Learning the kinds and causes of corrosion, and techniques on how to prevent, control and mitigate it is the first step in combating this process.

A variety of resources are avaialable for teachers and the public from the DoD Corrosion Policy and Oversight Website.

Protocol 424

Do you have what it takes to fight Corrosion? Find out here as you take on Protocol 424; an e-learning game where you will build, repair, and maintain infrastructures within an old R&D base.

Coin Battery

Stack metals togrther to make a battery.

Copper Plating

In this demo we are forcing the ANODIC reaction of iron corrosion by pulling electrons out of the iron and “pumping” them over to the graphite rod where it allows a CATHODIC reaction of that converts water to hydrogen and GAINS electrons in the process. The overall reaction would go spontaneously but we are making it go faster with a battery (an electron pump).

How to Make a Rubber Band Car

Energy is neither created nor destroyed it is only transformed. Kinetic and potential energy are often paired together in simple demonstrations like a Rubber Band Car.


Corrosion is the chemical reaction where metals break down slowly because of other elements in their environment. For example when you see a rusty car or bridge, corrosion is the cause. Rusting, a well known example of corrosion, is the breakdown of the metal iron.


Every day bridges, automobiles, aircraft, and hundreds of other items made of metal corrode bit by bit. Produced for the DoD Corrosion Office by Bruno White Entertainment as part of a comprehensive series of  videos about corrosion,LaVar Burton describes the degradation process through video clips and visual images. This video would be a great introduction to any lesson involving corrosion.

Corrosion Investigation (Worksheet pdf file)


What are the three conditions that cause iron to rust?


1. Four Test Tubes
2. One Test Tube Stopper
3. Four Iron Nails or Iron Shavings
4. Water
5. Oil
6. Salt


Place an iron nail or iron shavings in each of the test tubes along with the designated ingredient(s). Place the test tubes on a shelf. Check in 24-48 hours to see if any rust has formed. Report your results on the worksheet.

Test Tube Conditions Results
1 Boiled Water and Oil Layer


2 Salt Water (electrolyte)


3 Air


4 Air and Calcium Chloride

Because saltwater is a better conductor than freshwater, the rate of metal corrosion is much higher in seawater. Corrosion of metal due to a stray electric current in water is referred to as stray current corrosion. This type of corrosion is particularly destructive in ports where a stray current can induce corrosion on multiple vessels as electrons flow from the metal, through the water, and into the ground. Corrosion prevention and control (CPC) is a significant part of the Navy’s budget (
