For you Science Fair Procedure, you need to plan how you will change your independent variable and how you will measure the impact the change has on dependent variable. Controlled variables must remain constant to get consistent results. You should include how many trials you intend to run, which is usually 3 times. Finally, show a step-by-step list of everything you must do to perform your experiment and tell what changes a person should expect.
