Hypothesis: If the temperature of the water is hot, then the more rust will form on the alumnimun. Question: How does temperature affect the corrosion of aluminum? **Materials: ** 1. Aluminum plates, all the same size 5 cm X 5 cm 2. 5 beakers (measuring cup) 3. 2500 milliliters of water (500 mL in each beaker) 4. Baking soda 5. Salt 6. Hotplates 7. A scale 8. Vegetable oil 9. Thermometers 10. Spatula (for mixing) 11. Ferric chloride (?) 12. Data chart  **Procedure: ** 1. Cut or make sure all aluminum plates are the same sizes to begin 2. Measure out 500 mL of water and pour it into each of the 5 beakers 3. Measure out 18 g of salt and baking soda or ferric chloride and pour each of them into the beakers 4. Mix each of the solutions with the spatula in the beakers 5. Place one aluminum plate into each of the beakers 6. Pour 3mm of vegetable oil over the beaker and place a thermometer in each 7. Store the first beaker at room temperature for 5 days (25 degrees Celsius) 8. Put the remaining four beakers at temperatures of 20°C, 35°C, 50°C, and 75°C 9. Check thermometers throughout the process that the temps are remaining the same 10. Check each of the aluminum plates after 5 days for any signs of corrosion or marks 11. Repeat procedure 7 times
