Humans depend on water for drinking, as well as for domestic, agricultural, and industrial activities. Although water is a renewable resource, the water supply is limited and needs to be protected. One way for people to preserve water is to be aware of their own consumption. In this video segment adapted from ZOOM, cast members predict and and then compare how much water they each use during a typical shower. This video could also be used while teaching the scientific process. Closed captioning included. Run time 04:26.

America became dependent on slavery as both the industrial North and the farming South became dependent on cotton. However, states' rights soon made slavery a politicized issue. This video shows how America started to react strongly against the idea of having slaves even if was justified in the South because they made money from them. The Missouri Compromise, abolitionists, Underground Railroad, and others explained.

Carbon nanotubes offer a powerful new way to detect harmful gases in the environment. However, the methods typically used to build carbon
nanotube sensors are hazardous and not suited for large-scale
production. A new fabrication method created by MIT chemists — as simple as drawing a line on a sheet of paper — may overcome that obstacle. MIT postdoc Katherine Mirica has designed a new type of pencil lead in which graphite is replaced with a compressed powder of carbon nanotubes. The lead, which can be used with a regular mechanical pencil, can inscribe sensors on any paper surface. The sensor, described in the journal Angewandte Chemie, detects minute amounts of ammonia gas, an industrial hazard. Timothy Swager, the John D. MacArthur Professor of Chemistry and leader of the research team, says the sensors could be adapted to detect nearly any type of gas. (02:30)

John Green talks about American women in the Progressive Era and, well, the progress they made. So the big deal is, of course, the right to vote women gained when the 19th Amendment was passed and ratified. But women made a lot of other gains in the 30 years between 1890 and 1920. More women joined the workforce, they acquired lots of other legal rights related to property, and they also became key consumers in the industrial economy. Women also continued to play a vital role in reform movements. Sadly, they got Prohibition enacted in the US, but they did a lot of good stuff, too. The field of social work emerged as women like Jane Addams created settlement houses to assist immigrants in their integration into the United States. You'll learn about famous reformers and activists like Alice Paul, Margaret Sanger, and Emma Goldman, among others. (13:30)

This is a 30-minute biography of the life of Thomas Alva Edison, (February 11, 1847 – October 18, 1931) an American inventor, scientist and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb.Dubbed "The Wizard of Menlo Park" (now Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory.

This video is accompanied by text. "The space race grew out of the Cold War between the Soviet Union and the United States. Each of the superpowers wanted to win the race to prove the superiority of not only their technology, but also their own political and social philosophy. On October 4, 1957, Soviet scientists amazed the world by launching into space the first man-made satellite. The nearly 200-hundred-pound Sputnik (Russian for "satellite" or "baby moon") successfully orbited the earth as elated Russians celebrated on the ground. The following month the same team lofted the larger Sputnik II above the earth's atmosphere, this time carrying a dog. The United States, considered by many the world scientific and industrial production leader, had seemingly fallen behind the Soviet Union..." ( Video is well done and professionally produced.)

In today’s video, we discuss a topic critical to understanding economic growth: the power of institutions. (05:18) To better shed light on this, we're going to look at an example that's both tragic and extreme.
In 1945, North and South Korea were divided, ending 35 years of Japanese colonial rule over the Korean peninsula. From that point, the two Koreas took dramatically different paths. North Korea went the way of communism, and South Korea chose a relatively capitalistic, free market economy.
Now—what were the results of those choices?
In the ensuing decades after 1945, South Korea became a major car producer and exporter. The country also became a hub for music (any K-pop fans out there?), film, and consumer products. In stark contrast, North Korea's totalitarian path resulted in episodes of famine and starvation for its people.
In the end, South Korea became a thriving market economy, with the living standards of a developed country. North Korea on the other hand, essentially became a militarized state, where people lived in fear.
Why such an extreme divergence?
It all comes down to institutions.
When economists talk about institutions, they mean things like laws and regulations, such as property rights, dependable courts and political stability. Institutions also include cultural norms, such as the ones surrounding honesty, trust, and cooperation.
To put it another way, institutions guide a country's choices -- which paths to follow, which actions to take, which signals to listen to, and which ones to ignore.
More importantly, institutions define the incentives that affect all of our lives.
Going back to our example, in the years after 1945, North and South Korea took dramatically different institutional paths.
In South Korea, the institutions of capitalism and democracy, promoted cooperation and honest commercial dealing. People were incentivized to produce goods and services to meet market demand. Businesses that did not meet demand were allowed to go bankrupt, allowing the re-allocation of capital towards more valuable uses.
Against that grain, North Korea's institutions produced starkly different incentives. The totalitarian regime meant that the economy was centrally planned and directed. Most entrepreneurs didn't have the freedom to keep their own profits, resulting in few incentives to do business. Farmers also didn't have enough incentive to grow sufficient food to feed the population. This was due in part to price controls, and a lack of property rights.
As for capital, it was allocated by the state, mostly towards political and military uses. Instead of going towards science, or education, or industrial advancement, North Korea's capital went mostly towards outfitting its army, and making sure that the ruling party remained unopposed.
And now, look at how different the two countries are as a result of those differing institutions. When it comes to economic growth, institutions are critically important. A country's institutions can have huge effects on long-term growth and prosperity. Good institutions can help turn a country into a growth miracle. Bad institutions can doom a country to economic disaster.
The key point remains: institutions are important.
They represent the choices that a country makes, and as the Korean peninsula shows you, choices on this scale can have staggering effects on a nation's present, and future.

What factors shape the ways in which the basic resources are exploited by a society? From Southeast Asia to Russia, Africa, and the Americas, the ratios between land availability and the usable labor force were the primary basis of pre-industrial economies, but politics, environment, and culture played a part as well.

Young Agrarians was created as a tool to introduce young people to a new way of looking at agriculture and food production. The project grew out of several concerns: the demise of family farms in America, the rising average age of farmers (65% of U.S. farmers are over 55), and the fact that young people are unaware of the many opportunities in sustainable agriculture and local food systems. Shot during the spring and summer of 2003 on a road trip from Palmer, Alaska, to Tumacacori, Arizona, the film relates the stories of small-scale farmers, ranchers and market gardeners of all ages and backgrounds who have been drawn by their love for the land to undertake the most noble of occupations - growing food. This film expresses both the aesthetic and ethic of small-scale, sustainable farming. America is home to the quintessential industrial farm model, featuring the lonely farmer perched atop multi-zillion dollar farm equipment spreading chemical fertilizers on a 10,000 acre farm. I wanted young people to see something new, to see other young people excited about reconnecting to their roots and to the agricultural history of America. The people in this film have found that growing food is something a little more community-minded, healthful, and reasonable in scale than the industrialized farming we are so aware of today. It is what Wendell Berry calls "the complex accomplishment of knowledge, cultural memory, skill, self-mastery, good sense and fundamental decency - the high and indispensable art - for which we probably can find no better name than 'good farming.'" The most rewarding aspect of production was the opportunity to get to know the individuals who opened their homes, farms, and fields to me. The energy of young people like Dove Miller from the Food for Lane County Youth Farm in Eugene, Oregon, who has since started college; and Kelly Humphry, a fourth generation family farmer from Illinois who moved to California to study organic agriculture and start her own farm is truly inspiring. Most of these folks are still working the same land, getting ready for another busy season. I wanted this film to encourage people to get to know where their food comes from and to support the good farmers who grow it. (7mins)
