Chapter 1: Modeling Our Orderly World Flashcards
The systematic study of the universe to produce observations, inferences, and models.
Science
An event or a fact being studied.
Phenomenon
The study of nonliving matter energy.
Physical Science
The study of the composition, structure, and properties of matter as well changes in matter, and includes models of atoms, chemical reactions, the periodic table, and the behavior of gases.
Chemistry
The study of matter and energy and the interactions between them, and include models of motion, the behavior of fluids, and nuclear reactions and forces.
Physics
Evidence of an orderly world:
Days, seasons, years, and the periodic table.
Nature acts that same today as it did yesterday and that we can fully expect it to act the same way tomorrow.
Principle of Uniformity
Every effect has a specific, identifiable cause, there is a definite and predictable effect.
Law of Cause and Effect
Data that is based on numbers or quantities; includes a number and a unit; also known as quantitative data.
Measurement
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 unit.
Derived Unit
Two quantities with different units that are equivalent to each other and that are written as a fraction.
Conversion Factor
The force of gravity acting on the matter in an object.
Weight
The measure of the amount of matter in an object.
Mass
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 view
A system of moral values; a theory of proper conduct.
Ethics
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; Explanation of uniform patter of behavior.
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.
Workablility
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; Temporary explanation of observation.
Hypothesis
A standardized system of measurement units used for science.
SI
