navigator sea
nautical instruments
find new islands or continents
A navigator is sb. who finds the position and plots the course of a ship by using maps and nautical instruments.
explorer land
compass and landmarks
find new places within an already identified island or continent
A explorer is sb. who travels into or through a place in order to learn about it.
Very often navigators are also explorers.
Can you identify these early navigators\explorers?
Zheng He Marco Polo
James Cook Christopher Columbus
Zheng He, the most famous Chinese na
vigator, lived from 1371 to 1433 and mad
e seven voyages around the South China
Sea, visiting more than thirty countries.
The people there gave him a warm welco
me. And he not only spread Chinese cult
ure, but also developed many trade lin
ks with the other countries.
In the years between 1405 and 1433, s
even large treasure fleets sailed westwar
ds on voyages of trade and exploration.
Under the command of Zheng He, the fle
ets set sail from the South China Sea acr
oss the Indian Ocean to the Red Sea, and
then traveled further south, discovering t
he eastern coast of Africa.
He renewed relations with the
Kingdoms of the East African coast.
One African king sent the Ming
emperor a royal present: two giraffes.
Marco Polo was the only person to pro
vide information about China to the ou
tside world. His journey around Asia la
sted 24 years. He reached further than
any of his predecessors, travelling beyo
nd Mongolia and into China. Finally he
wrote his adventures down and his boo
k was published and became a best-sell
er.
About 700 years ago a young trader from
Italy took a long trip to Cathay. Cathay is
known as China today. He went with his father
and uncle, who had traveled there once before.
They stayed in China for about two decades.
The young man's name was Marco Polo. He
was liked by the leader in China at the time.
He knew four languages and traveled a
round the kingdom as the leader. When
Marco Polo returned to Italy, he dictated
his story to a writer. He told of the Chines
e postal system, paper money, and the use
of coal as fuel.
James Cook
James Cook (1728-1779) was the greatest Bri
tain navigator. Cook enlisted in the Royal Navy
in 1755. In 1768 he was promoted and sent to th
e Pacific where he surveyed Tahiti, New Zealan
d, and Australia. On his famous second expediti
on (1772-1775) he explored Antarctica. In 1776
he undertook his third and final voyage in whic
h he explored
the West Coast of North America and trie
d to locate a passage between the Atlantic
and Pacific oceans.
On this voyage he discovered the Hawai
ian Islands, and sailed up the coast of Nor
th America through the Bering Straits to t
he Arctic Ocean. On his return he was kill
ed by Hawaiian islanders.
1.Can you identify these early navigational instruments seamen used?
2. How do they work?
compasscompass
a bearing circle
方位圆
the first instrument to measure the sun’s position and the sun’s shadow
astrolabe
The astrolabe measures the height and
position of the sun. If you can measure
this accurately, a sailor can tell how
many degrees the boat is from the
North Pole. From this he can tell
where the boat is in the ocean.

sextant
The sextant is a navigational instrumen
t for measuring the angle between the h
orizon and some object in the sky. First
a sailor looks at the horizon through an
eyepiece( 接目镜) . At the same time h
e can see light from the sun or a star ref
lected off a small mirror on top of the i
nstrument, onto a second mirror and in
to the eyepiece.

The navigator can then see two images,
the horizon and the sun side by side. He
can then measure the angle between
them on a scale at the bottom of the
instrument. The scale goes from 0 to
120 degrees. An earlier instrument,
called a quadrant, measured in angle in
the same way but it could only measure
angles from 0 to 90 degrees.

nautical chartnautical chart
Nautical charts are maps of the depth of the sea and the currents of the oceans. They provide modern sailors with routes through the seas, rather like roads through the countryside. The information began to be collected in the nineteenth century and has continued to be updated ever since. These charts were not available to Captain Bligh or Zheng He.

What do you think was the first and most important way of exploration then?
Keeping alongside the coastline
Using celestial bodies
to plot the positionsto work out the latitude
a special cloud formation indicates there is land close by
Using wildlife
If seaweed was fresh and smelled strongly, the ship was close to land.
Sea birds could be used to show the way to land when it was nowhere to be seen.
Using the weather
To help identify the position of a stream or river when they were close to land.
To direct their sailing
Using the sea
carry ships to their destination

Comprehending
1. Read the passage and answer the following questions.
1) What is the use of a bearing circle, astrolabe, quadrant or sextant? ( ) What is the use of a compass? ( )
A. To set the course of the ship B. To measure the position of the ship C. To measure the speed of the ship D. To tell the time
AB
2) Why are speed and time important in working out the longitude of a ship?Speed and time are important in finding out the longitude of a ship because the earth moves fifteen degrees westwards every hour. If you know your direction, speed and time, you can work out the approximate longitude or change in your position in relation to the stars.

If you know your direction, speed and time, you can work out the approximate longitude or change in your position in relation to the stars.
3) Why is the position of the sun and various
stars useful for working out latitude?
The position of the sun and stars are
useful for working out latitude because
they are fixed points in the sky and their
movements in relation to the earth are
already known. So they can be used to
measure a ship's position.

1. What skills would you seek in your sailors?
The sailors would need to be excellent navigators, able to cope with both hot and cold weather, experienced in sailing through very bad weather and able to co-operate in a team.
2. What problems would you anticipate for this journey?
I would anticipate very hot weather (around the equator), cold weather (around Cape of Good Hope), very stormy seas (around the Cape), and problems with food and water, etc.
What would you do if you came across the following problems during your voyage?
What would you do if: Plan of action
You were far from land and a storm arose.
You knew your latitude but didn’t know your longitude.
You were blown off-course.
You were offshore but you needed more food and water.
You wanted to keep a straight course.
You were lost with no land in sight.
wait till the storm is over, and then find your new position and return to your original course
use knots to find your speed and work out your approximate longitude
use the compass and the astrolabe, quadrant or sextant to find out your position, return to your former course.
follow nesting birds to shore; look for special cloud formations or fog over streams to find land
use a compassmeasure your position using the sun or stars; look for sea birds, cloud formations, fog or seaweed to show that land is nearby
