(19 cards)
Bias
A preference for or against one idea, thing or person.
Constant
A quantity unknown but assumed to have a fixed value in a specified mathematical context.
Control
One in which the subject or a group would not be tested for the dependent variables.
Density
A 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 preform a series of actions done to carefully observe their effects in order to learn.
Graph
A diagram that represents the variation of a variable in comparison with.
Hypothesis
An idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world.
Independent Variable
It is a variable that stands alone and isn’t changed by the other variables you are trying to measure.
Mass
A measure of the amount of matter contained in or constituting a physical body.
Model
A physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Scientific Law
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena.
Scientific Method
The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation.
Standard
An object, system, or experiment that bears a defined relationship to a unit of measurement of a physical quantity.
Technology
The definition of technology is science or knowledge put into practical use to solve problems or invent useful tools.
Scientific Theory
A scientific theory is an explanation of an aspect of the natural world and universe that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results.
Variable
Anything that can change or be changed.
Volume
To the three-dimensional space that is occupied by an object.
SI
The International System of Units is the modern form of the metric system. It is the only system of measurement with an official status in nearly every country in the world.
