Variables in a scientific experiment include the independent and dependent variables. Constants are essential to maintain consistency, and the independent variable is crucial for establishing cause-and-effect relationships.
Variables in a scientific experiment: In any scientific investigation, variables are factors that can change. They include the independent variable, which is the factor being manipulated, and the dependent variable, which is the factor being measured.
Role of the independent variable: The independent variable is controlled by the experimenter to see its effect on the dependent variable, aiding in establishing cause-and-effect relationships.
Purpose of constants: Constants are kept constant to prevent them from affecting the results, ensuring that any changes are due to the independent variable alone, thus enhancing the validity of the experiment.
