Oceanography – Submarine Challenge

Oceanography – Submarine Challenge

Today the students started wrapping up their submarine designs. Submarines are a special vehicle that can be submerged and operated under water. Submarines must operate in agreement with natural laws like Archimedes’ Principle and natural forces like gravity, the buoyant force, and water pressure. Typically, a submarine has compartments that facilitate how it maneuvers (up or down) the depths of the ocean. A ballast tank is a compartment that holds air and water. The submarine pumps water and air in and out of its ballast tanks to manipulate its mass and therefore, its density. Different proportions of air and water help it rise or sink in the ocean based on the density of the entire vehicle.

Ask your camper: How did you design your submarine so that it could maneuver up and down in the water?
