Experimental Variables

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated in an experiment to test its effects on the dependent variable.

Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is a control in an experiment?

Back

A control is a standard of comparison in an experiment, which remains constant and is not affected by the independent variable.

Front

How does the type of gasoline affect a car's performance?

Back

The type of gasoline is an independent variable that may influence the dependent variable, which is how fast the car can drive.

Front

In an experiment, what is the purpose of having a control group?

Back

The control group serves as a baseline to compare the effects of the independent variable, helping to isolate the results.

Front

What is the significance of timing in experiments involving puzzles?

Back

Timing allows researchers to measure the dependent variable (time taken) and analyze how it relates to other factors, such as age.

Front

What is the relationship between studying and test scores?

Back

Studying is the independent variable that is believed to influence the dependent variable, which is the test score.

Front

In Mr. S's experiment, what does the mass of the ball represent?

Back

The mass of the ball is the independent variable that is being tested to see how it affects the dependent variable, which is the distance traveled.

Front

What is the role of the type of paper airplane in an experiment?

Back

The type of paper airplane is the independent variable that is tested to determine its effect on the distance it can fly.

Front

Why is it important to identify variables in an experiment?

Back

Identifying variables helps clarify the relationships being tested and ensures that the experiment is designed to yield valid results.
