Did You Know?The speed of sound in water is 1,435 m/sec
- nearly five times faster than the speed of sound in air.
This is why Whale songs can be heard from so far away.
Objective: Begin learning about history of marine science and some of the first marine explorers.
Agenda:Organize notebooksGo over Unit 2 Learning GoalsHistory of Exploration Notes
pg. 25
HomeworkNone
Voyages of DiscoveryExplorers and NavigatorsThe first vessels-3000 B.C.
Merchants 2000 B.C.
Fall of the Roman Empire
5000 B.C to 800 A.DEgyptians- made the first sailboats
Phoenicians- made the first trade routes (Mediterranean)
Polynesians- made primitive maps and were the first to have long distance open ocean voyages.
Greeks- Major advancements in navigationPytheas- mapped out latitude using the North StarEratosthenes- calculated Earth’s circumference.
800 A.D to 1400 A.DVikings- Improved sailboats
Bigger sailsOarsmen if no windFlat-bottom boats (get closer to land)
Sea exploration was only done by Vikings
This lasted from about 800-1100 A.D. (the middle of the dark ages)
Major Viking discoveries9th century: warming climate led to melting N.
Atlantic ice, this allowed more Viking voyages through previously frozen area.
Discoveries:Iceland (mild climate)Greenland (frozen land) North America (Newfoundland Canada) led by Leif Eriksson
Leif Eriksson day is Oct. 9th
Middle Ages = Dark AgesIn EuropeAny thoughts on why they were called the
dark ages?
Knowledge of geography and science entered an intellectual “darkness” there was also, poor communication and lack of education.
Meanwhile… In China…During the European “Dark Ages” other parts
of the world, were making intellectual progress.
In 1125 the magnetic compass was invented and being used by the Chinese sailors.

might have a pop quiz!
The End of the Dark AgesBartholomeu Dias
A Portuguese navigator1487-Sailed around the tip of Africa, which he called: "Cape of Storms" (Cabo das Tormentas). Later named the Cape of Good Hope
Christopher Columbus 1492 went to sea to find a new route to India for trade, he headed west and crossed the Atlantic and landed in the Bahamas
Later he reached South and Central America
Later ExpeditionsJohn Cabot- 1497 left England and sailed to
what is now Delaware.Vasco Nunez de Balboa – 1500s crossed the
Isthmus of Panama, first to see the East coast of the Pacific
Amerigo Vespucci explored 9600 km of coastline from North to South AmericaMapmakers in Europe named the Americas after him
First to recognize S. America as it’s own continent
Later Expeditions Cont. Ferdinand Magellan, a Portuguese
navigator , was the first to attempt to circumnavigate the earth
Francis Drake- 1577 second successful circumnavigation of the world, his purpose was to raid Spanish ships for treasure.

boiled? Just spin the egg. If it wobbles, it’s raw. If it spins easily, it’s hard boiled. A fresh egg will sink in water, a stale one will float.

Hapalochlaena species can inject enough venom in one bite to kill several adult humans. They can adopt a two-tentacles "walk" that frees up their six remaining limbs and makes them look like an armed vehicle.

Titanic Conclusion don’t need to write
Theories of why the ship sank could not be proven because for 73 years the ship could not be located
In 1985 the ship was found with the help of sonar and an underwater robot
With modern technology scientists concluded that the ship sank due to water flowing over the bulkheads and causing the ship to lose buoyancy.
