Write a brief paragraph explaining the rusting process (why rusting occurs)
When oxygen from the air mixes with water and is placed on an iron surface. Slowly the iron reacts with the oxygen mixed with water therefore creating iron oxide. When Iron oxide mixes with the water it creates hydrated Iron oxide also known as (Rust).
Fact: When you add table salt/sodium chloride to this process the reaction will move a lot faster. You don’t have to add salt it will just help if you wanted to speed up your process.

How could you prevent something from rusting?
If you wanted to protect iron from getting rusted some things you could use is oil, Zinc/Zn or paint. Oil can help because when coated over iron it stops oxygen from getting in. Another way is by galvanising. This means to coat Zinc over iron and only the zinc will be affected but you can easily wash it of. You could also use a coating of paint to stop water from getting into cracks to stop or to slow down the rusting process.

Write 3 sentences explaining something new you’ve learned from this reading.
One thing I learnt during my reading was the process of how rusting works. Another thing I learnt was the three ingredients used to make rust, they are air, oxygen and iron. Greater amounts of rust can be found in different environments. e.g There is a greater amount of rust near the sea.
