted on phase diagrams. The first and third laws of thermodynamics and Gibb's Free Energy are discussed. Solid-solid reactions are covered in the context of the Sillimanite-Kyanite-Andalusite P-T graph. Devolatization reactions, reaction boundaries, and reaction rates are also covered in the notes. The notes contain many graphs relating pressure, temperature, and Gibb's Free energy.

This online book uses five case studies to investigate whether environmental degradation is worse in poor and minority communities, and if these communities suffer more adverse health effects as a result. The book makes recommendations to decision makers in the areas of public health, research, and education of health professionals, and outlines health policy considerations. It is available online for free, may be printed from the site, or may be ordered as a hard copy from the site.

This report explains how many chemicals used in pesticides, cosmetics, drugs, food, and commerce have not been sufficiently tested to allow a complete determination of their potential hazards. The report uses a model to show how research priorities for toxicity testing can be set. It may be read online, printed, or ordered in hard copy from the site.
