Detecting Genetically Modified Food by PCR
Genetic engineering is responsible for the so-called "second green revolution." Genes that encode herbicide resistance, insect resistance, drought tolerance, frost tolerance, and other traits have been added to many plants of commercial importance. In 2003, 167 million acres of farmland worldwide were planted in genetically modified (GM) crops equal to one fourth of total land under cultivation. The most widely planted GM crops are soybeans, corn, cotton, canola, and papaya. Two important tr
The goal of the Genetic Origins Program is to allow students to use their own DNA variations (polymorphisms) as a means to explore our shared genetic heritage and its implications for human health and society. Genetic Origins focuses on two types of DNA variations: an Alu insertion polymorphism on chromosome 16 (PV92) and single nucleotide polymorphisms (SNPs) in the control region of the mitochondrial (mt) chromosome. With two alleles and three genotypes, PV92 is a simple genetic system that il
The Geologic Time Scale
This resource presents a table of the Geologic Time Scale. The time scale begins with a brief description of the Precambrian Era, and proceeds through the Cambrian Period starting 544 million years ago and concluding with the Holocene Epoch of today. The time periods are explained and include the dates, scientific names, historical descriptions, and common names. The table is organized by Era, Period or System, and Epoch or Series.

This interactive mapping system is one component of the U. S. Geological Survey's Framework Studies and Assessment of the Gulf Coast Project. This project provides the geologic, geophysical, and geochemical framework for the region. The mapping system displays different aspects of the energy resources which reside in the Gulf of Mexico Basin, one of the major hydrocarbon producing areas of the world.
Columbia River Basalt Group, Washington, Oregon, and Idaho
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.
TOXMAP is a Geographic Information System (GIS) from the National Library of Medicine that uses maps of the United States to help users visually explore data from the EPA's Toxics Release Inventory. TOXMAP maps show where reported chemicals are released on-site into the air, water, and ground. The maps also identify the releasing facilities, single year releases, and chemical release trends over time.
Systems Design and Administration I, Fall 2007
Course for students in Computer Information Systems or in Computer and Information Technologies programs. This course will instruct students in system administration topics, including computer hardware selection, user account management, file system optimization, and security. Basic system services such as FTP, WWW, email, printer, and DBMS will also be covered. Students will be required to install, configure, and test the services in a server environment. Three lecture hours per week.
The American Jury: Bulwark of Democracy
"The American Jury: Bulwark of Democracy" is a project of the Constitutional Rights Foundation Chicago and is the national expansion of "The American Jury: Past and Present," conducted in Illinois during 1998-1999. Beginning with a two-week institute in July 1999, "The American Jury" focused on the jury system in the United States. its role in American legal, social, and political life; its origins and history; its adaptations to changes in law and American society; its strengths and limitations
Highlight how symbolic operations on a system of linear equations do (or do not) change the graphic or tabular representations of the system. Note that the System Solver is a tool intended to illustrate the rationale behind the symbolic operations used to solve systems of linear equations, and not a way to learn what procedures to follow.
COSEE Great Lakes Workshops
These asynchronous workshops focus on environmental topics related to the Great Lakes region. Subjects covered include: The solid earth system; The bedrock and formation of the Great Lakes; Life and Rocks: Current geological processes; Human impacts [vice-versa!]; and Ocean/lake deep exploration (sink holes, underwater archeology, NOAA's exploration book) studying the bottom, characteristics of the water at depth.
Gulag: Many Days, Many Lives
Millions of prisoners suffered the brutal assault on human dignity that was the Gulag. Many Days, Many Lives presents the history of this system through a browseable archive of video, art, artifacts, photographs, and the life stories of former Gulag prisoners. Online exhibitions take visitors on a thematic exploration of Gulag life, including a virtual tour of the reconstructed camp and museum made possible by the Gulag Museum at Perm-36. Teaching resources for introducing the Gulag's history in
The current online Andes Physics course is intended to be used with most physics textbooks. It supplements the textbook by providing problems for students to solve with the aid of Andes, an intelligent tutoring system developed at the University of Pittsburgh and the United States Naval Academy with funding from the Cognitive Science program of the Office of Naval Research. Students solve typical textbook problems just as they would with pencil and paper, by entering vectors, coordinate systems,
This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
"Introduction to Education: Understanding and Evaluating Education, Spring 2009"
" This class uses K-12 classroom experiences, along with student-centered classroom activities and student-led classes, to explore issues in schools and education. Students in this course spend time each week observing pre-college math and science classes. Topics of study include design and implementation of curriculum, addressing the needs of a diversity of students, standards in math and science, student misconceptions, methods of instruction, the digital divide, teaching through different med
"Environmental Engineering Masters of Engineering Project, Fall 2007"
"This class is one of the core requirements for the Environmental Masters of Engineering program, in conjunction with 1.133 Masters of Engineering Concepts of Engineering Practice. It is designed to teach about environmental engineering through the use of case studies, computer software tools, and seminars from industrial experts. Case studies provide the basis for group projects as well as individual theses. Recent 1.782 projects include the MMR Superfund site on Cape Cod, appropriate wastewate
"The Impact of Globalization on the Built Environment, Fall 2009"
"The course is designed to provide a better understanding of the built environment, globalization, the current financial crisis and the impact of these factors on the rapidly changing and evolving international architecture, engineering, construction fields. We will, hopefully, obtain a better understanding of how these forces of globalization and the current financial crisis are having an impact on the built environment and how they will affect firms and your future career opportunities. We wil

Worldwide Amphibian Declines
AmphibiaWeb is an online system enabling anyone with a Web browser to search and retrieve information relating to amphibian biology and conservation. This site was inspired by the global declines of amphibians, the study of which has been hindered by the lack of multidisplinary studies and a lack of coordination in monitoring, in field studies, and in lab studies. We hope AmphibiaWeb will encourage a shared vision for the study of global amphibian declines and the conservation of remaining amphi
