Columbian exchange file

  1. 1. The Columbian Exchange<br />
  2. 2. Here Be Dragons<br /><ul><li>In 1492 no one really knew what the world looked like.
  3. 3. Exploration was a big adventure. Like going into outer space today. Sailors really did not know what they would find, or even if they would return home again.
  4. 4. Areas on maps were known as Terra Incognita – “unknown territories”</li></ul>Some maps even said “HERE BE DRAGONS” in some areas, because no one really knew what they would find there.<br /><ul><li>Old maps showed the world to be much smaller than it actually is.
  5. 5. Columbus studied Ptolemy's map and thought that he could find a quicker way to the East by sailing West. </li></ul>See Ptolemy's Map<br />
  6. 6. Navigation<br /><ul><li>Columbus used dead reckoning navigation.
  7. 7. Using a magnetic compass (always points North), a known starting point ( a port or known land mark), calculations for distance time and speed, measurements were taken and charted on a chart with pin-pricks. The pin-pricks were joined together to form the course taken. The last pin-prick charted was the starting point for the next day’s course.
  8. 8. Columbus never used celestial navigation , as his helmsmen, who steered the ship with a tiller ,were below decks , and could not see the stars!!!!
  9. 9. Columbus was the first captain to keep a detailed log (just like in star trek) of his voyages, and this is how we know how he navigated his ships in uncharted waters.</li></ul>Make your own compass <br />
  10. 10. The Ships<br /><ul><li>The Nina, The Pinta, and the Santa Maria were the names of the 3 ships that voyaged with Columbus.
  11. 11. The Santa Maria Columbus’ favorite, it was the Flag ship. It was a Nao - a tub, big and awkward, and couldn’t go near the coastline. It was slow but could carry a lot of cargo, and stand up to heavy storms.
  12. 12. The Pinta was a caravel ; it was smaller, lighter and faster than the Santa Maria.
  13. 13. The Nina was also a caravel, but was the smallest of the ships that sailed with Columbus.
  14. 14. There were 87 crewmen split between the three ships.</li></ul>ships<br />LearnMore about <br />
  15. 15. The Exchange <br /><ul><li>The “Columbian Exchange” refers to the interactions of the people of the “Old World” with people from the “New World” during and after the age of exploration.
  16. 16. The Columbian Exchange includes Europe, Asia, Africa, and the Americas.
  17. 17. So what exactly was exchanged from one culture to the other:</li></ul>Food<br />Clothing<br />Animals<br />African Slaves<br />Precious Metals <br />Ideas<br />Diseases<br />(Imagine – without the Columbian Exchange we wouldn’t have any chocolate!!!!!!)<br />
