Testable Question
Definition:
Question you are trying to
answer in an experiment.
Good Formats:
What is the effect of the IV on
the DV?
How does changing the IV
affect the DV?
Can also say increasing/decreasing...
Notice theborders...

Hypothesis
Definition: A prediction
of how changing the
IndependentVariable will
affect the Dependent
Variable.
Good Format: If the IV
is increased/decreased, then
the DV will increase/
decrease/stay the same
because... ___________
Don’t write “IV” or
“DV”, you actually write
out what the variables
are you are testing..

IndependentVariable
The Input. What you change
or manipulate in an
experiment.
These are how you change or
manipulate the IV
Examples
IV: Levels of IV
Brands ofTissue: Kleenex, Puffs,Always Save
Height of hill: 1m, 2m, 3m, 4m
Number ofWashers: 2, 4, 6, 8
Type of Liquid: water, vinegar, rubbing alcohol, milk
Levels of the IV

DependentVariable
The Output in an experiment. It
happens as a result of what you
changed as the IV.
What you measure.
Will generally have a unit
of measurement.
(as in grams, meters, m/s, liters...)

Constants
Constants are all the things
(variables) that you do NOT change
in an experiment. Constants, you
keep the same during each test.
The control is used to compare
and see if changing the IV actually
matters.
Generally the least changed level of
the IndependentVariable.

science.
