This topic covers Density -- Claimed by Christopher Lee, M03 Gumbart
The Main Idea
Density can be simply defined as the relative compactness of a substance. The consistency of the matter at hand can be quantified by mass per unit volume.
A Mathematical Model
Density = Mass / Volume
The mass can be expressed in grams [g] or kilograms [kg], and the volume is measured in liters [L], cubic centimeters [cm^3], or milliliters [mL].
A Computational Model
define mass and volume. ex: m = 500 vol = 40 density = m / vol
Examples

Connectedness
Density is important in construction of biomaterials that could potentially have clinical applications.
History
Archimedes in 250 B.C. "discovered" density. He suspected that he was being cheated on by the metal craftsmen who had constructed his golden crown. Archimedes suspected that the craftsman was using a sizeable amount of silver with his gold crown, which is cheaper, and ultimately an insult to the king. Archimedes put the crown that the craftsmen had created as well as a crown of pure gold both into a bathtub full of water. He measured the amount of water that was in excess and confirmed his suspicions. He then proceeds to chant "Eureka! Eureka!" in the streets.
