variables - CORRECT ANSWER -The changing quantities in an experiment
independent variable - CORRECT ANSWER -What you change in an experiment on purpose
dependent variable - CORRECT ANSWER -The variable that changes because of an independent
variable
control variable - CORRECT ANSWER -The variable(s) you don't want to study, need to be either
eliminated or kept constant
,observational study - CORRECT ANSWER -When systems are observed as they appear in nature,
researchers do not attempt to change them
physical model - CORRECT ANSWER -A model of a physical phenomenon, such as a planetary
system
conceptual model - CORRECT ANSWER -A model used to visualize things that cannot be seen,
such as atoms

using mathematical methods
computer model - CORRECT ANSWER -A detailed, complex model calculated by a computer
principle of falsification - CORRECT ANSWER -Principle that only falsifiable statements can be
subject to scientific inquiry

law - CORRECT ANSWER -A concise statement that is supported by scientific evidence and
repeated experiments, describes a widespread pattern in nature (what)
theory - CORRECT ANSWER -A statement that explains a wide range of observations, supported
by a large body of scientific evidence (how/why)

Acceleration - CORRECT ANSWER -Term for any change in an object's speed and/or direction
Force - CORRECT ANSWER -Term for a push or a pull with direction and magnitude. You may not
feel it.
