Exploration Stations Name: Station 1: Reasons for and Methods of Exploration 1. Explain the concept of “God, gold, and glory!” as it pertains to explorers. 2. Rank the items explorers used to navigate the seas using the handouts AND the textbook, page 530. Use your own words. Ranking Item Brief Description Reason you ranked it here 1 (Best) Magnetic compass A floating magnetized needle that always points north south; device had existed in China for centuries before it was adapted by sailors for use at sea Can determine location from anywhere at anytime 2 Astrolabe This scientific instrument had a fixed “plate” and a rotating “rete” . The plate was a map of the sky and the rete stimulated the daily movement of the earth in relation to the stars Can only determine location if the stars are out 3 Chip Log A line containing knots at regular intervals and weighted to drag in the water was let out over the stern as the ship was underway. A seaman would count the number of knots that went out over a specific period of time and the ship's speed could then be calculated Determining speed is an important part of determining how long a voyage is 4 Hourglass The hourglass was the most common means for counting tie at sea. The hourglass was used to measure the day at sea which was divided into six four-hour watches Time is important for keeping a log for how long a voyage is 5 The Quadrant Device A simple device used by early explorers from medieval times on for measuring altitude and latitude was the quadrant This tool isn t worse than the sextant 6 (Worst) sextant The sextant provided mariners with a more accurate means of determining the angle between the horizon and the Sun, moon, or stars in order to calculate latitude This tool just seems completely useless Station 2: Explorer Timeline 1.
