Navigation and Longitude Measures Degrees
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
Gnomon- the length of the suns shadow casted on a disk in the water
Astrolabe- a disk suspended by a small ring, has degrees and a ruler for measuring
Cross Staff- t shaped device held up to the eye.
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
Sextant- it had a telescope and an index mirror, but was very time consuming
Chronometers
Current Navigation Tools (Lesson 02.01) • What tool do we currently use to determine location (latitude and longitude)? Maps, or GPS
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 runs N&S Latitude runs E&W
Longitude measures degrees east or west of the prime meridian, latitude measures degrees north or south of the equator. • What are longitude and latitude measured 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? • What tool was used to do measure the depths of the ocean? • What are the 2 pieces of equipment used to collect bottom samples on the Challenger? • What was a newly invented piece of equipment used on the Challenger ship to get water samples
