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 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
