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

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

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.

Renal Pathophysiology
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

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

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
