How Will Climate Change Continue to Affect Us?: Crash Course Climate and Energy #8
Our warming planet isn’t just a threat to future generations; it’s a threat to us right now.

Structure of the Court System: Crash Course Government and Politics #19
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.

Protests East and West: Crash Course European History #45

To Kill a Mockingbird, Part 1 - Crash Course Literature 210
In which John Green teaches you about Harper Lee's famous novel, To Kill a Mockingbird. John will cover a bit about Harper Lee's personal life, (seeing as this novel has some autobiographical elements) and her long association with Truman Capote, who figures as a character in the book. You'll get an overview of the plot, and we'll talk a bit about Mockingbird as an example of bildungsroman (again) and Southern Gothic, and look into the novel as a commentary on the racism and patriarchy of the Alabama in which Harper Lee grew up.

Climate change has no bias, but our societies and systems do. And although it’s a danger to all of us, a changing climate affects some groups disproportionately, raising issues of justice and equity.

Alkanes: Crash Course Organic Chemistry #6
Alkanes are kind of the wallflowers of organic chemistry, but they still have important functions in the world around us. In this episode of Crash Course Organic Chemistry we’re building our knowledge of organic molecules by learning all about these so called couch potatoes from how they are separated from crude oil to how to use Newman projections to predict torsional strain and steric hinderance.

The American Revolution: Crash Course Black American History #8
When we talk about the American Revolution and Revolutionary War, the discussion often involves lofty ideals like liberty, freedom, and justice. The Declaration of Independence even opens with the idea that "all men are created equal." But it turns out, the war wasn't being fought on behalf of "all men." The war was mainly about freedom for white colonists, and liberty, justice, and the pursuit of happiness didn't apply to the Black people living in the British colonies. During the war, Black people took up arms on both sides of the conflict, and today we're going to learn how and why they participated.

Political Campaigns: Crash Course Government and Politics #39
So political campaigns are a pretty big deal in the United States. For instance the 2012 presidential election clocked in at the most expensive ever - at around $6 billion dollars! Needless to say, money plays a very big role in American elections. So today, Craig is going to take a look at why we have campaigns in the first place, why the campaign seasons run for so long, and of course why campaigns cost so much.

If One Finger Brought Oil - Things Fall Apart Part 1: Crash Course Literature 208
In which John Green teaches you about Chinua Achebe's 1958 novel, Things Fall Apart. You'll learn about Igboland, a region in modern-day Nigeria, prior to the arrival of the British Empire. Achebe tells the story of Okonkwo, an Igbo villager who has worked his way up from life as a sharecropped and become a respected leader in his community. Okonkwo has a tragic fall and is exiled. And then the trouble starts. British missionaries arrive and change everything. Things Fall Apart has a lot to say about colonization and even something to say about decolonization.
