Answer (1)
Variables1. Independent VariableThe factor that you purposely change or control in an experiment to see its effect.Example: amount of fertilizer, number of study hours, water temperature.2. Dependent VariableThe factor that you measure or observe as a result of the changes in the independent variable.Example: plant height, test score, time for sugar to dissolve.3. Controlled VariablesThe factors that are kept the same to make sure the experiment is fair and that only the independent variable is causing the change.Example: type of soil, amount of water, type of plant, location of experiment.4. Dependent Variable The result being measured on each day (for example: plant height, number of leaves, or other measurable outcome).
