The video tutorial explains the concepts of independent, dependent, and controlled variables in scientific experiments. It uses the example of sunlight affecting plant growth to illustrate these concepts. The independent variable is the factor changed by the experimenter, while the dependent variable is the observed effect. Controlled variables remain constant to ensure accurate results. The video also discusses experimental and controlled setups, emphasizing the importance of observing changes in dependent variables due to independent variables. The tutorial concludes by summarizing the relationships and roles of these variables in experiments.
