Aim: We are investigating whether or not different liquids will cause corrosion to the nail.
What is corrosive: Corrosive is the breaking down of a metal. Corrosion is caused when metal atoms react with their environment
Liquids we are using with the nail:
Nail polish+water, oil, saltwater, calcium chloride+water, magnesium+water, water
Hypothesis:
Oil: I think the oil will cause corrosion to the metal because it can cause the metal to rust if the moisture diffuses through the oil.
Nail polish: I don't think that the nail polish will cause corrosion because it's like a protective layer to the nail so that it doesn't rust.
Saltwater: I don't think the metal will rust when in the salt water because I think that the salt will protect the nail.
Calcium Chloride: I don't think the metal will corrode in the Calcium chloride.
Magnesium: I think the metal will rust because magnesium is a light metal and isn't really protecting the nail.
Water: I think the water will cause corrosion with the nail because it's just water and there's nothing to protect the nail from rusting.
Results:
Oil: Out of all the solutions the oil caused the less corrosion and the metal didn't rust at all.
Nail Polish: The metal only rusted at the top where the nail polish wasn't on.
Saltwater: The metal corrosion the most in the saltwater and there was lots of rust.
Calcium Chloride: The metal didn't rust much but there was still a little bit at the bottom.
Magnesium:

Great Blog Alayna. I really liked the pictures of each test tube, and how you explained why you though your hypothesis would occur. Why do you think the results turned out how they did- it would be awesome to see a discussion explaining that next time.
