Fast Rust Task

Walt: Synthesise information from multiple sources.
Work on this Doc together with a partner.

What 3 ingredients are needed for rust to occur.
Water
Oxygen
Iron

  • Write a brief paragraph explaining the rusting process (why rusting occurs)
When Oxygen from the air mixes with water, the iron surface reacts with the oxygen mixed into the water, forming iron oxide. Iron oxide reacts with the water. It forms hydrated iron oxide - red stuff we call (rust). It continues until the iron is gone. Only metals with iron in them can rust.

  • How could you prevent something from rusting?
If you want to protect iron from getting rusted things like oil and paint can help. Oil creates a surface that will stop any oxygen from getting in.  You could also use layers of paint to stop water from getting into the cracks and to slow down the process of rusting.

  • Write 3 sentences explaining something new you’ve learned from this reading.
I have learnt that rusting doesn’t just occur due to how old the iron is,  but due to the oxygen that surrounds the iron. I’ve also learnt how the process of rusting starts and what can help to prevent rusting from happening. Another thing I have learnt from this text is the main 3 things that make rust, Iron, Oxygen and water.
