Fast Rust Task - W5T4

Fast Rust Task - With Alfa

Rust

Walt: Synthesize information from multiple resources.

Task

Work on this Doc together with a partner.

What 3 ingredients are needed for rust to occur.

Iron

Oxygen

Water

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

Oxygen from the air mixes with water. The iron surface of the nail reacts with the oxygen mixed in the water. It forms iron oxide. Iron oxide reacts with the water. It forms hydrated iron oxide - red stuff we call rust. This process continues until all the iron is eaten up.

How could you prevent something from rusting?

Use paint and alloys (mixes of metals). Another way of avoiding rust is using spray-on wax or oil coatings that the car companies sell. One alloy that could be used is stainless steel, which helps the the iron to last longer (rusts slower). Keep iron away from water and oxygen. 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.

We learnt that oxygen, air and water is what causes things to rust. Also we didn’t know that rust could be prevented by painting over the metal, using spray-on wax or oil coatings. All iron objects can be rusted if they are exposed by oxygen and water including trains, bikes (chains), skateboards (wheel bearings), house roof and many other things. One interesting fact that we found out was that the harbour bridge has the biggest paint job to prevent it from rusting.

Holiday Highlight Week 5

Hanging With My Cousins

It was the last week of the school holidays and for the last week I just chilled out with my cuzzies. From the left is Hector, Kristopher, Elijah, Me, Juliana and David on the right. We watched cartoons together on the couch. Hector, David and I walked to the G.I train station and caught a train to Sylvia Park. We also had a sleepover in the lounge which was awesome because we got to play xbox games and watch movies.

  
 

NIUEAN ZONE ATHLETICS

Saturday morning I jumped out of bed and travelled to Massey Park, where the Niuean Zone Athletics was held. When we arrived at the park we started off with marching. Then it was the four to six year olds that were running before, I ran the 100metre sprints.

It was my turn to race and I had butterflies in my stomach. “Take your marks, set GO!” The race official shouted. Sprinting off the start line I could hear my family cheering for me. “Go stevenson!” They cheered. As I approached the finish line I was greeted with a big hug from my nana. I came first and got rewarded with a blue ribbon. Running back to where I was sitting I showed my mum and she was proud. I waited for my next race, which was the 200metres and I won that heat too.  It was the finals and I came second in both of them and got a platinum medal. I also got a bronze medal for the eight to tens relays. This was an awesome time at the Niuean Zone Athletics, looks at the photos below.

 

MOVIES IN THE PARK

To end the last week of the school holidays, I drove to Pt. England Reserve to watch Wreck It Ralph. It was an outdoor cinema. This was my first time attending this type of event. Awesome was the way to describe watching a movie outdoors on a massive as screen.

I saw two of my friends named Zane and Janice. My mum and I sat next to Janice and her family, and Zane and his cousin  joined us. When the sun was gone and the moon was up the movie had finally started. It felt like a normal cinema at the movies except we had blankets and a picnic.

When the movie ended everybody clapped and made their way home.
