### Developing a Question Using Variables

Created by Marcie Griffith 2012

Research questions are are framed around the possible relationship between an independent and dependent variable.

Independent Variable relationship between an

• Variable I will manipulate (change) in the experiment

• Only 1 independent variable allowed

Dependent Variable relationship between an

• What I will measure

• Data I will record

• The result DEPENDS on my independent variable

Posing Your Question relationship between an

What happens to ____________ when we

(Dependent Variable)

change ____________________?

(Independent Variable)

OR

How does ___________________ affect

(Independent Variable)_________________?

(Dependent Variable)

Let’s Practice! relationship between an

Observation- Handball Court relationship between an

I noticed that students who won the most handball games, were those who could bounce the ball over their opponent’s head.

How much does the ball have to do with the bounce height?

Research questions are written in the form of a question about the possible relationship between an independent and dependent variable.

Research questions are written in the form of a question about the possible relationship between an independent and dependent variable.

Research questions are written in the form of a question about the possible relationship between an independent and dependent variable.

ONLY 1 Independent Variable Allowed!

Research questions are written in the form of a question about the possible relationship between an independent and dependent variable.

Research questions are written in the form of a question about the possible relationship between an independent and dependent variable.

What happens to about the possible relationship between an bounce heightwhen we change the color of the ball?

OR

How does ball coloraffect bounce height?

• What is the independent variable?

• What is the dependent variable?
