In which John Green teaches you about the Wild, Wild, West, which as it turns out, wasn't as wild as it seemed in the movies. When we think of the western expansion of the United States in the 19th century, we're conditioned to imagine the loner. The self-reliant, unattached cowpoke roaming the prairie in search of wandering calves, or the half-addled prospector who has broken from reality thanks to the solitude of his single-minded quest for gold dust. While there may be a grain of truth to these classic Hollywood stereotypes, it isn't a very big grain of truth. Many of the pioneers who settled the west were family groups. Many were immigrants. Many were major corporations. The big losers in the westward migration were Native Americans, who were killed or moved onto reservations. Not cool, American pioneers.

America’s Westward expansion was fueled by both Manifest Destiny and a desire to grow the nation and its resources — though at a cost: https://www.commonlit.org/texts/manifest-destiny
As Americans continued to stream West under the name of Manifest Destiny, American Indians saw their lives changed forever as they moved from practicing resistance to lives on reservations: https://www.commonlit.org/text....s/from-resistance-to

In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years' War, which is often called the French and Indian War in the US, laid a lot of the groundwork for the Revolution. More confusing? Why does this war have two names? Why were the French and Indians fighting each other? The Seven Years' war was actually a global war that went on for nine years. I think I'm having trouble making this clear. Anyway, the part of this global war that happened in North America was the French and Indian War. The French and Indian tribes were the force opposing the British, so that's the name that stuck. Let's get away from this war, as it makes my head hurt. Other stuff was going on in the colonies in the 18th century that primed the people for revolution. One was the Great Awakening. A religious revival was sweeping the country, introducing new ideas about religion and how it should be practiced. At the same time, thinkers like John Locke were rethinking the relationship between rulers and the ruled. So in this highly charged atmosphere, you can just imagine what would happen if the crown started trying to exert more control over the colonies. The colonists would probably just rise up, right? We'll see what happens next week.

Hank veers away from human anatomy to teach us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists. They are by far the most abundant organisms on Earth and are our oldest, oddest relatives.

In the late 19th and early 20th centuries, Black American Women were struggling with both racism and misogyny as they fought for their rights. Black Women formed clubs and organized to make sure civil and political rights were extended to ALL Black people, not just Black men. These clubs were grass-roots organizations of middle-class women who were often only one generation removed from slavery. Today we'll learn about the origins of these clubs and some of the notable women who drove this movement.

Much like a cell membrane, our atmosphere forms a protective boundary between outer space and the biosphere that allows for all life to exist on Earth’s surface. Today, we’re going to talk about its composition and layers (the troposphere, stratosphere, mesosphere, and thermosphere), follow the path of a sunbeam of light as it travels through space and (potentially) reaches Earth’s surface, and discuss how the greenhouse effect can be both a good and bad thing!

We’ve talked about how broad a concept “the media” really is – and given that, it can be hard to keep track of all the different forces that constitute “the media.” It can be tough, but it’s not impossible. Today we’re talking about how all those big players fit together and why all those mergers and acquisitions matter to being a media literate citizen.

Today Phil’s explaining the stars and how they can be categorized using their spectra. Together with their distance, this provides a wealth of information about them including their luminosity, size, and temperature. The HR diagram plots stars’ luminosity versus temperature and most stars fall along the main sequence, where they live most of their lives.

Adriene and Jacob teach you all about markets. So, in free market(ish) economies like the United States and most of the world, markets are a big deal. Markets work to produce the stuff that consumers want, and that society needs. Today we'll talk about productive and allocative efficiency, skinny jeans, price signals, and more in this information-dense installment of Crash Course.

The earliest recorded drama in the west arose in Athen, and these early plays grew out or religious ritual.

It's time to start talking about some of the terrible things you can do to your own body, like blood doping. We'll start by explaining the structure and function of your erythrocytes, and of hemoglobin, which they use to carry oxygen. We'll follow the formation and life cycle of a red blood cell, including how its levels are regulated by EPO and its signaling molecules. We'll wrap up by looking at how blood doping works and how it is truly a recipe for disaster.

Today, Craig is going to talk about something you fans out there have been demanding for months - money in politics. Specifically, we're going to talk about special interest groups and their role in the U.S. political system. Special interest groups are groups of individuals that make policy-related appeals to government - like the NRA, AARP, or the U.S. Chamber of Commerce. It's all pretty controversial, as money plays an important role in the policies and people these groups influence, so we'll bring in the clones to argue for and against them.

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other and form an insoluble compound, they suddenly fall out of the solution in what's called a precipitation reaction. In this episode of Crash Course Chemistry, we learn about precipitation, precipitates, anions, cations, and how to describe and discuss ionic reactions.

Educational video for children to learn what the brain is, which are its parts and how it works. The brain is in charge of coordinating all vital functions of our body and gives meaning to what is happening around us. It receives signals from our environment and sends messages to different parts of our body so that they would respond adequately. The brain is divided into three parts: the cerebellum, the encephalic trunk and the cerebral cortex. In this video we're going to look at each part's function with specific examples. The video also explains the division of the brain into two hemispheres: the right hemisphere which is the location of intuition or creativity and the left hemisphere, which controls tasks like calculating, reasoning or language.

This video belongs to a collection of videos about the human body and how it works. Excellent resource for elementary school education.
