Struggles for Social Justice
The 1960s and early 1970s were characterized by a series of protests as groups that had long felt disempowered sought to make their voices heard. California was the heart of many of these new movements. The protests put into motion by the Civil Rights movement evolved to address social justice issues affecting many groups, including students facing the draft, ordinary people protesting the war, farm workers fighting for better working conditions, Chicanos expressing a new identity, and African A
Environmental Decision Making
Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity. By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown. EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the mode

This USGS site provides access to water resources data collected at approximately 1.5 million sites in all 50 states, the District of Columbia, and Puerto Rico. The site features real-time and historical data retrievable by geographic area for surface water, groundwater, and water quality conditions such as temperature, specific conductance, pH, nutrients, pesticides, and volatile organic compounds. The site also includes an extensive inventory of information about data collection sites at strea
North American Slave Narratives
This site offers more than 250 memoirs, autobiographies, and narratives from individuals who were slaves. An African king who was sold into slavery, the dress maker for Mary Todd Lincoln, the servant of Robert E. Lee during the Civil War, and the nurse of George Washington are included, as are stories of Sojourner Truth, George Washington Carver, Booker T. Washington, and others. These firsthand accounts describe the conditions and sufferings of slaves and a number of escapes to freedom.
The Biology course is a first-year course in biology at the high school level. The course emphasizes a multi-representational approach to algebra, with concepts, results, and problems being expressed graphically, analytically, and verbally. The course uses four themes to organize important concepts throughout the course: science, technology, and society; evolution; the relationship between structure and function; and science as a process.
Substance Abuse and the Family
This course focuses on families with members who are substance abusers, and the ways in which these families function. The course explores the methods and resources available for helping such families.
Calculus I, Summer 2007
This course is an introduction to differential and integral calculus. It begins with a short review of basic concepts surrounding the notion of a function. Then it introduces the important concept of the limit of a function, and use it to study continuity and the tangent problem. The solution to the tangent problem leads to the study of derivatives and their applications. Then it considers the area problem and its solution, the definite integral. The course concludes with the calculus of element
Teacher's Guide to the Occupational Outlook Handbook
This site describes hundreds of jobs. For each job, it tells what workers do, working conditions, the training and education needed, earnings, and expected job prospects. Job search tips, information about the job market in each state, articles about specific occupations and industries, and additional career information are included.
Photoelectric Effect Virtual Lab
The Photoelectric Effect Virtual Lab was designed with the intent that students and teachers might explore one of the most important, non-classical, behaviors of light - the photoelectric effect. The ability of light, under the right conditions, to liberate electrons from the surface of metals, was one of the most profound mysteries of the late 19th and early 20th centuries. In this Virtual Lab, students will graphically explore the behavior of light with metals.
The importance of the kidneys is most clearly demonstrated in the presence of pathophysiologic states. The kidneys play a central role in the maintenance of the internal milieu by balancing fluid, electrolytes, and hydrogen ions to provide optimal conditions for molecular, cellular, and body system function. They also serve as the major excretory organ for metabolic byproducts, drugs, and other organic substances. Finally, the kidneys are an important endocrine organ, producing vasoactive factor
The Introduction to Cardiovascular Pathophysiology course provides the students with two main objectives. It delineates the material students are expected to understand and have recalled from the basic cardiac physiology lectures and it expands on the discussion of the hemodynamic perturbations of cardiac function.
Calculus on the Web
COW is an internet utility for learning and practicing calculus. The principal purpose of COW is to provide you, the student or interested user, with the opportunity to learn and practice problems in calculus (and in the future other topics in mathematics) in a friendly environment via the internet. The most important feature of the COW is that you get to know whether your answer is correct almost immediately. It is as if you had a tutor looking over your shoulder and helping you along as you wo
The Snowball Earth
This website contains an informational paper by Paul Hoffman and Daniel Schragg at Harvard University. The paper describes many lines of evidence supporting a theory that the entire Earth was ice-covered 600-700 million years ago. Each glacial period lasted for millions of years and ended violently under extreme greenhouse conditions. These climate shocks triggered the evolution of multicellular animal life, and challenge long-held assumptions regarding the limits of global change. Users can rea
Robert Owen and New Lanark
Childcare, education, working conditions, healthcare, crime â€¦ these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early
Radioactive Decay Model
The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot.
Lennard-Jones Potential Model
The EJS Lennard-Jones Potential model shows the dynamics of a particle of mass m within this potential. You can drag particle to change its position and you can drag the energy-line to change its total energy. The Lennard-Jones potential function is a reasonably accurate model of interactions between noble gas atoms. The binding energy epsilon is the depth of the potential well and minimum molecular separation are set equal to unity. This simulation uses uses a natural system of units the m
Unit 2 - Participatory facilitation for household food security
Unit 2 is dedicated to the facilitation process and skills to help you facilitate HFS projects well. In this unit we will look at participatory and facilitation techniques in relation to Household Food Security. We will examine he background and history of community development and the difference between the approaches that developed. We will describe the community development approach we will be using for the Household Food Security Programme with its content modules based on household food se

The site presents data, metadata, and graphics by allowing the user to select categories and then click a button for the desired function. Data can be displayed as a list, a time series plot, or in terms of recent trends, relevance, and correlation. Measured parameters include weather, oceanographic and climate data, sea ice data, and fisheries and other biological data. The sit
2009 National Hydrologic Assessment
This site from the Hydrologic Information Center of the National Weather Service discusses the flood risk in the United States. Maps and satellite images support the text. The site also provides information about snow levels, stream flow, soil conditions, forecasts and outlooks.
Stellar Wind Disruption by an Orbiting Neutron Star: High X-Ray Luminosity
A tiny neutron star orbits incessantly around a massive star with a diameter a million times larger than its own. The high luminosity of the massive star drives a strong wind from its surface. The neutron star crashes through this wind at over 300 kilometers per second. The gravity and X-ray luminosity of the neutron star act to disrupt the wind, producing an extended wake of dense gas trailing behind the neutron star. This simulation, in the reference frame of the neutron star, shows conditions
