The Nature Of Science Flashcards
(19 cards)
Bias
A preference for or against one idea, thing or person.
Constant
A quantity that is unknown but assumed to have a fixed value in a specified mathematical context.
Control
An experiment where one in which the subject or a group would not be tested for the dependent variable.
Density
Mass of a unit volume of a material substance.
Dependent Variable
Something that depends on other factors.
Experiment
A scientific test in which you perform a series of actions and carefully observe their effects in order to learn about something.
Graph
A diagram that represents the variation of a variable in comparison with that of one or more other variables.
Hypothesis
An educated guess
Independent Variable
A variable that doesn’t depend on other factors
Mass
The property of matter that measures its resistance to acceleration.
Model
A scientific model is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Scientific Law
The description of an observed phenomenon.
Scientific Method
a method of investigation in which a problem is first identified and observations, experiments.
Standard
An object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
Technology
Is science or knowledge put into practical use to solve problems or invent useful tools.
Scientific Theory
A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
Variable
A variable is anything that can change or be changed. In other words, it is any factor that can be manipulated, controlled for, or measured in an experiment.
Volume
The amount of space occupied by a three-dimensional object or region of space. Volumes are expressed in cubic units.
SI
A complete metric system of units of measurement for scientists; fundamental quantities are length (meter) and mass (kilogram) and time (second) and electric current (ampere) and temperature (kelvin) and amount of matter (mole) and luminous intensity (candela)
