EffEcts of tEchnology on Exploration 1. Navigation a. Astrolabe i.

This allowed explorer to measure the distance between the stars and the horizon.

ii.

It allowed explorers to calculate latitude or distance from the equator.

iii.

After leaving sigh of land they could sail back again and follow the land back to their original height on the globe.

iv.

Because of these maps, were accurate in height, but were really off in regards to width of continents and oceans.

Cross Staff

C. Sextant

i.

Did the same as the Astrolabe,

ii.

Allowed more accurate measurements because it was longer‌easier to use.

iii.

What if a shorter person was using it‌ or on a rocking boat.

iv.

Cheap and easy to make.


i. Again calculated latitude, but was easier to use and more accurate. D. Compass i. A magnetic needle that was placed in water that always pointed to magnetic north. ii. It gives you the direction you travelling. The first ones were bulky. Iii. It allowed you to sail further away from land and come back. v.

Once explorers had the compass and the cross staff they could travel and only get a little lost‌ it game them confidence.

E. Chronometer i. A watch that can operate on a boat. ii. Does not operate by a pendulum like a grandfather clock, but by a wind up coil. iii. even works in rough wavy conditions. vi. It allowed you to know the time in your country or destination and when comparing the time in your present location you could tell how many hours and minutes east or west you are. iv. This allowed to be very accurate in your sailing‌make more money!!!


iiv. This allowed better maps that did not look like dog barf!!! F. Radar i. Discovered in 1800’s, but not developed until 1940‘s for war purposes. ii. A ship or plane with radar can help with rescue operations 1. Exploring Antartica iii. It can tell you where land and other obstacles are Icebergs and reefs a. Wish the Titanic had radar 2. B ad weather a. Thunderstorms g. GPS i. Provides directions, location and time. ii. Shows explorers where to go accurately. iii. Satellite photos and GPS make accurate maps. 2. Ships a. Chinese Junk i. Sails could be raised or lowered by a pulley.


ii. Only one man neede to raise a sail. iii. Less crew needed iv. Less food for crew v. More money in trade vi. Had Stabilizers a. Kept the ship from rocking b. Less sea sickness c. Cargo less likely to get damaged vii. Had indents in the sails to catch more wind. viii. The sail could be angled to sail into the wind. a. Shorter journeys a. Steel ships i. Steel is stronger and safer ii. You can make ships that are larger and carry more goods. iii. Allowed the development of submarines. a. This allowed the exploration of ocean depths. b. Caravelle


i.

Small light ship that could sail into the wind

ii.

Since it was small it could sail up rivers and shallow areas

iii.

Columbus used Caravelles to explore.

D. Galleons 1. large multi deck ships 2. had a round keel or bottom i. made them more stable a. could carry more goods b. carry more cannons c. were more profitable to trade with. Cannons i.

Invented by the Chinese

ii.

Later spread to Middle East even later to Europe

iii.

Were very heavy and difficult to control

iv.

Once on an Explorers ship a. You could defend yourself b. You could conquer new lands c. Scared natives with a loud boom.

Gunpowder


i. Allowed Explores to hunt for food once on land ii. Allowed to conquer new lands using guns and cannon. a. The Native Americans did not stand a chance. iii. It allowed European powers to fight over treasure, land and ocean Nuclear Missiles and nuclear Space Craft i.

Missiles that delivered nuclear warheads were first used to send things, dog’s cats, monkeys and even people into space.

ii.

The first space flight on a former nuclear missiles was Sputnik by the Soviet Union

iii.

Space craft that are powered by nuclear energy are suited for long missions a. More efficient and reliable b. Hope they don’t blow up in our atmosphere

Pulley i.

It could help sailors move heavy objects such as sails or cargo

ii.

With pulleys you needed less crew with more room for cargo and more profit.

Chinese Sails
