Density is a physical property of matter. It is also a mathematical relationship that exists between mass and volume. Just because something has a large mass doesn't mean it will sink. And just because something is lightweight doesn't mean it will float!
Whether something sinks or floats also depends on its density. In second grade terms, density describes how packed a material is. The more it is packed, the more mass has been crammed into a specific volume. Increase the volume, and the mass has more room to move around and is therefore less dense. Since ocean engineers design technologies that need to sink and float, being able to manipulate these factors is
