Chapter 1 Test Flashcards
A system of moral values or a theory of proper conduct
Ethics
The study of nonliving matter and energy
Physical Science
The systematic study of the universe that produces observations, inferences, and models, including the products that it creates through this systematic study
Science
The study of the composition, structure, and properties of matter, and the changes that take place in matter
Chemistry
The study of matter and energy and the interactions between them
Physics
A workable explanation or description of a phenomenon
Model
A model that explains a related set of phenomena; can be used to predict unobserved aspects of the phenomena
Theory
A model, often expressed as a mathematical equation, that describes phenomena under certain conditions
Law
The basis upon which a model is assessed, taking into account how well it explains or describes a set of observations and how well the model makes predictions
Workability
An ongoing, orderly, cyclical approach used to investigate the world
Scientific Inquiry
An initial, testable explanation of a phenomenon that stimulates and guides scientific investigation
Hypothesis
The basic law that states that every effect has a specific, identifiable cause, and for every cause there is a definite and predictable effect
Law of Cause and Effect
An observable or measurable event, object, process, or property
Phenomenon
The basic law that says that nature acts the same today as it yesterday and that we can fully expect it to act the same way tomorrow
Principle of Uniformity
How a person views the world; a set of basic beliefs, assumptions, and values that arises from an overarching narrative about the world and that produces individual and group action
Worldview
The apparent motion of some planets in which they appear to slow down, stop, reverse their direction, and then resume their normal motion
Retrograde Motion
The assessment process for scientific research in which other scientists review and respond to research
Peer Review
Data that is based on numbers or quantities; includes a number and a unit; also known as quantitative data
Measurement
A standardized system of measurement units used for science
SI
The comparison of a measurement to an accepted or expected value
Accuracy
The degree of exactness of a measurement; can indicate the closeness or repeatability of measurements
Precision
The collection of observations made by scientists during investigations
Data
A unit that is a mathematical combination of fundamental SI units
Derived Unit
