Stay far enough south of the Faroes so that their steep mountains are just halfway up the horizon. Keep south of Iceland so that you cannot see land but just coastal birds. Follow this route and you should reach Greenland.Use the information from the listening to explain these sailing strategies.Vikings used to prefer to sail following the coastline so they could check that they were on the correct route.
Vikings used birds, and natural features like mountains, to direct their ships.Sayings What do they mean?1.“If you can read the ocean, you will never be lost.”Study the waves so that you can read what will happen in the weather or when land is close.What do they mean?2. “Watch for when the sun grows.”The position of the morning sun on the horizon can help you check your course.What do they mean?3. “the stars are the yes of Heaven” “the stars can give you information about your position and can help you “see” where you are.”What do they mean?4. “When the bird flies out to sea, the sea will grow calm.” Birds do not fly out to sea if a storm is coming so a bird flying away from the shore means good weather.
