Front

What is an independent variable?

Back

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

What is a dependent variable?

Back

The dependent variable is the variable that is measured and affected in an experiment, responding to changes in the independent variable.

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure that the results are valid.

Front

What is the purpose of a control group in an experiment?

Back

The control group is used as a standard for comparison to see how the independent variable affects the dependent variable.

Front

What does it mean to manipulate a variable?

Back

To manipulate a variable means to change it intentionally in an experiment to observe the effects.

Front

What is the relationship between independent and dependent variables?

Back

The independent variable is what you change, while the dependent variable is what you measure in response to that change.

Front

How can you identify the independent variable in a question?

Back

The independent variable is usually the factor that is being tested or changed in the experiment.

Front

What is an example of an independent variable?

Back

In an experiment testing how light affects plant growth, the amount of light is the independent variable.

Front

What is an example of a dependent variable?

Back

In an experiment testing how light affects plant growth, the growth of the plant is the dependent variable.
