Tools used to measure latitude (Lesson 02.01) (use the first resource in this lesson to help you)
Be able to list and describe the 3 main tools used to measure latitude in early navigation
Sextant- allowed users to determine their latitude to within a sea mile or two
The gnomon or sun-shadow disk- operated like a sundial, enabling the user to determine his latitude by the length of the sun's shadow cast on a disk floating level in water.
The Arabian kamal- a rectangular plate that one moved closer or farther from one's face until the distance between the North star and the horizon exactly corresponded to the plate's upper and lower edges. The distance the plate lay away from the face—measured by a string tied to the center of the plate and held at the other end to the tip of the nose—determined the latitude. cross staff
Tools used to measure longitude (Lesson 02.01) (use the first resource in this lesson to help you)
Be able to list and describe the 2 main tools used to measure longitude in early navigation
the chronometer- the sextant to figure longitude using the lunar-distance method
Current Navigation Tools (Lesson 02.01)
What tool do we currently use to determine location (latitude and longitude)?
the Global Positioning System,
Longitude and Latitude (Lesson 02.01)
Know the ways that longitude and latitude run (N to S or E to W) and what they measure
Longitude E to W - know how far east or west they were of the Prime Meridian
Latidude N to S - how far north or south they were from the equator
What are longitude and latitude measured in? they measure in degrees
Challenger Expedition (Lesson 02.02)—Best resource link to use = “Account of the Voyage of the Challenger”
Besides conducting sampling of the waters on its journey, what were the main findings from the Challenger voyage? found many new species, and provided collections for scores of biologists.
What tool was used to do measure the depths of the ocean?
