What is the purpose of a controlled variable in a scientific experiment?

It is a factor that we keep constant to ensure a fair test.

It is the variable that we manipulate to test our hypothesis.

It is the variable that changes in response to the independent variable.

It is the outcome or result we are trying to measure.

Which of the following best describes the dependent variable in a scientific experiment?

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

The variable that we keep constant to ensure accuracy.

The variable that we manipulate to test our hypothesis.

The variable that we use as a standard for comparison.

In a science experiment, why is it important to clearly define and identify the variables?

To communicate the purpose and design of the experiment and its results effectively

To make the experiment more complicated

To ensure that the experiment is not repeatable
