  • Jupiter: Crash Course Astronomy #16

    Jupiter is the biggest planet in our solar system. The gas giant is NOT a failed star, but a really successful planet! It has a dynamic atmosphere with belts and zones, as well as an enormous red spot that’s actually a persistent hurricane. Jupiter is still warm from its formation, has an interior that’s mostly metallic hydrogen, and may not even have a core.

  • Solutions: Crash Course Chemistry #27

    This week, Hank elaborates on why Fugu can kill you by illustrating the ideas of solutions and discussing molarity, molality, and mass percent. Also, why polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes. All that plus Henry's Law and why Coke = Burps.

  • American Imperialism: Crash Course US History #28

    In which John Green teaches you about Imperialism. In the late 19th century, the great powers of Europe were running around the world obtaining colonial possessions, especially in Africa and Asia. The United States, which as a young country was especially susceptible to peer pressure, followed along and snapped up some colonies of its own. The US saw that Spain's hold on its empire was weak, and like some kind of expansionist predator, it jumped into the Cuban War for Independence and turned it into the Spanish-Cuban-Phillipino-American War, which usually just gets called the Spanish-American War. John will tell you how America turned this war into colonial possessions like Puerto Rico, The Philippines, and almost even got to keep Cuba. The US was busy in the Pacific as well, wresting control of Hawaii from the Hawaiians. All this and more in a globe-trotting, oppressing episode of Crash Course US History.

    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. As America transitioned from the 19th to the 20th century, it experimented with imperialism through war and annexation; one of the most lasting effects of this time was the annexation of Hawaii, America's 50th state: https://www.commonlit.org/texts/the-1897-petition-against-the-annexation-of-hawaii
    America’s imperial aims continued for decades, particularly with the Monroe Doctrine: https://www.commonlit.org/texts/the-monroe-doctrine-and-american-imperialism

  • Separation of Powers and Checks and Balances: Crash Course Government and Politics #3

    In which Craig Benzine teaches you about the US Governments Separation of powers and the system of checks and balances. In theory, the Legislative Branch, the Executive Branch, and the Judicial Brach are designed to keep each other in check and to keep any branch from becoming too powerful. In reality, the system was designed to keep the President from becoming some kind of autocrat. For the most part, it has worked. Craig will call in the clones to explain which powers belong to which branches and to reveal some secret perks that the Supreme Court justices enjoy.
