How can I test this hypothesis?
What is a way that I could test this hypothesis?
P.S. Do you think this is a good hypothesis?
Thanks for your help!
Answer:
To test: I'm presuming your only testing iron and iron alloys since you use the term rust.
Procure samples of several types of steel/iron (perhaps with several types of protective coatings (paint, galvanizing, tin plate, etc. Leave one set outside and record amount of rain exposure (or set up a hose nozzle to spray a constant, known quantity of mist on the samples for specified times (would be more quantitative and reproducible). Keep another set of samples indoors in a dry place. Observe the samples each day and note any evidence of rusting (you might want to take a digital photo of the samples each day for a record).
Well, you would need a control and a way to test this. In order to test to see if the rain is the cause, you would need to keep a piece of metal in the same environmental condition (temperature, humidity, light exposure, etc.) as the test metal, but the test metal would have to be exposed to the rain.
This experiment might be more of a long term project because it is hard to conduct the experiment; you are at the mercy of mother nature. But if you have the time, give it a shot.
That is good...sort of..you should say "water" rusts metal..but if you have to say rain that is a true statement.. The physical property's of rain and water are. almost identical..so all you have to do is find a rusted nail and say it was because of water ex posher..Which it was..if you have to do it you self and want to see the process at work..just put a nail in water..It will take about 10 weeks...I would recommend finding a rusted nail.
