<RECENT VERSION>
Chemistry: .......Answer.........The study of atoms and molecules,
their structures, and their interactions to form various substances.
Physics: .......Answer.........The study of forces, energy and motion.
Earth Science: .......Answer.........This field focuses on Earth's
structure and composition, as well as the processes that change
Earth, such as volcanic and seismic activity.
Physical Science: .......Answer.........The scientific study of nonliving
matter. Ex: chemistry, physics, and Earth science.
,age 2 of 58
Astronomy: .......Answer.........The study of the moon, stars, and
other objects in space.
Controlled Experiment: .......Answer.........An experiment in which
only one variable is manipulated at a time..
Independent Variable: .......Answer.........The variable that is
manipulated in an experiment.
Dependent Variable: .......Answer.........The outcome factor; the
variable that may change in response to manipulations of the
independent variable.
Control Variable: .......Answer.........A variable that is kept
constant during a controlled experiment.
,age 3 of 58
Observational Study: .......Answer.........The systems are observed
as they appear in nature and researchers do not attempt to
change them.
Laboratory Experiment: .......Answer.........Researchers study the
system of interest in a highly controlled artificial setting (lab).
Physical Model: .......Answer.........A physical representation of an
object. Ex: Scaled down version of the solar system.
Conceptual Model: .......Answer.........A verbal or graphical
explanation for how a system works or is organized. Ex: posters,
charts.
Mathematical Model: .......Answer.........Uses different forms of
data to represent the way a system or process works. Ex:
formulas, graphs, mathematical means. Ex: F=ma (formula).
, age 4 of 58
Computer Model: .......Answer.........A computer program that
models an event or object. Important in explaining and
predicting natural phenomena. Ex: weather patterns, solar
system.
Principle of Falsification: .......Answer.........Principle that only
falsifiable statements can be subject to scientific inquiry.
Hypothesis: .......Answer.........A testable prediction, often implied
by a theory.
Theory: .......Answer.........A hypothesis that has been tested with a
significant amount of data.
Law: .......Answer.........A concise statement that is supported by
scientific evidence and repeated experiments. Describes a
widespread pattern in nature. Intended to be universal.
