What is a variable held constant in an experiment?

Back

A variable that is kept the same throughout the experiment to ensure that the results are due to the independent variable.

Front

What is the Independent Variable?

Back

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

Front

What is the Dependent Variable?

Back

The variable that is measured or observed in an experiment; it is affected by changes in the independent variable.

Front

What is a Control in an experiment?

Back

A standard for comparison that is not exposed to the experimental treatment.

Front

Why is it important to have a control group?

Back

A control group helps to isolate the effects of the independent variable by providing a baseline for comparison.

Front

What is a hypothesis?

Back

A testable prediction about the relationship between two or more variables.

Front

What is the purpose of repeating experiments?

Back

To verify results and ensure that they are reliable and not due to chance.

Front

What is a factor in an experiment?

Back

Any condition or variable that can affect the outcome of the experiment.
