Rust Task

Fast Rust Task
Rust

Walt: Write something that is about rust.
Task
Work on this Doc together with a partner.

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


Write a brief paragraph explaining the rusting process (why rusting occurs)
Metal can rust just by leaving it there. Do you want to know why it has rust? Well we have a new and shiny piece of metal and I do nothing with it. If the sun is hot it can reach the metal and burn the metal and the metal with rust. So that is a chemical change and that is how it rust the steel. 2. The iron surface of the nail reacts

with the oxygen mixed in the

water. It forms iron oxide.

3. Iron oxide reacts with the water.

It forms hydrated iron oxide –

the red stuff we call “rust”.

4. This process continues until

all the iron is eaten up.


How could you prevent something from rusting?
You can paint it with any kind of paint that you have or buy

You can put oil on it to prevent it from rusting

You can also spray on wax to prevent it from also rusting and keep it out of the water out of oxigen if you can and salt so it doesn't rust again



Write 3 sentences explaining something new you’ve learned from this reading.
That how rust can eat steel and rust is also stronger than steel but can crumble if you touch it .And also did you know that rust comes from water that hits the steel it start’s to rust
