*For this experiment, the independent variable is the use of protective sealant and the type of materials used to act as the corrosive agent. The dependent variable is the appearance of rust or corrosion on the metal sheets over time. The constants (control variables) are the type of metal sheets used, the temperature, amount of sunlight and type of paint used. *The experiment is begun by spray painting all of the 20 metal sheets and allowing them to dry for 8 hours. *10 plates are separated and applied with a coating of protective sealant. The metal sheeets with the ..... |
