Corrosion Experiment

SCIENCE
In science, we are investigating rusting.
Our aim is to investigate the factors that cause rusting in iron.

HYPOTHESIS
I think that the nail in the calcium chloride and water will rust the most and that oil would rust the least.

Corrosion is the process of corroding or being corroded or damage caused to metal, stone, or other materials by corrosion.

OBSERVATIONS
Saltwater rusted the most whereas oil rusted the least
  • Nail polish: Rusted at the top and the nail polish came off.
  • Oil: Didn't rust at all.
  • Saltwater: Rusted the most.
  • Calcium chloride + water: Hardly rusted.
  • Magnesium + water: Rusted a little bit. 

Left to right: Nail Polish+water, oil, saltwater, calcium chloride+water, magnesium+water

    I liked your good clear description of your experiment. Can you draw a conclusion about how to prevent rusting on iron and steel? Where is that knowledge used in the world around you?

    Hi Nelly, Great experiment set up! I really like how you included before and after pictures. Next time it would be great to see a conclusion and discussion- was your hypothesis correct (conclusion)? why was it happening (discussion)?

To support my learning I ask you to comment as follows:
1. Something positive - something you like about what I have shared.
2. Thoughtful - A sentence to let us know you actually read/watched or listened to what I had to say
3. Something thoughtful - how have you connected with my learning? Give me some ideas for next time or ask me a question.
