Corrosion



What are you investigating?
To investigate the factors that cause rust in iron

What do you think will happen?
I think that the nail with the nail polish, calcium chloride and oil will prevent corrosion. I think that the Saltwater, water and magnesium will cause corrosion.

What is corrosion?
When metals are exposed to the environment they can deteriorate, or break down.

Observations

Saltwater and water caused the nail to corrode because of the water and oxygen. Nail polish, Magnesium, Calcium Chloride and Oil prevented the nail from rusting.

    Great Work Loishane! Why do you think the magnesium, nail polish, calcium chloride, and oil prevented rust?
