  1. The Titanic, Revisited

  2. What REALLY Happened? • In 1985, a robot vehicle called the Argo located the wreck of The Titanic on the ocean floor, in the North Atlantic (564 km SE of Newfoundland) • This study was a combined effort by a U.S.A/French research team • At that time, it was still thought that the iceberg collision caused a huge gash in the hull • In 1996, sonar was used to examine a part of the ships bow that was buried in sediments

  3. The Titanic • The Sonar imagery discovered 6 narrow openings along the right side of the hull • Based on this new evidence-it was discovered that the iceberg tore the hull not in one place, but in SEVERAL • This force of water broke steel support beams that supported the steel covering of the ship • The air filled compartments in the hull had watertight walls, or bulkheads • Water rushed in over the bulkheads, and 6 out of 16 compartments filled, in succession • This added weight was too much for the buoyant force!

  4. Early Explorers! Who were the early explorers and navigators of the oceans? Why did they do it?

  5. Why travel the oceans? • Oceans have been used for travel since early times • It was cheaper to transport by sea than by land! • Since early times, humans have settled in areas along the sea itself or waterways leading to the sea • The earliest watercraft were log rafts and canoes made from hollowed out trees – powered by humans!

  6. Ocean Explorers • The first sailing vessels were made around 3000 B.C. • This vessel was powered by wind and could travel much faster and much farther from shore • By using these ships, people became sea travelers, and the ocean became the “highway for trade” • But, Explorers kept searching for new, faster trade routes!! • Some even tried to circumnavigate (to sail completely around Earth)

  7. Class Activity! • I am going to put you into small groups for this assignment. • The task is for each group to take their assigned explorer and do some research – find out their: • Country of origin (where are they from) • When did they explore (dates)? • Lands explored • Contributions to ocean navigation • Any other info you wish to share with the class!

  8. Activity • Once we’re done, a spokesman (sorry…a spokesperson) will come up to the front of the room and explain to the class what they wrote about their explorer • Write legibly, because we will be compiling these to make a packet for the class to study from • Good luck and have fun! Now for the list of explorers…

  9. Ocean Explorers • The Phoenicians • The Vikings • Bartholomeu Dias • Christopher Columbus • John Cabot • Amerigo Vespucci • Vasco Nunez de Balboa • Ferdinand Magellan • Giovanni da Verrazano • Jacques Cartier • Henry Hudson
