Testable Questions
Testable Questions have Variables:
• an dependent variable
• an independent variable
• controlled variables
Independent Variable
The single condition that will be
changed in an experiment
Dependent Variable
The condition that will be
measured in an experiment
Controls (Controlled Variables)
The conditions that are kept the
same (unchanged) in an experiment
Testable QuestionDoes changing the height of the
ramp affect the speed of the car going down the ramp?

Testable or Not Testable?
Testable Questions need 2 parts
1. An Independent variable
2. A dependent variable
Testable or Not Testable? Is this a testable question?
How does a paper airplane fly?
No, because there is not anindependent variable and adependent variable in the question.
Make the Question Testable
To change
testable:
the question so it is
First list some variables that youcould manipulate (change) that are involved
with flight of a wing shape body shape
paper airplane
type of paper used
Make the Question Testable
Second, decide what you are goingto measure (dependent variable). For example: Distance the plane will fly
Length of time the plane stays in the air
Make the Question Testable
Now, select one independent variable and one dependent variable. Put them together to create the testable question. For example:
Make the Question Testable
Does
wingchanging
affect thethe shape of
distance the will fly?
the shape of
the
paper airplane
Does changing body affect the paper airplane air?
thelength of time the
will stay in the
