It flew back to the Faroe Islands. A day after this he let the second bird go. This flew out of sight but came back to rest on the ship. Sometime after that, he let the third bird go. It headed straight for Iceland so Raven-Floki followed it and arrived there safely.

compass stars currents birds
1. Vikings used to prefer to sail following the coastline so they could check that they were on the correct route.
2. Vikings used birds, and natural features like mountains, to direct their ships.
WM: Really? How cleaver! Did everybody use simple maps?
DS: No. I'm afraid not. It was difficult to have a map for sailing across open sea then. We know the Vikings from Norway had no written maps when they sailed across the North Sea.

The First Voyage. Following the war，Cook was given the mission to lead an expedition to observe the rare passage of Venus across the face of the sun in order to determine the accurate distance between the earth and sun.He set sail from England ind at Tahiti where he did the observation.He proceeded to the West Indies and across the Indian Ocean to the Cape of Good Hope at the southern tip of Africa.

3. Read the chart below and fill in your plans of action to deal with them.
What would you do Plan of action if :
You were far from land and a storm arose.
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.
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.
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.
The handle of the spoon points to the south, while the other side points to the north. When the Sinan is in the still, the handle of the spoon points to the south because of influence of the terrestrial magnetism (地磁).
4. Which ones do you think are still used today?
Sea charts are still used today.
Read and answer these questions.
1. Where do these materials come from? 2. What did the early navigator use to
sextant
The sextant is a navigational instrument for measuring the angle between the horizon and some object in the sky. First a sailor looks at the horizon through an eyepiece. At the same time he can see light from the sun or a star reflected off a small mirror on top of the instrument, onto a second mirror and into the eyepiece.

The four basic instruments for navigation: Sinan, Inch Astrolabe, Sextant and nautical map.
Sinan, the ancient Chinese compass.
It was invented by Zhang Heng in the Han dynasty. It is made up of a bronze foundation (青铜地盘) and magnetic spoon(磁勺) which is made of natural magnet, positioned right in the central of the foundation.

3. Can you identify these early navigational instruments seamen used and explain how they are used?
1) compass ( in ancient China) 2) astrolabe 3) sextant 4) sea / nautical / marine chart
It has 17 stars listed as well as a map of the sky overhead (for 37 degrees) and the ecliptic (黄道). The time of day or night is on the outside astrolabe edge with noon at the top of the Astrolabe and midnight at the bottom. It comes with a carrying chain, a pouch, and a book on its use. The reverse side has a sight for measuring the elevations of the heavenly bodies.
Discuss
1. How do you think seamen found their way before modern accurate methods of navigation were invented? Kept close to the shore, used nature such as the sun, wind, birds, tide, etc, to help them, and used some of the instruments including a compass, astrolabe, etc.
2. Suppose you were a sea captain aiming to sail round Africa. Discuss in groups:
1) What skills would you seek in your sailors?
2) What problems would you anticipate for this journey?
2. Which do you think was easier to work out: latitude or longitude? Latitude, because it was used to measure how far you had traveled from land on a straight line. It was discovered a long time before longitude.
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
2) Why are speed and time important in working out the longitude of a ship?
the sextant mean the same thing?
