Chapter 1.2
Independent, Dependent, and Controlled Variables Master Fair Science Testing
You will discover how to identify the three types of variables in any experiment and use them to design tests that are fair and trustworthy.
What You'll Learn
You change the independent variable on purpose in every experiment.
You measure the dependent variable to see your experiment results.
You keep controlled variables the same to ensure fair testing.
You need only one independent variable for trustworthy science results.
What You'll Practice
1
You will identify independent and dependent variables in real experiments.
2
You will match variable types to their correct scientific definitions.
3
You will decide which variables must stay the same for fairness.
Why This Matters
Understanding how to control variables helps you design fair experiments and trust your results, which is a skill you will use in every science investigation you ever do.
