The First Americans: Chapter 1 Lesson 1 Migration to the Americas
How do we study the past? • Archaeologists are scientists who study ancient peoples. • They have used artifacts (objects left behind)and other evidence that supports a theory about the origins of some of the first people to arrive in the Americas. • The evidence indicates that some ancient people crossed a strip of land that once linked Asia and the Americas about 20,000 years ago. • Scientists use a process called carbon dating to measure the age of various artifacts.

What is a Native American? • Terms: • Native: a person born in a specific area. • American: Belonging to the Americas
Who came to the Americas, and when? • Europeans came to the Americas around 1492CE. • Native Americans crossed the land bridge from Asia into the Americas 20,000 years ago. • Vocab word: migrate/ migration – movement of people from one area to another • Why do you think these Native people migrated?
Ice Age • The Ice Age, which began about 100,000 years ago, caused a lot of the water from the oceans to freeze into glaciers (sheets of ice). • This made the oceans lower, exposing the land bridge, known as Beringia, running from Siberia to what is now Alaska. • This area now lies beneath the Bering Strait (a strait is a narrow body of water that connects two larger ones)
Land Bridge • A large number of people crossed this land bridge and spread out across the Americas in search of food. • Around 15,000 years ago, the ice age began to end. • Over several thousand years, the glaciers melted and oceans levels rose. • The rising oceans covered the land bridge.
Nomads • Early Americans were referred to nomads (people who moved from place to place to find food). • Around 10,000 years ago, people in what is now Mexico began farming crops such as maize (type of corn), pumpkins, beans, and squash. • Farming offered a stable source of food, which meant people did not have to move constantly.
Why do people migrate? • Where do you migrate to? • Why do you migrate to those places? • Why do you think Native Americans came to America?
Hunting • The first Americans were hunters • They hunted huge mammals, including bison, mastodons and mammoths Mammoth: extinct; extremely large and could feed a group for months Bison(also called buffalo) Mastodon: also extinct
Change from hunting to farming Agriculture – the science or practice of farming • Poll: What is easier, hunting or farming?
Farming overtakes hunting • SOME (not all) groups of Native Americans began to farm. • Farming was much easier and more reliable than hunting. • They planted seeds and waited for crops to grow. • They had to stay in one place to wait for their crops, so those who farmed became sedentary rather than nomadic.
Farming’s effects • Population increases due to increased amount of food and health • Because people weren’t using as much time hunting food they had time to do other things like develop governments, religions, technology and new ideas. • Because of this, GROUPS THAT FARMED TENDED TO BECOME THE MOST ADVANCED, whereas those who hunted tended to be less advanced (in terms of technology, political system, social organization.)
Culture • Each group, or tribe, of Native Americans had its own culture (shared traditions and behaviors). • What type of cultures do you have? Do they differ in different settings (example: home, school, activities) • How might the culture of a group that farms differ from a group that hunts? Think/pair/share
Closure • Write three examples of a nomad • Come up with three reasons why someone would move from place to place. • Why is farming better than hunting? Why benefits did farmers have that hunters did not?
