The Oort Cloud: Crash Course Astronomy #22
The Oort Cloud: Crash Course Astronomy #22 Teacherflix 5 Views • 2 years ago

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short-period comets, and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer to the Sun and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.

19th Century Reforms: Crash Course US History #15
19th Century Reforms: Crash Course US History #15 Teacherflix 4 Views • 2 years ago

In which John Green teaches you about various reform movements in the 19th century United States. From Utopian societies to the Second Great Awakening to the Abolition movement, American society was undergoing great changes in the first half of the 19th century. Attempts at idealized societies popped up (and universally failed) at Utopia, OH, New Harmony, IN, Modern Times, NY, and many other places around the country. These utopians had a problem with mainstream society, and their answer was to withdraw into their own little worlds. Others didn't like the society they saw and decided to try to change it. Relatively new Protestant denominations like the Methodists and Baptists reached out to "the unchurched" during the Second Great Awakening, and membership in evangelical sects of Christianity rose quickly. At the same time, Abolitionist societies were trying to free the slaves. Americans of the 19th century had looked at the world they were living in and decided to change it.

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.
Of all of the reform movements of the 1800s, few were as impactful as the movement to abolish slavery:

Look at all the colors I can see!
I see big red apples in the tree.
I can see my yellow cat,
I can see my big blue hat.
Oh, look at all the colors I can see!

Look at all the colors I can see!
I can see green leaves up in the tree.
I can see my big orange ball,
Purple flowers by the wall.
Oh, look at all the colors I can see!

Look at all the colors I can see!
I can see the brown trunk of the tree.
I see white clouds in the sky,
And a blackbird flying by.
Oh, look at all the colors I can see!

(Spoken)
Red and yellow make orange.
Yellow and blue make green.
Blue and red make purple.
Red and white make pink.
White and black make gray.
All the colors make brown!

Look at all the colors I can see!
Now I see gray rain clouds by the tree.
If we get a few rain showers,
Then I'll see big bright pink flowers.
Oh, look at all the colors I can see!

I see colors of the rainbow
in the world that's all around me,
Oh, look at all the colors I can see!

Japan in the Heian Period and Cultural History: Crash Course World History 227
Japan in the Heian Period and Cultural History: Crash Course World History 227 Teacherflix 3 Views • 2 years ago

In which John Green teaches you about what westerners call the middle ages and the lives of the aristocracy...in Japan. The Heian period in Japan lasted from 794CE to 1185CE, and it was an interesting time in Japan. Rather than being known for a thriving economy, or particularly interesting politics, the most important things to come out of the Heian period were largely cultural. There was a flourishing of art and literature in the period, and a lot of that culture was created by women. The Tale of Genji by Murasaki Shikibu was the classic piece of literature of the day, and it gave a detailed look into the way the Aristocrats of the Heian period lived. While this doesn't give a lot of insight into the lives of daily people, it can be very valuable, and the idea of approaching history from a cultural perspective is a refreshing change from the usual military or political history that survives from so many eras.

Expansion and Consequences: Crash Course European History #5
Expansion and Consequences: Crash Course European History #5 Teacherflix 3 Views • 2 years ago

European exploration had a lot of side effects. When the Old World and the New World began to interact, people, wealth, food, animals, and disease began to flow in both directions. In the New World, countless millions were killed by smallpox, measles, and other Old World diseases. Old World animals changed life in the New World irrevocably, and the extraction of wealth and resources from the Americas ultimately contributed to the development of the Atlantic Slave Trade. So, it was an exchange with a lot of downside, especially for non-Europeans.
