Biology
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.

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

Decays Let Physicists Look Inside Particles
These pages invite students to test various particles for their decay products. Most particles studied by physicists are unstable; they decay. That is, given enough time by itself, one unstable particle will fly apart into two or more particles. By carefully observing and logically classifying these decays according to some well-understood laws of nature, particle physicists have been able to explain much about the fundamental structure of matter.

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

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
