SCIENCE PROJECT

Corrosion Experiment

Aim: To investigate the factors that cause rusting in iron

Equipment: Four test tubes, test tube rack, a bung, four iron nails, boiled water, tap water, salty water, cooking oil, calcium chloride

Method: 

1. Label four test tubes A-D and place in a test tube rack
2. Test tube Contents:
   A= Iron nail and tap water
   B= Iron nail and salty water
   C= Iron nail, boiled water, and oil
   D= Iron nail and calcium chloride. Sealed with a bung
3. Leave the test tubes undisturbed for at least three days

Observations: The nail in salt water and water get rusted and a little bit on magnesium but the oil one didn't get rust at all. 

What are you investigating?

Were investigating the factors that cause rusting in iron

What do you think will happen? (Hypothesis)

Maybe some of the Iron will get rust and turn to the color brown. In salt water, I think the nail will be clean and turn to color to silver 

What is corrosion?

Corrosion is when metals are exposed to the environment they can deteriorate, or break down, scientist call this process corrosion. Rust is the term used to describe the corrosion of iron
