Does anyone know the procedure, materials, and other data needed for this science fair project?
As far as I know rust only applies to ferric materials. Corrosion is a better name. The first link explains a bit. The corrosion rate may be less than 1 mm per year, so you have to consider how you will measure it. Start with clean metals, no grease or finger prints or oxides. The difference will easily be seen if one set of samples is in a refrigerator at 2 or 3 degrees, and the other is in a bath held at about 25C. However you may have to wait a long time. Take a series of photos of the samples, under the same lighting conditions over a period of time. Use the daylight setting of colour balance, not the automatic. The first link helps. While the reaction is chemical, it involves galvanic action (like a battery).Corrosion needs an electrolyte (impurities in water are enough), two dissimilar active materials (oxygen or another metal are most common) and an electrical path joining the metals together. Maybe you should consider other materials in sheet form like copper, brass, aluminium,
