1. The First Americans
The first Americans needed to adapt to their environment in order to survive.
The cultures developed by these first Americans reflected the environments in which they lived.

2. I. Human Migration to the Americas
Widely believed that the first Americans arrived during the last ice age (15,000-30,000 years ago)
Glaciers locked up water from oceans and caused sea levels to fall; therefore, land that had been under water was uncovered
A land bridge (called Beringia) joining Siberia in Asia to Alaska in North America was revealed
Scientists believe that the first Americans followed the herds of animals that they hunted across this land bridge from Asia into North America
The continual search for better hunting grounds led these early Americans across North America, Central America, and South America

3. Studying the First Americans
Archaeologists study artifacts to learn about past cultures
Types of artifacts can include weapons, tools, pottery, tombstones, baskets, and bones
By studying artifacts, archaeologists can learn much about the people who made them
After examining artifacts, archaeologists form theories about past cultures (entire way of life that a people has developed)

4. North American Culture Areas
A culture area is a region in which people share a similar way of life
There were 10 major culture areas in North America
Within each culture area there were many different tribes (group of villages that share common customs, languages, and rituals)
The people living in these culture areas needed to adapt to their environment to survive
Examples of North American culture areas were the Arctic, Southwest, Great Plains, and Eastern Woodlands

5. A. The Arctic Very cold, snowy, treeless, icy plains
Native Americans, like the Inuits, used their limited resources to survive
Collected driftwood to make tools and shelter
Built igloos out of snow and ice
Paddled kayaks into the sea to hunt for seals, whales and walruses or moved inland and hunted caribou or fished
Religious beliefs reflected their close ties to the natural world. They believed each animal had a spirit and they offered gifts to animals they wished to catch and sang songs of thanks after successful hunts.

6. B. The Southwest Hot, dry desert
Early cultures like the Anasazis and Hohokams developed vast irrigation systems in order to farm
Used stone and adobe to build large, multi-storied houses that could shelter hundreds of families
Descendents of the Anasazis (the Pueblos) also built adobe houses and farmed
Religious beliefs of the Pueblos often reflected the importance of farming; held ceremonies to ensure rainfall and good crops
Pueblos traced their family lines through their mothers, Pueblo wives owned most of the family property, and after marrying, a man went to live with his wife’s family

7. C. The Great Plains
Vast grasslands that stretched from the Rocky Mountains to the Mississippi River
People made their homes of sod, or built tepees using the hides of buffalo
Women used animal bones to make hoes which they used for farming corn, beans, squash and sunflowers
Men hunted animals, including buffalo, antelope, deer, elk, and bighorn sheep
During the 1700s, they began to tame wild horses that had been introduced to North America by Europeans during the 1500s
Each village had a ruling council that included the best hunters

8. D. The Eastern Woodlands
Included the Northeastern part of present-day U.S. (from Atlantic Ocean to Mississippi River) and eastern parts of present-day Canada
Many trees, lakes, and rivers
Forested region had an abundance of plant and animal resources
Native Americans used trees to build longhouses or wigwams
Fished, hunted, and farmed for food
This culture area was home to two powerful groups of Native Americans: the Iroquois and Algonquins
