Submarines, Density and Hydrodynamics and Electricity
Submarines rely on many scientific principles. This allows them to conquer the definitive boundaries of the material plane. One of the most important of these is buoyancy. Buoyancy is defined as how much something sinks or floats. Although many properties effect buoyancy, one of the main principals that effects it is density. Density is measured by how compact an object is, or how “squished together” the molecules are. Less dense objects float on more dense objects. The technical formula for density is D=M/V, which reads as Density equals Mass divided by volume. In the case of water (D= 1 gram/ 1 milliliter.), Its density is one gram per milliliter: If an object is less dense than water it will float, and anything denser than water will sink. Our challenge was to build a submarine that has a density close to water's density. (Click Here) this way our submarine would neither sink nor float, but hover in the water. On top of doing this, we developed a system that could change the actual density of our submarine, and make it ascend to the surface.

Besides density, something else my partner and I had to deal with was the concept of hydrodynamics. This concept covers how objects move through the water. Certain shapes, materials, and designs will be able to maneuver and work better under water than others, and we had to design a submarine that would be able to deal with all of this; maximizing it’s potential as an underwater machine.

Lastly, we needed some means to power our submarine, so we had to do a little research on the topic of electricity. It was not that extensive, but we figured out how to create basic circuits and switches (Click Here), so we could power our submarine from a remote location.
