Passing Gases: Effusion, Diffusion, and the Velocity of a Gas - Crash Course Chemistry #16
We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life), how a gas moves is more complex than it seems at first. In this episode, Hank describes what it means when we talk about the velocity of a gas - to understand gas velocity, we have to know what factors affect it, and how. Hank also teaches you about effusion, diffusion, and concentration gradients, before showing off a cool experiment that physically demonstrates the things you have just learned. Sound exciting enough for you? Let's get started. *Special Thanks to Matt Young at the University of Montana (Geosciences Department, Environmental Biogeochemistry Lab) who helped with the chemical demonstrations.* Pssst... we made flashcards to help you review the content in this episode!

How can the color “red” be a global commodity? How can the way a statue stands be a sign of cultural exchange?

Who Gets to Be a "Real" Artist? (Amateur and Outsider Art): Crash Course Art History #13
For centuries, “official” art spaces have shaped whose work gets taken seriously. But there are no required qualifications for making art! In this episode of Crash Course Art History, we’ll explore amateurs and outsiders.

Women in the 19th Century: Crash Course US History #16
In which John Green finally gets around to talking about some women's history. In the 19th Century, the United States was changing rapidly, as we noted in the recent Market Revolution and Reform Movements episodes. Things were also in a state of flux for women. The reform movements, which were in large part driven by women, gave these self-same women the idea that they could work on their own behalf, and radically improve the state of their own lives. So, while these women were working on prison reform, education reform, and abolition, they also started talking about equal rights, universal suffrage, temperance, and fair pay. Women like Susan B. Anthony, Carry Nation, Elizabeth Cady Stanton, the Grimkés, and Lucretia Mott strove tirelessly to improve the lot of American women, and it worked, eventually. John will teach you about the Christian Temperance Union, the Seneca Falls Convention, the Declaration of Sentiments, and a whole bunch of other stuff that made life better for women. Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. Few women were as vocal for women's rights during the 19th century as Susan B. Anthony: https://www.commonlit.org/texts/the-life-s-work-of-susan-b-anthony Anthony worked for women's right to vote alongside great women like Sojourner Truth, who stressed the importance of intersectional feminism in her influential “Ain't I a Woman?” Speech: https://www.commonlit.org/texts/ain-t-i-a-woman Chapters: Introduction: How Women Transformed Pre-Civil War America 00:00 Women's Experience During Colonial America 0:59 Women's Participation in the Political Process 1:35 Women's Participation in the Market Revolution 2:49 Mystery Document 3:46 Women's Opportunities for Work 4:52 Women's Participation in Reform Movements 5:40 Women's Suffrage 7:24 Women in the Abolitionist Movement 8:04 Opposition to Women's Rights 8:56 The Suffragettes 9:36 The Patriarchy 11:20 Women's Participation in Reform Movements 12:03 Credits 12:38 Crash Course is on Patreon!

How Are We All Part of Ending Outbreaks? Crash Course Outbreak Science #15
Over the course of this series, we've seen that outbreak science is actually MANY sciences, including biology, epidemiology, sociology, and even economics! Because outbreak science is an interdisciplinary field, everyone has a role to play in ending outbreaks, including you! In this final episode of Crash Course Outbreak Science, we'll take a look at how different fields come together to prepare for and prevent outbreaks. This episode of Crash Course Outbreak Science was produced by Complexly in partnership with Operation Outbreak and the Sabeti Lab at the Broad Institute of MIT and Harvard—with generous support from the Gordon and Betty Moore Foundation.
