Which metal is most resistant to corrosion?

= Project Proposal =

The topic that I have chosen to do my major project on is corroding metal, and the question I will be exploring further is “Which metal is most resistant to corrosion?” I will test which metal is most resistant by putting three metals in a range of liquids, and after a certain time period (approx. 2 weeks), I will be able to see the corrosion. Three sources of information I could use include my dad’s knowledge of metals, the internet (Wikipedia and corrosion doctor, which both have lots of useful information), as well as books about metals. For my experiment, the independent variable will be the different liquids I put the different metals into, the dependant variable is the amount of corrosion, and the controlled variable is the types of metal used. The materials I will need are: · Three metals (eg. Copper, aluminium, brass) · Three jars · Water · Salt water · Lemonade · Note book and pencils · Camera This practical will take about two weeks or more to be affective. I will probably only need to perform my experiment once, but if I get time I will do two trials. There isn’t really any safety concerns with this experiment because it is quite safe.
