Document Summary
A representation of something, typically a simplification of something complex. What goes in, how the system is impacted, what are the outcomes can be used for learning, and prediction. Models can be viewed as testable hypothesis, refutable with laboratory and field observations. Models and observations can be used to advance understanding in an iterative manner. Models used to design collection of data. Data can then be used to re-design/refine models. Graphical & quantitative representation of a system shows essential features rates of movement into or out of sys rates of movement or change within sys amount of matter or energy in sys processes responsible for movement/change. # of reservoirs depends on the information and the question at hand and the scale. Cycles: closed systems that describe the flux of material between reservoirs steady state: amount in reservoir remains constant with tim. Neither created or destroyed, but can change form. Number of reservoirs depends on information and.
