Variables in Science Experiments: Practice!

Front

What is an independent variable in a science experiment?

Back

The independent variable is the one that is deliberately changed or manipulated to observe its effect on the dependent variable.

What is a dependent variable in a science experiment?

Back

The dependent variable is the one that is measured or observed in response to changes in the independent variable.

Front

What is a controlled variable in a scientific experiment?

Back

A controlled variable is a factor that is kept constant to ensure a fair test.

Front

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

Back

The control group serves as a standard for comparison, helping to isolate the effects of the independent variable.

Front

What is the difference between independent and dependent variables?

Back

The independent variable is manipulated by the experimenter, while the dependent variable is measured as a response.

Front

Why is it important to keep controlled variables constant?

Back

Keeping controlled variables constant ensures that the results are due to the independent variable and not other factors.
