There is a documentary about the ancient Muisca tribe in South America and their connection to the El Dorado myth on Netflix and Amazon Streaming called "Secrets: Golden Raft of El Dorado". It's about 45 minutes long and very informative. It's originally from The Smithsonian Channel
I created a handout for students to fill out while following along with the video. There are 35 questions for students to answer or fill in.
A perfect activity for your emergency sub binder! The video is in English so any substitute could go over the handout with your students. I would use this with middle or high school students.
