Why or why not? Imagine what life would be like if you were confined to a submarine for an entire summer. What would you miss? What would be fun about it? Make a list of pros and cons and share it with a friend or family member.
Do they feel the same way as you do? What pros and cons can they think of? It may not be able to take you to the bottom of the ocean floor, but this homemade ship will put you in control of your very own submarine. So what are you waiting for? Are you ready to head down under, captain?
Does water really exert force on submerged things? You bet it does! To learn more about this force, check out The Pressure of Water experiment. All you'll need is your hands and a plastic baggie.
Share what you learn with friends and family members! Did you get it? Test your knowledge. What are you wondering?

May 24, Thanks for sharing your thoughts with us, Hannah! Malcolm Apr 27, Apr 28, Great information, Malcolm! Thanks so much for sharing what you know with us!

William Sep 5, Sep 8, Thank you for making this it was very interesting how they used compressed air to sink and float. I wonder what it would be like to work on one. Jun 22, John from England Apr 8, I do not like submarines and this website is dumb. Wonderopolis Apr 8, Wonderopolis Feb 24, Charlie Jun 12, This article was a very clear explanation for how a submarine works and I liked how they explained how buoyant force works.
I never knew it was so complicated. But I have one question, how does the captain control the submarine with his crew? Wonderopolis Jun 12, Nathan Mar 18, It seems like a cool experience going on a sub. Wonderopolis Mar 18, Some submarines use two hulls—one inside of another—instead of ballast tanks.
This design allows it to flood the outer hull with water, which causes the vessel to sink, while the crew work and live in the inner one. An example of a double hull design is the Russian Alfa Class submarine considered by many to be the hot rod sub of the Cold War for its incredible speed. Designed during the s, the Alfa Class submarine remains the fastest of its kind till this day, according to Foxtrot Alpha.
Brit Lab, YouTube. A supply of compressed air is maintained aboard the submarine in air flasks for life support and for use with the ballast tanks. In addition, the submarine has movable sets of short "wings" called hydroplanes on the stern back that help to control the angle of the dive.
The hydroplanes are angled so that water moves over the stern, which forces the stern upward; therefore, the submarine is angled downward. To keep the submarine level at any set depth, the submarine maintains a balance of air and water in the trim tanks so that its overall density is equal to the surrounding water neutral buoyancy. When the submarine reaches its cruising depth, the hydroplanes are leveled so that the submarine travels level through the water.
Water is also forced between the bow and stern trim tanks to keep the sub level. How do submarines empty ballast tanks? Where do submarines get air to surface? What happens to the crew when a submarine sinks? Could the Kursk crew have been saved? What happens if a submarine sinks too deep? Can a submarine survive a tsunami? Could you survive a meteor in a submarine?
