What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

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 constant in an experiment?

Back

A constant is a factor that remains the same throughout an experiment to ensure that the test results are valid.

Front

What is the purpose of a control variable?

Back

Control variables are kept constant to ensure that any changes in the dependent variable are due to the independent variable.

Front

Give an example of an independent variable in a plant growth experiment.

Back

The type of fertilizer used is an independent variable.

Front

Give an example of a dependent variable in a distance rolling experiment.

Back

The distance traveled by the ball is a dependent variable.

Front

What is the difference between independent and dependent variables?

Back

Independent variables are manipulated to observe their effect, while dependent variables are measured to see how they respond to changes in the independent variable.

Front

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

Back

Control variables are important to ensure that the experiment is fair and that the results are due to the independent variable.

Front

What does it mean if a variable is not a constant?

Back

If a variable is not a constant, it means that it can change or vary during the experiment, potentially affecting the results.
