1 Chapter 1 Exploration

2 Objective for Today Evaluate the theories of how the earliest Americans migrated from Asia to the New World.

3 Theories of how people got to America
Land Bridge Theory Coastal Route Theory Pacific Crossing Theory Atlantic Crossing Theory

4 Land Bridge Theory Approximately 100,000 years ago
Earth began to cool gradually - glaciation Periods of glaciation – Ice Ages Water froze into sheets of glaciers Ocean level dropped 300 feet & showed the floor of the Bering Sea Connected Asia with Alaska – Beringia

5 Beringia 1,000 miles wide 15,000 years ago – People from Asia came following food. Nomads & hunters Continued till the ice melted

6 Coastal Route Theory Crossed from NE Asia in boats Skirting the shore
Land occasionally to hunt Would have reached South America quicker than any land route

7 Pacific Crossing Theory
Migrants from SE Asia went south to Australia & across the Pacific Ocean, hopping from island to island until they reached South America.

8 Atlantic Crossing Theory
From Southwest Europe (southern France & Spain) Hugging the edge of the glaciers of the North Atlantic Sailed from Iceland & Greenland down to North America

9 Using the small map on page 19, outline the four routes on your own map.

10 Day 1 REVIEW ACTIVITY Which theory do you think was the best route & why? Must write one paragraph explaining your answer.

11 Objective for Today Identify & describe the causes of exploration.

12 Causes of Exploration Crusades Renaissance & Protestant Reformation New Technology

13 The Crusades – Holy Wars
Purpose: Christians wanted to get the Holy Land back from the Muslims Essential Details Western Europeans discover Asian food, spices, & clothing. Want to trade between Europe & Asia Trading was slow & expensive over land Went looking for a sea route – explorers like Columbus Columbus discovers America while trying to find a way to India So what? What is important to understand about this?

14 Renaissance Time of great cultural developments & societal changes in Europe. People began to read the Bible & other early church writing with a critical eye. Wanted to reform the church & get rid of any religious practice not in the Bible.

15 Protestant Reformation
Began with Martin Luther Movement to reform the Catholic Church Church leaders were not happy Leaders of the reform movement broke away from the Catholic Church & formed their own churches Many went to the New World so they could worship freely.

16 So what is the relationship between the Renaissance & Reformation?

17 New Technology Astrolabe
Invented by the ancient Greeks & made better by Arab navigators. Used the position of the sun to determine directions, latitude & local time.

18 New Technology Compass Invented in China
Reliably showed the direction of magnetic north.

19 New Technology Caravel Portuguese ship
Small ship able to carry 130 tons of cargo. Needed little water to sail. Allowed explorers to go in shallow water & beach ships to make repairs.

20 Portuguese Exploration
1419 – Prince Henry (Henry the Navigator) Set up a center for research & invited explorers to come & map out voyages there. 1420 – began mapping Africa’s west coast

21 Portuguese Exploration
1488 – Bartholomew Dias reached the tip of Africa 1497 – Vasco da Gama Rounded Africa’s tip heading to India Landed on India’s Southwest coast 1st water route to Asia found!

22 Portuguese Exploration

23 Review Activity: Causes of Exploration Foldable
Fold your paper like a hotdog. Make two slits, creating 3 different sections. Create a foldable with the outside headings listed below. Crusades Renaissance & Reformation New Technology

24 Causes of Exploration Foldable
Inside: Include a one paragraph summary explaining how this event or thing (Crusades, Renaissance & Reformation, & New Technology) caused exploration. A paragraph is considered 4-5 complete sentences. Include a picture to illustrate the event or thing.

25 Preview Activity Answer these questions if you can:
Who was the first explorer (s) to find the Americas? Who was America named after?

26 Objectives Identify the first major explorers of the Americas & the significance of their exploration. Judge the success of Columbus’ journey & its impact on the New World inhabitants.

27 Vikings Around 1000 A.D. they explored the coast of Labrador
They tried to set up a life there but it didn’t work cause they were outnumbered by hostile Native Americans.
