Corrosion - Science

What are you investigating? I'm investigating about what gonna happen to the nail coated with nail polish, magnesium, calcium chloride, saltwater, water, and oil. To see what gonna happen after you leave a minute

what do you think will happen? I think the nail gonna be rust

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

Observation:
- Nail coated nail polish
The nail was rusty at the top and the part with coated is not.
-  Nail coated oil
The nail was not rusty and it's still the same.
- Nail coated Water
The nail water very rusty
- Nail coated Calcium chloride
The nail

  1. Great Work Sheen! I really like how you have shown multiple pictures of the experiment. Did you expect all of the nails to rust? why do you think some of them were okay and didn't rust? Next time, I would like to see you explaining why you think things happened.
