To design a experiment to investigate what causes iron to corroide and which are the best way to prevent it?

hello, i just get my chemistry EEi today

we need to design a experiment to investigate what causes iron to corroide and fins out which is the best way to prevent it from rust?

cause this is the last year of high school, this experiment cannot be simple as before in yr 10...

anyone can give me a idea how can i do it>?

and tell me what kind of prevention can we have>?

Here is some ideas on prevention. The most common is a protective coating, paint. Trouble is it wears and cracks. If you try to paint over without removing all oxidation it will break through from under the paint.
Another method is metal plating where metals are put in different solutions to clean it, then coated with protective coatings using elecyto chemical reaction to bond the protection to the metal.
My company has water pumps which have anode protection. The corrosion attacks what is called a sacrificial anode and not the pump or its components. On the intake of the pump is a screen which keeps out debris and also is an anode so it does two jobs. The anode will corrode away and must be replaced every couple of years.
Tanks holding water can be protected by anodes suspended in the tank which corrode instead of the tank. Tanks holding gasoline or oils can get water which builds up in the bottom letting the water react with the metal. An anode attached to the tank can prevent its corroding. These require no outside power source.
The Navy uses cathodic protection around ships in storage. Cables in the water around the ship have electricity in them. This breaks the reaction which causes the corrosion.
Rust, oxidation or corrosion is different names for the same problem. You have to break the electrolysis reaction.

Hope this gives you some ideas.
