1. Which liquid rusts a nail the most?

2. 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.

3. The Materials 9 clear cups 9 silver nails 15 ounces of rain water
15 ounces of coca cola
15 ounces of spring water

4. 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.

5. Graphed Results What liquid rusts a nail the most?
Signs of rust 3=most
1=least
Type of liquid the nail was placed in

6. 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.

7. Acknowledgements
I would like to thank the school for letting us use some of the schools clear plastic cups.
