Fast Rust Task
Task
Work on this Doc together with a partner.
What 3 ingredients are needed for rust to occur.
Steal | Oxygen | Salt water |
Write a brief paragraph explaining the rusting process (why rusting occurs)
When the oxygen from the air mixes with the water and goes onto the surface of the iron nail it reacts with the oxygen that is mixed with the water it makes iron oxide, when the iron oxide reacts with the water it becomes, hydrated iron oxide, which forms into the red stuff that we know called rust, this process continues until the whole thing rusts |
How could you prevent something from rusting?
You can use paint to stop the rust, because it puts a layer between the steal and the iron oxide, that’s why they use it for the harbor bridge, but you can also use oil which will keep rust of bike chains |
Write 3 sentences explaining something new you’ve learned from this reading.
Something new that I read from the text was that the harbor bridge uses 3 layers of paint just to keep the steel from rusting. I also learnt how steel rusts, it is because of the water and the oxygen that mixes together. The last thing is that, i now know that rust can be slowed down if you use a couple layers of paint |
Write down any new words you found in Fast Rust or the article about rust. Make sure you learn what the word means and write down a definition you understand for each new word.
Word | Definition |
Corrosion | A breaking down of materials due to a chemical action like rusting. |
compound | A combination of two elements combined to make 2 elements |
rate | The speed at what something happens |
Sacrificial | For something to be used up or destroyed in fulfilling a purpose or function |
Alloy | Any type of metal that is mixed with a chemical to make it stronger |
Decays | Something that with some time will slowly break down until it is all gone |
Galvanizing | Covering something with zinc to protect it from rusting |
Zinc | This thing is used on metal because It has strong anticorrosive properties and bonds well with other metals |
Molecules | A group of atoms formed together |
Iron oxide | This is a chemical that is mixed with metal and oxygen |
Today in reading we read a book about rust, then we did this task where we had to answer some question, then write down words and write the definition of the word. overall this task was some what hard, but fun to do
