Year: 1986 Language: English Author: Michael Pollard Genre: Textbook Publisher: Schoolhouse Edition: 1 ISBN: 0-8086-1043-0 Format: PDF Quality: Scanned pages + text layer Pages count: 50 Description: When the first sailors set out to explore the world, they sailed along the coast. They felt safe because they were never far from land. Later, when they sailed off across the ocean, these first sailors soon lost sight of the land. They might sail for days or even weeks only seeing the sea and the sky. These first explorers had nothing to help them find their way. Some animals find their way over great distances without any help at all. They use their instinct, which is a natural way of doing things that all animals have. When birds fly to warmer countries in the winter months, this is called migration. Caribou, or reindeer, also migrate southwards from the Arctic in search of food. Even some butterflies fly hundreds of miles to lay their eggs. People do not have the same instinct as animals. Over thousands of years we have learned how to navigate, or find our way, with maps and instruments. Three things are necessary to navigate well. First, you must know where you are. Then, you must know the place or position you want to reach. You must also know the direction to take in order to get there. This book tells the story of how people learned to navigate. We are going to start like the first explorers. These sailors had nothing to help them. They had, however, seen that the sun rose on one side of the sky every morning. It moved across the earth and set on the other side in the evening. Could they use the sun to point them in the right direction?
