Explanation Writing #2

We have been very busy learning about writing to explain in Room 18. We read through a story called "Animals and Migration" and looked at the way they structured their explanation and also the language features used to construct the text. This text helped us to get an idea of how an explanation piece should be written. Below are our explanation pieces. We incorporated our inquiry questions into our writing activity, so we have answered our inquiry questions and then written them into an explanation. Hope you enjoy them!

Why is the sky blue?

Have you ever wondered why the sky is blue?

What makes the sky blue is trillions of tiny tiny dust particles that roam in the earth’s atmosphere, day and night.But at sunset these particles scatter everywhere and that is why we began to see orange and yellow.It is the same for the morning when the sun rises you see yellow and orange.

That is why the sky is blue.

Why are cats scared of water?

Some people may think why are cats scared of water well actually not all cats feel the same way about taking a dip. There is one type of cat called the strikingly beautiful turkish van cat, this type of breed actually delights getting wet.
     types of cats that love water
there are a lot of breeds of cats that absolutely love taking baths or even going for a swim  here are a few of them…….
1. maine coon
2. norwegian forest cat
3. japanese bobtail
4. turkish van
5. savannah
and bengal
so keep in mind if your cat is one of these breeds than you can wash it they won’t run away.

Despite not enjoying a full immersion, many house cats are fascinated by water, dipping an exploring paw into the water bowl to scatter a few drops or running into the bathroom at the sound of a shower. As soon as they hear the bath or shower running they'll know to pounce in.

On the other hand, some big cats in the wild, especially those in hot, arid areas, regularly swim and bathe to stay cool or catch dinner. The Asian fishing cat is a skilled swimmer, with  webbed paws, that dives to catch its prey.

in conclusion not all cats are scared of water some breeds absolutely love water and enjoy having a dip. Remember if your cat was one of those breeds that were listed then they’ll enjoy having a wash.

The sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and humint (about 28%) carbon nitrogen and oxygen up to 1.5% and the other 0.5% is made up of small amounts of any other elements such as neon, iron,silicon,magnesium and sulfur

Most of the gas — about 72 percent — is hydrogen. Nuclear fusion converts hydrogen into other elements. The sun is also composed of about 26 percent helium and trace amounts of other elements — oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.
These elements are created in the sun's core, which makes up 25 percent of the sun. Gravitational forces create tremendous pressure and temperatures in the core. The temperature of the sun in this layer is about 27 million degrees F (15 million degrees C). Hydrogen atoms are compressed and fuse together, creating helium and a lot of energy. This process is called nuclear fusion.
The convection zone is the outermost layer of the sun's interior. It extends from about 125,000 miles (200,000 km) deep up to the visible surface or the sun's atmosphere. Temperatures cool in this zone, enough for heavier ions — such as carbon, nitrogen, oxygen, calcium and iron — to hold onto their electrons. This makes the material more opaque and traps heat, causing the plasma to boil or "convect."

What is frost?      

Frost is a deposit of small white crystals formed on the ground or other surfaces when the temperature falls below freezing.  

What causes frost?

Frost forms in much the same way as dew forms. Frost usually forms when a surface cools through loss of infrared radiation to a temperature which is colder than the dewpoint of air next to the surface and the temperature of that surface below freezing (32 deg f or o'deg.c). The source of this moisture is water vapor contained in the air.

Why Milk Is White In Colour:
Milk is made up of a protein called casein which is rich in calcium, which makes your bones strong. Casein along with the white - coloured fat present in the milk gives milk its colour.Milk is made up of about 87% water and 13% solids, such as fat and various protein.                

What milk REALLY has in it:
Everything you know about cow's milk and dairy is probably part of a Dairy industry MYTH. Cow's milk is an unhealthy fluid from diseased animals that contains a wide range of dangerous and disease-causing substances that have a cumulative negative effect on all who consume it.people who have just milked a cow should just put the milk into a bottle ready for someone to buy it, but instead they add things into it then take things out of the milk and add this and that and all sorts of things and then after all of that they take a few more things OUT of the cow's milk and THEN put it into the bottle, ready to be brought.

the pros and cons of milk:

pro: Milk is one-stop shopping for nutrition. It contains nearly all the basic nutrients that a growing child needs.con: some people can be allergic to milk and have something really bad done to them if they drink milk, for example: they could get a really bad headache, feel sick, and can even end up in hospital if its that serious.

How Milk Can Be Used:
milk can be made into milk powder which can be exported overseas. milk can be used in cooking, fonterra milk for school, and milk can be turned into butter and different types to chese.

         How Humans grow:

Humans start off as a seed inside our mother's stomach. Babies need the right nutrition to grow through the umbilical cord. A humans growth is regulated by a growth hormone which is found in the pituitary gland.


A balanced diet is necessary to help us grow from a baby to an adult. Like fruit, veggies, and lots of protein.

Do you know that many people think rugby was born in 1823 and the man who invented it is called
William webb ellis with fine disregard for the rules

various codes) as played in his time at rugby school, first took the ball in his arms and ran with it.
