Environmental Science and Scientific Method Vocabulary

Vocabulary flashcards covering fundamental definitions, environmental problem-solving steps, experimental variables, feedback loops, and Ostrom's principles for managing a commons.

Theory

An integrated explanation supported by a large body of observations and experiments, and evaluated by peer review, which simplifies, clarifies, and predicts new relationships within the natural world.

5 Steps to Addressing an Environmental Problem

1) Scientific assessment, 2) Risk Analysis, 3) Public education & Involvement, 4) Political Action, and 5) Long-term Evaluation.

Environmental Science

An interdisciplinary study of human relationship with other organisms and the Earth.

System

A set of components that interact and function as a whole.

Ecosystem

A natural system consisting of a community of organisms and its physical environment.

Dynamic Equilibrium

A steady state in which most of the Earth's systems exist.

Negative Feedback Loop

A response loop where a change triggers a response that counteracts (reverses) the changed condition.

Positive Feedback Loop

A response loop where a change triggers a response that intensifies the changing condition, such as glacial ice melt.

Variable

A factor that influences a process and may be altered in an experiment to determine its effect on the outcome.

Control

Part of an experiment where nothing is changed and the variable is not altered so you can see what happens naturally.

Scientific Method

A systematic investigative process consisting of: Recognize the problem, Develop Hypothesis, Test the Hypothesis, Analyze Data, Draw a Conclusion, and Share Result.

Ego Focus

A perspective that focuses on MYSELF.

Eco Focus

A perspective that focuses on the WHOLE GROUP and the PLANET.

Ostrom's 8 Principles for Managing a Commons

1) Strong group identity & understanding of purpose, 2) Fair distribution of Costs & Benefits, 3) Fair and Inclusive decision making, 4) Monitoring agreed upon behaviors, 5) Graduated Sanctions for Misbehaviors, 6) Fast & Fair conflict resolution, 7) Authority to Self-Govern, and 8) Appropriate relations with other groups.

Economically Viable Decisions

Decisions that make financial sense and ensure economic sustainability within environmental frameworks.

Socially Equitable Decisions

Decisions that maintain fairness and social balance across groups within environmental frameworks.
