US Geopolitics through Time for English Learners Study Guide 1: First animal and human settlement in the Americas
I highly recommend that English learners become familiar with the key terms before watching the video.
Section 1 – The land of North America Key Terms migration glacier, glaciation coast Appalachian, Rocky, Sierra Nevada mountain ranges The Great Plains The Great Lakes the Mississippi River coal
Discussion Questions 1. How big is N America compared to Eurasia and Africa? 2. Do you think Europe and Asia are separate continents? 3. Why are the Great Plains important in this story?
Section 2 – Geological History Key Terms Antarctica Pangaea the isthmus of Panama fauna, megafauna speciation outcompete displace marsupial mammals, placental mammals
Discussion Questions 1. What was the Great American Interchange? 2. Why is it significant that S America was isolated for tens of millions of years? 3. Do you know of any other great interchanges in world history?
Section 3 – Humans in America Key Terms Beringia Ice Age peopling of the Americas shoreline extinction event
Discussion Questions 1. When did humans come to the Americas? How does this compare with human settlement of East Asia and Europe? 2. Why do you think so much megafauna went extinct around 15 ka? (Another theory which isn't mentioned in the video is climate change; the end of the ice age may have led to extinction.) 3. What are some effects on the ecosystem of such mass extinctions?
Discussion Questions 1. Why was Clovis point technology so important for humans? 2. How does the location of Clovis sites relate to modern human settlement? 3. Why didn’t North America have potatoes or any production animals? (The answer for potatoes was not given in the video. Although potatoes are from S America, why do you think they didn't reach N America?)
