Weather Fronts
This video discusses what a front is. They start with an air mass and the transitional zone is called a front. It is hard to tell if it is a cold or warm front. If the warm air is advancing it is a warm front. This video show the symbols that are used by meterologists. It shows how one mass moves over another mass. This is a good, basic video.

The Mole

Using Avogadro's law, the mass of a substance can be related to the number of particles contained in that mass. Chemists have learned how to count molecules by weighing macroscopic amounts. Chemists must measure precise amounts for reactions to occur in an accurate manner. Analytical data and masses from the atomic chart are used to determine the number of atoms in a

Against All Odds - Describing Relationships
'Segments describe how to use a scatterplot to display relationships between variables. Patterns in variables (positive, negative, and linear association) and the importance of outliers are discussed. The program also calculates the least squares regression line of metabolic rate y on lean body mass x for a group of subjects and examines the fit of the regression line by plotting residuals.'

A Nation Divided Unit 9
Although the Civil War is viewed today through the lens of the Union’s
ultimate victory, for much of the war, that victory was far from
certain. By examining the lives of the common soldier, as well as
civilians, this unit examines the uncertainty and horrible destruction
in the war between the states. (This unit includes a facilitator guide,
video, and online text chapter.)

Mass Wasting
Anyone undertaking a building project must understand mass wasting — the downslope movement of earth under the influence of gravity. Various factors in mass wasting, including the rock’s effective strength and pore spaces, are discussed, as are different types of mass wasting such as creep, slump, and landslides. Images of an actual landslide illustrate the phenomeno

Workshop 1: Making an Impact
What would happen if an asteroid were to hit the surface of the earth? How large a crater would the impact create? In this workshop, the ideas of force and motion are introduced, as seventh-grade students drop balls to simulate asteroid impacts. By varying a ball’s mass, the height from which it is dropped, or the material being struck, the students explore what factor

Producing Penicillin
This video segment adapted from A Science Odyssey tells how two
scientists, Howard Florey and Ernst Chain, used the research findings
of Alexander Fleming to turn a natural compound, penicillin, into an
effective treatment for bacterial infections. Their tests in mice and
later in human patients demonstrated penicillin's ability to cure such
infections. After U.S. drug companies figured out how to mass-produce penicillin, its reputation as a "miracle drug" was e

17.433 International Relations of East Asia (MIT)
The aim of this lecture course is to introduce and analyze the international relations of East Asia. With four great powers, three nuclear weapons states and two of the world's largest economies, East Asia is one of the most dynamic and consequential regions in world politics. During the Cold War, East Asia witnessed intense competition and conflict between the superpowers and among the states in the region. In the post-Cold War era, the region has been an engine of the global economy while unde

2.094 Finite Element Analysis of Solids and Fluids (MIT)
This course presents finite element theory and methods for general linear and nonlinear analyses. Reliable and effective finite element procedures are discussed with their applications to the solution of general problems in solid, structural, and fluid mechanics, heat and mass transfer, and fluid-structure interactions. The governing continuum mechanics equations, conservation laws, virtual work, and variational principles are used to establish effective finite element discretizations and the st

National Geographic-Clown Anemonefish and Sea Anemones
In this video, students will witness clown anemonefish live among sea anemones and use the anemones' stinging tentacles as protection. The clownfish use the predator as shelter. They are able to do this due to the mucus on the anemone. This is a great teaching resource for elementary/middle school students. It would work well in conjunction with a science lesson on oceans, fish, and/or animal behavior.This video is a useful resource to help build background knowledge (1:22).

The Viking Age: England and Francia
Scandinavians, popularly known as Vikings, began to explore and settle in Europe from the ninth century. Contemporary Christian writers voiced their dismay at what they saw as the sudden eruption of these savage pagans into their area. Commentators since, down to the 20th century have largely echoed these writers' views, sometimes portraying the Scandinavians as mindless thugs led by psychopaths. In a period when savagery in warfare was commonplace, the Vikings have been placed by some in a spec
