Practical Percentages L4 –

Task Description:

Today for maths we had to do these percentage problems, we are learning to calculate percentage and try and find the right answers to them. I found this quite challenging from my understanding, I watched the videos to see if they could help me sort of understand how these problems work and what I could do to solve them. I then tried to figure out the following questions with the information I got from the videos. I found the videos very helpful and I managed to complete this task and put it on my blog! I hope you enjoy going through the slides and seeing my answers to these equations!

Fast Rust

Fast Rust Task

What 3 ingredients are needed for rust to occur.

Iron  Water  Oxygen from the air 

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

Rust occurs when metal is exposed to air or water for a very long time.When oxygen which is the air we breathe mixes with water the iron surface of the metal then starts to react with the oxygen mixed with the water, this forms Iron oxide. Iron oxide reacts with the water, which then forms hydrated Iron Oxide, the reddish brownish stuff we call rust. This process continues until all the iron is eaten up. 

How could you prevent something from rusting?

You can protect metal from rust by, covering with paint, coating oil or even plastic, this helps prevent rust from metal, but if the metal were in water for example the harbor bridge which is located in New Zealand is made out of steel and is in salt water, The first half of steel is not in water. Therefore it gets coated with paint at least three times. But the bottom of the harbor bridge which is the other half of the steel has to get coated more than three times because of how it is easier and faster for the rust to process.

Write 3 sentences explaining something new you’ve learned from this reading.

I’ve learnt that the harbor bridge needs to be coated more than three times, and the rest of the steel which is at the bottom, needs to be coated more than three times. I also learnt that when metal or steel is exposed to air or water it slowly starts to react in a way that then turns into something called Iron Oxide, this then reacts with water becoming hydrated Iron Oxide. Which is what we call rust. Another thing I learnt was that steel rusts faster and slower in different environments, and that some steel could possibly take years to rust and others in a matter of days. 

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.
Alloy Something that makes the metal stronger and more unbreakable to corrosion.
Exposed When something is being seen by something/someone else.
Decays When something is dying slowly. 
Texture When something is slightly detailed and has a type of touch to it. 
Protection Something that has a shield that can protect itself. 
Unreactive Something that is not responsive. 
Coating Something that has a layer of paint or something.
Chemicals Something that can react to each other in a way or can have no response.
Stainless steel A steel that has no stain or mess on it

Year 7 Step up

Last week on Wednesday on the 18th of May, the year 8’s went to a leadership camp for three days. The year 7’s stayed at school and did something called a year 7 step up program while the year 8’s were gone. 


One of my favourite things about the year 7 step up was the puzzle art that we had to do with Miss Hill. She was the leader of the team Mighty Kiwi for the first rotation of the block and day. What we had to do was draw different types of colours on a puzzled paper we got given. Some were bird pieces and some were words. I was given words and it was easy to draw but I took my time on drawing so it looks nice. 


The year 7’s had a movie on Friday with popcorn in the middle and last block of school because the program for year 7 and 8 were ending. We were watching the movie Soul and Raya and the Last Dragon, quietly because it was a time to relax from all the fun we had and a time to remember. While the year 7’s were eating popcorn there was something at the bottom, curiosity struck me as I reached for the bottom and found 3 types of lollies at the bottom, there was a lollipop, and 2 small squared lollies. 


During these 3 days I was nervous of what we were doing while the year 8’s were gone but it was fun anyways because I got to hang out with different types of people and I also got to talk to them while trying to do participation type of activities. I didn’t enjoy it when we yelled at each other during the time we had to work together but we learnt from it at the end and worked together.
