Social Development in the late 1800s
This video is accompanied by text. "As inferior living and working conditions, along with corrupt city governments, were creating a bleak future for many U.S. cities, reformist leaders emerged to fight for the rights of the urban masses. Social crusaders attempted to eliminate the violent crime, prostitution, unsanitary living conditions, and unsafe work environments that were plaguing the quickly expanding cities.
During the late 1800s, activists established settlement houses to provide
Origins of Progressivism
This video is accompanied by text. "Bounded by the end of the nineteenth century and the American entry into World War I, the Progressive Era brought dramatic changes to the nation’s economic, political, and social sectors. Progressives included both men and women from various ethnic groups, classes, and occupations who challenged traditional attitudes about the American way of life.
The reformers fought to overcome inefficiencies in government, corrupt political machines, and the inade
A comical show about AJ and the crew who travel back in time to late 19th century to talk to Nellie Bly. Nellie Bly was a journalist who faked her own insanity in order to investigate the terrible conditions of America's asylums.
This video explains the parallel structure concept and provides many examples. In the video the narrator explains parallel structure means that parts of a sentences that have the same grammatical function and have the same grammatical form. She reviews some correct and incorrect examples.
How the Body Works : Skeletal Muscles
The voluntary or skeletal muscle system consists of more than 650 muscles, which produce body movement and help maintain an upright posture. Voluntary muscles are The voluntary or skeletal muscle system consists of more than 650 muscles, which produce body movement and help maintain an upright posture. built onto the skeletal framework in several layers; the ones shown here are those directly under the skin. Facial muscles are involved in speech, eating, and expression. Muscles across the chest
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

SAT Math Functions
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.
Biomes Interactive Site
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
Radioactive Decay Events Model
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.
The Arts in Every Classroom: Historical References in the Arts
Learner Team members and students examine costume designs for Parade, focusing on how the designs help convey character. They interpret works by painter René Magritte and choreographer Alwin Nikolais, discovering influences on the creators of Quidam. They also conduct research into the history of street performance and report their findings, in the role of art historian.
