Variables in Science Experiments: Practice!

Front

What is a dependent variable in a scientific experiment?

Back

The variable that we measure or observe to see how it responds to changes.

Front

What is an independent variable in a scientific experiment?

Back

The variable that we deliberately change or manipulate to see its effect.

Front

What is a controlled variable?

Back

The variable that we keep constant to ensure accuracy in an experiment.

Front

What is a control group?

Back

The group in an experiment that does not receive the experimental treatment and is used as a benchmark.

Front

In an experiment, how do you identify the dependent variable?

Back

It is the variable that is affected by changes in the independent variable.

Front

What is the purpose of manipulating the independent variable?

Back

To observe how it affects the dependent variable.

Front

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

Back

To ensure that the results are due to the independent variable and not other factors.

Front

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

Back

The height or growth rate of the plants.

Front

Give an example of an independent variable in a temperature experiment.

Back

The temperature at which the experiment is conducted.

Front

What does it mean to measure a variable in an experiment?

Back

To collect data on how that variable changes in response to the independent variable.
