3 Variables Science Test

Front

What is a control variable in an experiment?

Back

A control variable is a factor that is kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

Why is it important to maintain control variables in an experiment?

Back

Maintaining control variables is important because it allows researchers to isolate the effects of the independent variable and accurately determine its impact on the dependent variable.

Front

What is the dependent variable in an experiment?
