Muscle Structure and Function
Visit KMSZone.com for more! And here's the last animation done during high school, also the first 'real' one for biology. It explains the details of muscle structure and function.
Balance and flux
Ecosystems and populations of organisms within ecosystems function by the principle of balance and flux. Balance can be thought of as a state of equilibrium, or a state of equal changes between two sides. Flux can be thought of as a rate of flow or changes. Even small changes in an ecosystem's or population's balance and flux could lead to disaster.
Basic economic concepts: Scarcity
Scarcity is a function of time, geography
and production. Scarcity and the fear of scarcity have led to war and
slavery. This is a professionally-produced video of good quality.
Stage Lighting & Managing : How Do Stage Lights Work?
Stage lights are controlled by an operator who presets the various lighting options for the show, and each light can be made brighter, softer or colored. Understand the function of stage lights with tips from an experienced stage manager in this free video on theater lighting.
Caves: Extreme Conditions for Life
For certain life forms on Earth, conditions that humans and other familiar organisms find hospitable can actually be deadly. Instead of a moderate climate with an atmosphere rich in nitrogen and oxygen, these organisms thrive in very hot or very cold temperatures, or in caves or deep waters where no light penetrates. In this video segment adapted from NOVA, scientists analyze communities of cave-dwelling microbes that live off simple inorganic compounds like iron and sulfur. Based on their findi

This course introduces the basic concepts and methods of statistics with applications in the experimental biological sciences. Demonstrates methods of exploring, organizing, and presenting data, and introduces the fundamentals of probability. Presents the foundations of statistical inference, including the concepts of parameters and estimates and the use of the likelihood function, confidence intervals, and hypothesis tests. Topics include experimental design, linear regression, the analysis of

This video offers a brief glimpse of understanding function questions on the SAT Math exam. (01:26)
In this module you will study the motion of a vibrating string under undamped and damped conditions. There are interactive exercises to link everyday experiences with mechanics and mathematics. In particular, you will derive the equation which governs the motion of a vibrating string; study the motion of a vibrating string in a vacuum and in a fluid; compare real experimental data with theoretical predictions. Integrating the concepts of higher math with their applications in science and engine
The wondrous flight of millions of monarch butterflies from their roosts in the Sierra Madre mountains of Mexico has long captured the imagination of scientists, nature lovers and tourists. Each spring, the butterflies begin their remarkable journey north. They travel thousands of miles on a trek that provides them with optimal breeding conditions and ultimately ensures the survival of the species. This video segment from Nature captures the butterflies' spring awakening. Run time 03:02.
The distribution of plants and animals around the world is anything but random. Instead, it is a result of the interplay of individual environmental tolerances of species and the environmental conditions, especially variations in temperature and precipitation. These interactions result in biomes, the categories into which ecologists organize similar communities of plants, animals, and the environmental conditions in which they live. This interactive resource adapted from NASA features some of th
The EJS Radioactive Decay Events Model simulates the decay of a radioactive sample using discrete random events. It displays the number of events (radioactive decays) as a function of time in a given time interval. You can change the initial number of nuclei, the decay constant and the time interval for the event distribution.

The Horn of Africa has been experiencing exceptional droughts over the last decade. Using data collected from the NOAA POES satellite, changes in the severity of the drought conditions in the Horn and around the world are shown.
Given the aims of the founders of the London School of Economics, it is not surprising that accounting should have been taught at the School from soon after its establishment. An early focus on teaching practical accounting, with professional practitioners as teachers, was gradually supplanted by approaches informed by the economics of decision-making in conditions of scarce resources. By the 1930s, the Department of Business Administration provided an intellectual basis for thinking about finan

A partir du VIII siècle, environ des esclaves africains ont été vendus en Afrique du Nord et Arabie. Du XVIe au XIXe siècle, le commerce des esclaves ou la traite négrière a pris de l'ampleur : Ce furent d'abord les Portugais et les Espagnols qui s'adonnent à ce trafic. Plus tard, les Français, les Anglais, les Hollandais et les Allemands en firent de même. En Afrique des millions d'hommes et de femmes ont ainsi été faits prisonniers, transportés par bateaux et vendus comme esclaves
In this video, the instructor talks about trigonometric functions as they relate to right triangles. He defines each function and how to find it using the different sides of right triangles. Then, he does example problems using the definitions of the trigonometric functions defined at the beginning. There is a buzzing sound in the background of this video, but the instructor is still able to be heard well.
