the nature of science Flashcards
bias
a preference for or against one idea.
constant
A quantity that is unknown but assumed to have a fixed value in a specified mathematical context.
control
In scientific experiments, a scientific control is one in which the subject or a group would not be tested for the dependent variable(s)
density
Density, mass of a unit volume of a material substance.
dependent variable
It is 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 (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables.
hypothesis
a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
independent variable
An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
mass
A measure of the amount of matter contained in or constituting a physical body.
model
A scientific model is a physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
scientific law
In general, a scientific law is the description of an observed phenomenon. It doesn’t explain why the phenomenon exists or what causes it
scientific method
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
standard
In metrology (the science of measurement), a standard (or etalon) is an object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
technology
the application of scientific knowledge for practical purposes, especially in industry.
