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 • Variable I will manipulate (change) in the experiment • Only 1 independent variable allowed
Dependent Variable • What I will measure • Data I will record • The result DEPENDS on my independent variable
Posing Your Question What happens to ____________ when we (Dependent Variable) change ____________________? (Independent Variable) OR How does ___________________ affect (Independent Variable)_________________? (Dependent Variable)
Observation- Handball Court I noticed that students who won the most handball games, were those who could bounce the ball over their opponent’s head.
Let’s apply the scientific method to help my answer my question This made me wonder… How much does the ball have to do with the bounce height?

What happens to bounce heightwhen we change the color of the ball? OR How does ball coloraffect bounce height?
Head’s Together! • What is the independent variable? • What is the dependent variable?
Controlled Variables What’s wrong here? 15 ft Drop Height 10 ft Drop Height How might this impact our experiment?
Controlled Variables What’s wrong here? 15 ft Drop Height 15 ft Drop Height What variable might this scenario test?
Controlled Variables 15 ft Drop Height 15 ft Drop Height What variable might this Scenario test?
Controlled Variables How many times should I repeat the measurement? 15 ft Drop Height 15 ft Drop Height
Continuing the Experiment • Conduct Experiment • Take Multiple Measurements • Represent Data • Interpret Data & Draw Conclusions • Future Research/Next Steps • Share Findings
