Answers for Grades K-3:

 

1) In the relatively large, well-lit control room are the controls for nearly all the sub's vital operations.

2) False: Sound can’t travel in space at all because space is a vacuum, with essentially no molecules.

3) The control room is the brain of any submarine.

4) Whales living in shallower waters, like the humpback whale, make sounds that are melodic.

5) There is a lot of camaraderie and tradition in the submarine force and there are hardships to share. It's like a brotherhood on the boat, on all naval vessels really, but submariners are closer fraternally because of their utter dependence on one another professionally, and because their living space is tighter.

6) "Dolphins" is a pin like a pilot's wings that qualified submariners proudly wear.

7) The USS Springfield has the greater speed of 25 knots or 29 miles per hour. Its speed is relatively slow compared to that of a car.

8) Once they signed you off, you were qualified, you received your coveted Dolphins, and immediately after you were dismissed from quarters, somebody would grab you, and you'd be duly tossed overboard as a rite of passage. You were now a Submariner.
9) False. If submarine life not suited for you, you'll find out long before you go to sea on a submarine.

10) Sound travels at about 4,347 feet (close to a mile) per second in water in 68 degrees Fahrenheit.

 

Answers for Grades 4-8:

 

1) The lowest ranking of the enlisted men are traditionally assigned the duty of planesman and helmsman.

2) The bill to overhaul a Sturgeon-class sub for civilian science has been estimated at $50 to $200 million, with annual operating costs of perhaps $10 million.

3) Many sounds underwater animals make are for: 1) sending a defensive or attack warning signal, 2) helping the animal determine its location (echolocation), 3) communicating with other members of its kind, or 4) issuing a mating call.
4) Sturgeon-class subs can travel at over twenty-five mph and are not impeded by sea ice, storms, or the need to refuel often. As long as the ocean is deep enough, they can go anywhere they want. They are quiet, which is good for sonar work, and extremely stable, which aids gravity and bathymetry studies. And they're a lot more comfortable than a research camp out on the ice.

5) GPS stands for Global Positioning System.

6) A hydrophone is an underwater microphone that scientists use to listen to the sounds of the deep.

7) True

8) A Weapons Control Panel is the aft-most console and it houses the "fire" button. This ominous red button will launch a torpedo or Tomahawk missile from the sub.
9) Whale sounds have been heard thousands of miles away from where the sound originated.
10) “Snorkeling” is when you come up to 58 to 60 feet, and you raise two masts, the induction and exhaust masts. The induction mast comes up about 18 inches above the surface and allows you to start your main engines and charge your batteries and take in fresh air.

 

Answers for Highschool:

1) What you're really hearing when you hold a seashell to your ear is sound around you vibrating in resonance in the air within the shell.
2) The Navy has learned more about the polar region and what equipment they require to work there efficiently. They've earned good publicity by showing themselves as willing partners with science. Finally, they've maintained their training and operability in this distant corner of the planet.

3) Newton wants the Navy to give the science community one of its retiring Sturgeon-class subs for its exclusive, full-time use, not just in the Arctic but anywhere in the world/ocean it wants to take it.
4) The helmsman uses the aircraft-style controls to adjust the rudder while the planesman adjusts the diving planes.

5) It means that humans can't hear sounds above 20,000 vibrations per second.
6) In 1958, the USS Nautilus became the first submarine to travel under the Arctic icecap.

7) The Navy paid operational costs, while most scientific costs were shouldered by the National Science Foundation.

8) Newton was attempting to get Navy submarines to take civilian scientists to the Arctic, a place notoriously difficult to study. He succeeded when the Navy accepted the proposal by late 1992.

9) A “deterrent patrol” was a politically sensitive term for war patrols.
10) The Chief of the Watch sits outboard and uses the ballast control to adjust the trim of the submarine by adding or removing water from the variable ballast tanks, thereby adjusting the sub's buoyancy.
