In pairs discuss these questions: 1 What is a navigator?
A navigator explores new routes across the sea. 2 What is the difference between a navigator and an explorer?
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.
2 Which do you think was easier to work out: latitude or longitude?
Latitude, because it was used to measure how far you had travelled from land on a straight line. It was discovered a long time before longitude.
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.
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.
