Worksheet: Identifying Variables
Name: _______________________Date: _______________________
Identify the Independent, Dependent and Control Variables in
each experiment below.
Reminder:
INDEPENDENT VARIABLE – The variable to change in an
experiment
DEPENDENT VARIABLES – The variable to measure in an
experiment
CONTROLLED VARIABLE – The variables we do not want to test so
ensure they remain the same through the experiment.

Example: An experiment to see if the brand of glue affects the
stretchiness of slime being made?
Independent Variable: The brand of glue
Dependent Variable: The stretchiness of the slime
Control Variables: The amount of each ingredient, how
fast and long you are mixing when making the slime,
how fast you are stretching when testing the
stretchiness, the temperature of the room (and many
more)
