Ghosts of Machu Picchu
Learn the Science
DISCOVER THE INCA
Although considered one of the largest empires of the world, the Inca left little written record of their rise to power in the mid-1400s. Researchers have determined they were fierce warriors, master engineers, and expert builders. Explore their findings with your students.
Ghosts of Machu Picchu (Video)
See how the design of Machu Picchu reveals a remarkable engineering feat by the Inca. (Chapters 4 and 5, approx. 15 min.; Program available after broadcast)


The Lost Empire (Article)
Travel back 500 years to a magnificent society made up of more than 10 million subjects: the world of the Inca.


Outfitting for Battle (Interactive)
Compare Inca and conquistador soldiers to see how markedly their dress and weaponry differed—differences that played a decisive role in the fall of the Inca Empire.


Grass Bridge (Video)
Watch residents of the Peruvian Andes build a traditional and functioning grass bridge—the likes of which enabled the ancient Inca people to flourish for several hundred years. (4:50 min.)


The Great Inca Rebellion (Lesson/Viewing Ideas: Before Watching #1)
Make a timeline of Inca civilization on the board. Have students research and plot when Inca civilization began, when it peaked, and when it fell. Then, have students find and post (above the Inca time line) information about what was going on in Europe and Asia during that time period.
