Purpose The reason I am doing this project is to see which liquids rusts a nail the most, rain water, spring water, and coca cola. Hypothesis I think that the rain water will rust it the most because at my house I have left my scooter out side in the rain for a long time and it rusted.
The Materials • 9 clear cups • 9 silver nails • 15 ounces of rain water • 15 ounces of coca cola • 15 ounces of spring water
The Procedures First I set out my nine cups and nine nails and filled each cup with Coke, Spring water, and Rain water. Then I placed a nail in three of the cups. Last I waited two days and checked them.
Graphed Results What liquid rusts a nail the most? Signs of rust 3=most 1=least Type of liquid the nail was placed in
Conclusion I think spring water won because it has no chemicals in it and rain water had fungus in it already. My hypothesis was wrong.
Acknowledgements I would like to thank the school for letting us use some of the schools clear plastic cups.
