Rusty Nail Experiment

Materials Needed:

  • Two nails/group, same size and brand, galvanized
  • 16 oz, mason jars with lids, two per group
  • 300 ML salt water (ocean water)
  • 300 ML fresh water (crystal spring distilled water)
  • Forceps
  • Thermometer
  • Camera to record results
  • Balance scale (before/after)
  • Graduated cylinder (2)
  • Labels (salt water) (fresh water)


Step 1: Gather all your materials, and open your mason jars, and weigh the 2 nails.                                           Step 2: label your mason jars (salt/fresh)                                                                                                               Step 3: pour salt water into graduated cylinder until it reaches 300 ML, pour it into your mason jar labeled salt water.                                                                                                                                                               Step 4: Take a clean graduated cylinder and pour crystal distilled water in 300 ML, pour into your mason jar labeled fresh water.                                                                                                                                                Step 5: Next slowly put 1 nail into each jar at the same time and close the lids.                                                  Step 6: This procedure will probably take 2- 3 weeks, so wait patiently.                                                              Step 7: Check for rust daily from 7:00 am to 8:00 am, record picture and written evidence.                                Step 8: Keep your mason jars shaded and away from sunlight.                                                                                                                                                                 PAYTON
