  • d. He had brothers, Thorvald and Thorstein, and a half-sister, Freydis. In the year 999 BCE, Ericsson sailed to Norway to visit King Olaf Trygvson. On his way the ship was blown off course and he landed on one of the Hebrides islands. Continuing poor weather made it impossible for him to leave so he spent the summer on the island.
  • . She gave birth to his son and as his departure date drew near, she asked that he take her with him. He refused, citing her family connections. Thorgunna had a reputation for being able to predict the future, and vowed that even though Leif was leaving them, one day she and their son would journey to find him and the experience would not be a good one.

  • What is known for certain is that Leif and the boy eventually found each other and the young man was recognized as his son.
  • Nevertheless, Leif left the island and got to Norway by the fall. King Olaf welcomed him to his court and asked if Leif had plans for a voyage to Greenland. The king had recently been converted to Christianity and wanted Leif to proclaim Christianity to the Norse settlers living in Greenland, including his parents. He returned to Greenland, and as the king wished, spread the message of Christianity. Leif’s mother, Thjodhild, quickly adopted the new religion, but his father, Eric, was reluctant to give up his pagan beliefs. Only when Thjodhild refused to live with
  • him as man and wife, did Eric the Red finally convert to Christianity.
  • Leif Eiriksson’s exploration and discovery of America was inspired by the accidental voyage of Bjarni Herjulfson.
  • As a skilled sailor and trader, Herjulfson had devoted himself to going on trading voyages from Iceland every other year
  • In 1002 BCE, Leif Eiriksson decided to explore the unknown lands discovered by Herjulfson while on the quest for his father.
  • Leif bought a ship from Bjarni and gathered a crew of thirty-five men.
  • Eric, his father, was approached about being the expedition leader. A fall from a horse prior to embarking convinced Eric that he would be unlucky on the voyage and that he was too old to set off on another adventure. Leif himself took command and the ship and crew departed.
  • The first country Leif encountered was the last one Herjulfson had seen. It was barren, with glacier-topped mountains and vast stretches of rock-covered ground
  • Initiating the practice of naming the lands he found after their geological and physical traits, he called this area Helluland, or “land of flat rocks.” (Labrador)
  • The second country Leif sailed to was level and wooded, with deep white beaches and a sloping shoreline. He called this place Markland (Newfoundland) or “forest land.” Leaving there, he sailed northeast. He found an island north of the mainland. He and his crew sailed the channel between the island and mainland and steered west. When they found land they went ashore, discovering a small river that flowed to the sea. They returned, took the ship up the river to a lake where they decided to build houses, and stayed through the winter.
  • The area had salmon in the river and lake; the winter was mild and almost frost-free, and the grass did not wither during the cold season.
  • The hours of daylight and nighttime were more equally divided than in either Iceland or Greenland
  • Leif divided his crew in half, determined to explore the area. Half would stay in camp while the other half went as a group to investigate the surroundings. The exploration crew was to go no further than the distance they could travel in order to return to camp by nightfall.

Henry Hudson - Facts & Summary - HISTORY.com - 0 views

  • wice being turned back by ice, Hudson embarked on a third voyage–this time on behalf of the Dutch East India Company–in 1609. This time, he chose to continue east by a more southern route, drawn by reports of a possible channel across the North American continent to the Pacific. After navigating the Atlantic coast, Hudson’s ships sailed up a great river (which would later bear his name) but turned back when they determined it was not the channel they sought. On a fourth and final voyage, undertaken for England in 1610-11, Hudson spent months drifting through the vast Hudson Bay and eventually fell victim to a mutiny by his crew. Hudson’s discoveries laid the groundwork for Dutch colonization of the Hudson River region, as well as English land claims in Canada.

Christopher Columbus: Voyages to the New World | Infoplease.com - 0 views

  • On Aug. 3, 1492, Columbus sailed from Palos, Spain, with three small ships, the Santa María, commanded by Columbus himself, the Pinta under Martín Pinzón, and the Niña under Vicente Yáñez Pinzón. After halting at the Canary Islands, he sailed due west from Sept. 6 until Oct. 7, when he changed his course to the southwest. On Oct. 10 a small mutiny was quelled, and on Oct. 12 he landed on a small island (Watling Island; see San Salvador) in the Bahamas. He took possession for Spain and, with impressed natives aboard, discovered other islands in the neighborhood. On Oct. 27 he sighted Cuba and on Dec. 5 reached Hispaniola.

The First Voyage of Christopher Columbus (1492-1493) - 0 views

  • On December 25, the Santa María ran aground and had to be abandoned. Columbus himself took over as captain of the Niña, as the Pinta had become separated from the other two ships. Negotiating with the local chieftain Guacanagari, Columbus arranged to leave 39 of his men behind in a small settlement, named La Navidad.
  • Leaving Cuba, Columbus made landfall on the Island of Hispaniola on December 5. The natives called it Haití, but Columbus renamed it La Española, a name which was later changed to Hispaniola when Latin texts were written about the discovery.

  • Columbus named the island San Salvador, although he remarked in his journal that the natives referred to it as Guanahani. There is some debate over which island was Columbus’ first stop; most experts believe it to be San Salvador, Samana Cay, Plana Cays or Grand Turk Island.

Neptune -- Britannica School - 0 views

  • The planet that Voyager uncovered is a stormy, windswept world with a vivid blue hue. Its highly active atmosphere is surprising, since it receives so little sunlight to power its weather systems. Like the other giant outer planets, Neptune has no solid surface. It also has a system of rings and more than a dozen moons.
    • Diego Hinojosa
       
      Neptune is a planet that has a lot of blue. It's atmosphere and also surface is not solid. It also has rings and like 12 moons.
  • Neptune is the smallest of the four giant outer planets. The diameter at its equator is about 30,775 miles (49,528 kilometers), as measured at a level of the atmosphere where the pressure is 1 bar (the pressure at sea level on Earth). This makes it slightly smaller than Uranus but nearly four times as big as Earth. Neptune’s mass is about 1.2 times greater than Uranus’, however, and more than 17 times greater than Earth’s. It is the third most massive planet in the solar system, after Jupiter and Saturn. Like the other outer planets, Neptune has a low density—only about 1.6 times the density of water. However, it is the densest of the four, being roughly 25 percent denser than Uranus.

Samuel de Champlain - Biography - Diplomat, Explorer - Biography.com - 0 views

  • Samuel de Champlain was a French explorer and cartographer best known for establishing and governing the settlements of New France and the city of Quebec.
  • French explorer Samuel de Champlain was born in 1574 in Brouage, France. He began exploring North America in 1603, establishing the city of Quebec in the northern colony of New France, and mapping the Atlantic coast and the Great Lakes, before settling into an administrative role as the de facto governor of New France in 1620. He died on December 25, 1635, in Quebec.
  • Samuel de Champlain was born in 1574 (according to his baptismal certificate, which was discovered in 2012), in Brouage, a small port town in the province of Saintonge, on the western coast of France. Although Champlain wrote extensively of his voyages and later life, little is known of his childhood. He was likely born a Protestant, but converted to Catholicism as a young adult.

Jupiter - 0 views

  • Jupiter has a very faint ring system, but is totally invisible from the Earth. (The rings were discovered in 1979 by Voyager 1.) The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic.

How birds fly | Sciencelearn Hub - 0 views

  • Birds have many physical features, besides wings, that work together to enable them to fly. They need lightweight, streamlined, rigid structures for flight. The four forces of flight – weight, lift, drag and thrust – affect the flight of birds.
  • Flying birds have: lightweight, smooth feathers – this reduces the forces of weight and drag a beak, instead of heavy, bony jaws and teeth – this reduces the force of weight an enlarged breastbone called a sternum for flight muscle attachment – this helps with the force of thrust light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight a rigid skeleton to provide firm attachments for powerful flight muscles – this helps with the force of thrust a streamlined body – this helps reduce the force of drag wings – these enable the force of lift.
  • WingsThe shape of a bird’s wing is important for producing lift. The increased speed over a curved, larger wing area creates a longer path of air. This means the air is moving more quickly over the top surface of the wing, reducing air pressure on the top of the wing and creating lift. Also, the angle of the wing (tilted) deflects air downwards, causing a reaction force in the opposite direction and creating lift.Larger wings produce greater lift than smaller wings. So smaller-winged birds (and planes) need to fly faster to maintain the same lift as those with larger wings.Wing loading tells you how fast a bird or plane must fly to be able to maintain lift: wing loading = weight/wing area (kilograms per square metre).A smaller wing loading number means the bird/plane can fly more slowly while still maintaining lift and is more manoeuvrable.

  • GlidingWhen a bird is gliding, it doesn’t have to do any work. The wings are held out to the side of the body and do not flap. As the wings move through the air, they are held at a slight angle, which deflects the air downwards and causes a reaction in the opposite direction, which is lift. But there is also drag (air resistance) on the bird’s body, so every now and then, the bird has to tilt forward and go into a slight dive so that it can maintain forward speed.
  • SoaringSoaring flight is a special kind of glide in which the bird flies in a rising air current (called a thermal). Because the air is rising, the bird can maintain its height relative to the ground. The albatross uses this type of soaring to support its multi-year voyages at sea.
  • FlappingBirds’ wings flap with an up-and-down motion. This propels them forward. The entire wingspan has to be at the right angle of attack, which means the wings have to twist (and do so automatically) with each downward stroke to keep aligned with the direction of travel.
  • Birds obtain thrust by using their strong muscles and flapping their wings. Some birds may use gravity (for example, jumping from a tree) to give them forward thrust for flight. Others may use a running take-off from the ground.
  • Different birds have different adaptive features to meet their flight needs: Some birds are small and can manipulate their wings and tail to manoeuvre easily, such as the fantail (pīwakawaka). The hawk, with its large wingspan, is capable of speed and soaring. Gannets and seabirds are streamlined to dive at high speeds into the ocean for fish. Godwits, although small, are equipped to fly long distances.

      birds have some chacteristics that help them fly, birds are light weighted they have light feathers insted of heavy ones that add more weight to their bodys, they also have a beak insted of jaws that also add weight to their boddys, thay have hollow bones in their body that means that the bone has nothing inside it

      birds get ready to fly by flapping their wings, some birds use "gravity" to take of some run and they jump just like an airplane and others jump from a tree and then start flapping their winds
