Scientific Method Variables

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment. It changes in response to the independent variable.

Front

What is the independent variable in an experiment?

Back

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

Front

What does DV stand for in scientific experiments?

Back

DV stands for Dependent Variable, which is the variable that is measured in an experiment.

Front

What does IV stand for in scientific experiments?

Back

IV stands for Independent Variable, which is the variable that is changed in an experiment.

Front

What is a controlled experiment?

Back

A controlled experiment is a test where only one variable is changed at a time while all other variables are kept constant.

Front

Why is it important to have a control group in an experiment?

Back

A control group is important because it provides a baseline to compare the results of the experimental group, helping to isolate the effect of the independent variable.

Front

What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout the experiment to ensure that the test results are valid.

Front

How many independent variables should be tested in a controlled experiment?

Back

Only one independent variable should be tested in a controlled experiment to ensure clear results.

Front

What is the purpose of repeating trials in an experiment?

Back

Repeating trials helps to ensure the reliability and accuracy of the results by minimizing the effects of random errors.

Front

What is the role of observations in the scientific method?

Back

Observations are used to gather data and evidence that can lead to questions, hypotheses, and conclusions in the scientific method.
