| Science | a process for producing knowledge methodically and logically |
| reproducibility | making an observation or obtaining a particular result more than once |
| replication | repeating studies or tests |
| significant number | a level of detail that you actually know |
| deductive reasoning | deriving testable predictions about specific cases form general principles |
| inductive reasoning | inferring general principles from specific examples |
| hypothesis | a provisional explanation that can be tested scientifically |
| scientific theory | an explanation that has been supported by a large number of tests, and a majority of experts have reached a general consensus that it is a reliable description/ explanation |
| natural experiment | a study that involves observation of events that have already happened |
| manipulative experiments | studies in which conditoins are deliberately altered, and all other variables are held constant |
| controlled study | comparisons are made between experimental and control populations that are identical in every factor except the one variable being studied |
| blind experiments | researcher doesn't know which group is treated until after the data have been analyzed |

| models | a simple representation of something |
| systems | networks of interactions among many interdependent factors |
| open systems | those that receive inputs from their surroundings and produce outputs that leave the system |
| positive feedback | self-perpetuating process. plant grows leaves, more leaves= more energy it can capture for producing more leaves |
| negative feedback | supresses change; grass grows rapidly, mor leaves that can be supported by soil moisture, insufficient moisture= plant dies |
| equilibrium | tendency to remain more or less stable and unchanging |
| disturbances | events that can destabilize or change a system |
| dynamic equilibrium | tendency for a system to change and then return to normal |
| resilience | ability to recover from disturbance |
| state shift | conditions do not return to normal |
| emergent properties | characteristics of whole, founctioning systemst hat are quantitatively or qualitatively greater than the sum of the systems' parts |
| scientific consensus | general agreement among informed scholars |
| paradigm shifts | occur when a majority of scientists accept that the old explanation no longer explains new observations very well |
| ecofeminism | a plualistic, nonhierarchical, relationship-oriented philosophy that suggests how humans could reconceive themselves and their relationships to nature in nondominating ways as an alternative to patriarchal systems of domination |
