This is an educational video for children in which they will learn about the excretory system and the organs that make it up. The excretory system is formed by the urinary system and the sweat glands. Its function is to get rid of substances that the body does not need. The main organs of the urinary system are the kidneys. They are dark red, bean-shaped and are responsible for filtering waste from the blood. We also have the bladder, which is a balloon-shaped organ that stores urine. Once it is full, the urine travels out of the body through a tube called the urethra. Finally, we have the skin. Under the skin we can find the sweat glands, which are also responsible for filtering waste from the blood by expelling sweat.

This video is a very useful and interesting resource for children. It is perfect for teaching how the excretory system works. It is an excellent video for primary education.

Scientists tend to be careful and resistant to big claims. So evidence for the possible end of the living world took a while to be seen as such. In this episode of Crash Course History of Science, Hank talks to us about where Climate Science started and how it works today.

Finally, after what seems like eons and eons, the end is nigh. We're talking not only about the end of Crash Course Big History but also the end of everything. The end of humanity and the end of the universe. John and Hank Green will teach you about what the future holds for humanity and the universe. Spoiler alert: in the long, long, long, long, long, long term, it doesn't look good. In the short term though, it's not too bad. But don't lose hope, there is an upside. You'll have to watch the video to find out.

#crashcourse #Black #history

In which Craig Benzine breaks down the different types of bureaucracies. I mean sure, they’re all part of the executive branch, but some work more directly with the President than others. Some bureaucracies exist solely to independently regulate industry whereas others are expected to operate like corporations and make a profit. And on top of all that, some of these agencies have sub-agencies! It can all get pretty complicated, so we’ll try to discuss some of the most significant agencies out there and the ones you hear a lot about on the news. We’ll talk about how they seem to have steadily gained more and more power, and of course, we’ll talk about what all the agencies are for in the first place!

So today Craig is going to talk about where our political opinions come from. Of course, most people’s politics are grounded in their ideologies, but there are also other external influences such as the government itself, interest groups, and the media. So we're going to talk about how these influencers factor into the overall public opinion and how their roles have changed over time. Now this stuff may seem like common sense, but it’s important to know where our opinions come from, especially when you consider how quickly the media landscape is changing.

Last week we introduced the idea of socialization and today we’re talking a little more about how it works, including an introduction to five main types of socialization. We’ll explore anticipatory socialization from your family, the “hidden curriculum” in schools, peer groups, the role of media in socialization, and we’ll discuss total institutions and how they can act as a form of re-socialization.

So we ended last episode at the start of the 20th century with special purpose computing devices such as Herman Hollerith’s tabulating machines. But as the scale of human civilization continued to grow as did the demand for more sophisticated and powerful devices. Soon these cabinet-sized electro-mechanical computers would grow into room-sized behemoths that were prone to errors. But is was these computers that would help usher in a new era of computation - electronic computing.

Oh my, Craig has his work cut out for him this week. The process of how a bill becomes a law can be pretty complex, fraught with potential bill-death at every corner. As if just getting through committee isn’t difficult enough, bills have to navigate a series of amendments and votes in both houses, potentially more committees, further compromise bills, and even more floor votes, just to end up on the chopping block of the President. And then in one fell swoop, the President can stop a bill in its tracks with a veto! But then again, a presidential veto isn’t necessarily a bill’s end either.

As you can see we’ve got to lot to cover, and we’ll be the first to admit this has been covered before, and extraordinarily well might we add, by the folks at School House Rock. But we’ll give it our best shot - without the singing of course. Well, not too much singing anyway.

In which Craig Benzine talks about the structure of the U.S. court system and how exactly it manages to keep things moving smoothly. You'll learn about trial courts, district courts, appeals courts, circuit courts, state supreme courts, and of course the one at the top - the U.S. Supreme Court. It’s all quite a bit to manage with jurisdictions and such, but it's important to remember that the vast majority of cases never even make it to court! Most are settled out of court, but also terms like mootness and ripeness are used to throw cases out altogether. Today, we're going to focus on how cases make it to the top, and next week we’ll talk about what happens when they get there.

So, what is geography? In our first episode of Crash Course Geography, we will endeavor to answer this seemingly simple question with the help of a similarly simple factoid: that the US imports more than 3 billion pounds of bananas from Guatemala each year. But as it turns out, beneath the kinds of factoids we usually associate with Geography are much grander stories that really are Geography. So let's go a little bananas as we explore the sordid history of the Chiquita banana.

Continuing with last week's calculus introduction, Shini leads us through how integrals can help us figure out things like distance when we have several other essential bits of information. Say, for instance, you wanted to know how far your window was off the ground. You can figure that out by using integrals, a tennis ball, and a stopwatch! It's all here in this episode of Crash Course Physics!
