Inside the Battleship IOWA Oil and Water Laboratory: How Sailors Monitored a Battleship's Engineering Systems How did sailors aboard the Battleship IOWA monitor the oil and water needed to operate one of the U.S. Navy's most powerful battleships? In this behind-the-scenes tour, Battleship IOWA crew member Don takes viewers inside the ship's Oil and Water Laboratory, located on the third deck just off Broadway—the longest passageway aboard the ship. The laboratory played an important role in...

What is the difference between a knot, a bend, and a hitch? For sailors, knowing how to properly handle and secure a line is a fundamental seamanship skill that has been used aboard ships for generations.

How Does a Battleship Float? Exploring the Science of Buoyancy How can a massive battleship made of thousands of tons of steel float on water? The answer is buoyancy—one of the fundamental principles of science, engineering, and naval architecture. In this Battleship USS IOWA Weekly STEM Challenge, students explore the science behind why some objects float while others sink and discover how the principles of buoyancy help enormous ships like the Battleship USS IOWA remain afloat. What Is...

How Do Marine Animals Control Buoyancy? How do marine animals float, sink, or remain suspended in the ocean? The answer comes down to buoyancy—the same scientific principle that helps a massive ship like the Battleship USS IOWA stay afloat. In this STEM education video, Battleship USS IOWA Museum and Cabrillo Marine Aquarium in San Pedro, California, explore the science of animal buoyancy and the fascinating ways marine organisms adapt to life in the ocean. The lesson looks at how marine...
