Vagahau Niue

As you may have already known; this week is Niue language week. This week we are learning about the perspective of an author writing about the language week this week. While reading through some of the articles, I even got to learn a quote in Niue. 'Ko koe, ko au, ko tautolu, ko e tau Niue'. I was really amazed at how much the Niue language is very similar to the Tongan language.

Water Wise

Walt: I make sense of all information before, during and after reading by connecting it to myself, text I know and my world.
This week our task was to read a text set before starting this google presentation. In this activity we had to create a poster. In our poster we had to add images and text to explain the importance of water. Go to slide 7 to check out my poster.

FAST RUST

Fast Rust Task

Rust

Walt: synthesise information from multiple sources.

Task

Work on this Doc together with a partner.

What 3 ingredients are needed for rust to occur.

Metal

Oxygen from the air (O)

Water (H2O)

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

When some metals are exposed with water and oxygen, it forms rust. Rust is a type of corrosion. Rusting occurs when H2O (water) and O (oxygen) is in contact with iron or steel. The rusting process becomes faster when salty water or acid rain is applied.

                                                                                                        

How could you prevent something from rusting?

By preventing metal from rusting you can paint it or put a layer of oil or grease over the metal. It is a good idea to use this as a solution so that the oxygen could bounce off the metal instead of rusting it, depending on what kind of environment  the metal is in.

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

We learnt that the term corrosion is used to describe metal breaking down when it is exposed to the environment. We also learnt that rusting can be prevented when you either paint, grease/oil or a process called galvanizing. An example of galvanizing is when you put zinc and iron together, the zinc protects the iron but it sacrifices itself because zinc reacts more than the iron.

__________________________________________________________________________

In this task I learnt about rust and how metal can corrode. Rust is a type of corrosion, corrosion happens to metals when they are exposed with water and air for a long time. Rust slowly breaks down metals into other chemicals. Another name for rust is hydrated iron oxide.
