You may think that things are heated in Washington today, but the Kansas-Nebraska Act of 1854 had members of Congress so angry they pulled out their weapons -- and formed the Republican Party. The issues? Slavery and states' rights, which led the divided nation straight into the Civil War. Ben Labaree, Jr. explains how Abraham Lincoln's party emerged amidst the madness.

Lesson by Ben Labaree, Jr., animation by Qa'ed Mai.

Ethan Perlstein rediscovers the scientists and their research that have changed the way we study the membrane and the cell as a whole.

Explore the creation of China’s Three Gorges Dam, and find out how the hydroelectric plant generates its power.

Uploaded 10-12-20

--

In 2018, a single power plant produced more energy than the world’s largest coal-powered and gas-powered plants combined. China’s Three Gorges Dam relies on running water, and is capable of producing more energy than any other power plant on Earth. So what allows Three Gorges to generate all this power? And how do hydroelectric plants work in the first place? Alex Gendler investigates.

Lesson by Alex Gendler, directed by Franz Palomares.

Dig into the science of how heat pumps both heat and cool a home, and find out the benefits and drawbacks of this technology.

--

Typically, with any piece of technology, you pump one unit of energy in and you get about one out. That’s just the first law of thermodynamics: energy has to be conserved. But there’s a piece of technology called a heat pump, where for every bit of energy you put in, you get three to five times as much heat out. What wizardry is this? Anna Rothschild investigates the science of heat pumps.

Lesson by Anna Rothschild, directed by Kevin Herrmann, AIM Creative Studios.
