Rust Task

Fast Rust Task

Walt: Walt: Synthesise information from multiple sources.
Success Criteria: I can make links between the multiple resources I access.
Task: Learning wh
Work on this Doc together with a partner.

What 3 ingredients are needed for rust to occur.
Oxygen from the air (O2)
Water (H2O)

Write a brief paragraph explaining the rusting process (why rusting occurs)

To make an iron or steel rust you will need oxygen, water and iron/steel to make it rust. Oxygen from air mixes with water. The iron surface of the nail reacts with the oxygen mixed in the water. It then forms iron oxide. Iron oxide reacts with water. It forms hydrated iron oxide, the red stuff we call rust. This process continues until it’s been eaten up.

How could you prevent something from rusting?
If a chain on a bicycle rust, putting on oil will make the bike work better and will protect the chain from rusting again.

Write 3 sentences explaining something new you’ve learned from this reading.
Something new I’ve learnt about was that iron, water, and oxygen makes iron rust. But using iron, water, and salt will make iron rust even faster. Using Zinc or paint to protect a iron will not make the iron rust.
This is last weeks reading task of how steel rust.
