Hypotheses
Independent
Variable
*Tentative and testable statements
that must be capable of being
supported or not supported by
observational evidence
*The factor that is adjusted by the
experimenter to see what effect the
change has on the dependent variable
*Plotted on the horizontal axis
Dependent
Variable
because of a change in the independent
variable
Conclusion
*A statement that identifies cause
and effect based on evidence
Inference
*A reasonable conclusion or
possible hypotheses based on
observations
*The factor whose value changes
*Plotted on the vertical axis
*The use of evidence to construct

Science Methodology/Lab Safety Matching Activity
*Well-established and highly reliable
Scientific theory
explanations
*Based on natural and physical
phenomena
*Capable of being tested by multiple
independent researchers
*Subject to change as new areas or
Scientific theory
science and new technologies are
developed
*Subject to change when new evidence is
inconsistent with or cannot be explained
by the current theory
*Generalizes a body of observations
Scientific law
At the time it is made, no exceptions
have been found; explains things, but
does not describe them
Investigation
*A test to determine a possible
answer to a proposed hypothesis
Data Table
Constant

*An organized chart on which to
keep data collected from the
independent and dependent
variables
*A variable that is not changed in
an experiment

*A standard set up in which all
variables are controlled and the
experimental results are compared
