Demolition, disease, and death: Building the Panama Canal - Alex Gendler

What creates a total solar eclipse? - Andy Cohen

Explore the science of what causes total solar eclipses, and find out how civilizations throughout history reacted to them. -- How can the shadow of the tiny moon eclipse the sight of the gargantuan sun? By sheer coincidence, the disc of the sun is 400x larger than the disc of the moon, but it's 390x farther from Earth -- which means that when they align just right, the moon blocks all but the sun's glowing corona. Andy Cohen details this extraordinary celestial phenomenon (and when it will next occur). Lesson by Andy Cohen, animation by Bevan Lynch.

Demolition, disease, and death: Building the Panama Canal - Alex Gendler

Discover what it took to build the Panama Canal, and how this colossal construction project changed the region. -- In the 19th century, the California gold rush brought thousands of settlers to America's west coast. But finding gold may have been easier than transporting it back east. The only hope for avoiding a grueling six month wagon journey was to travel the narrowest portion of the continent — the 48-kilometer Isthmus of Panama. Alex Gendler details the creation of the Panama Canal. Lesson by Alex Gendler, directed by Cabong Studios.

TED-Ed animators show how two separate techniques -- rotoscoping and more traditional hand-drawn animation -- bring to life the multilayered process of becoming a slam poet.
