Back

The variable that is measured to get results in an experiment. It depends on the independent variable.

Front

What is an Independent Variable (IV)?

Back

The variable that is deliberately changed or manipulated by the scientist in an experiment.

Front

What is a Constant Variable?

Back

Variables that are kept the same throughout an experiment to ensure a fair test.

Front

What is a Testable Question?

Back

A question that can be answered through experimentation and observation.

Front

What is a Non-Testable Question?

Back

A question that cannot be answered through scientific experimentation.

Front

In the question 'Does a metal baseball bat vibrate more than a wooden baseball bat?', what is the DV?

Back

The amount of vibration.

Front

In the question 'How does the type of ball affect the distance it rolls off a ramp?', what is the IV?

Back

The type of ball.

Front

What is the purpose of identifying variables in an experiment?

Back

To understand how different factors affect the outcome of the experiment.

Front

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

Back

To ensure that the experiment is fair and that the results are due to the independent variable.

Front

What is an example of a dependent variable in a plant growth experiment?

Back

The height of the plants after a certain period.
