Explanation writing!

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!


Trees

Trees are a special to our environment because they provide us food aka fruit, and  it is healthy for us  and it makes us happy.

How do Trees give us oxygen?

Like other plants tree’s have tiny little bright green chemical factories. These are able to use the energy of the sunlight to transform carbon dioxide and water into chemical compounds such as sugars. Oxygen is a by-product of the chemical reactions. Which makes the oxygen without it we wouldn’t survive.



How do trees eat and what do they eat?

All tree’s eat compost and sometimes even horse manure!
The drink rain water mostly but sometimes from us if we water them. Trees eat it by sucking it up from their roots deep deep down in the soil.


Trees trunks  

a trees trunk which is the bark and the inside layer of a tree has 5 layers in its trunk Theses layers are bark,cambium,sapwood,heartwood and pith.



Why do we need trees?

We all need trees to survive if we didn’t have any plants or trees we probably wouldn't last very long, because we wouldn’t be able to breath and breathing is very important!
also tree’s look amazing when they have flowers on them, they are fun to climb too!
So as you can see trees are very important.


What are deciduous and evergreen trees?

Deciduous trees

Deciduous trees leaves fall and have many different colored leaves and also different shapes they look beautiful when they fall although it is hard work raking them up.

Ever green trees

Ever green trees leaves never fall off they always stay on the branch. Evergreen trees don’t turn different colours and their leaves are sharp and pointy.
The good thing about them is you don’t have to rake the leaves.


In the end we all know that trees are very important and that they provide us fruit and oxygen that runs through the leafs and pushes out the oxygen.And that it sucks in the bad stuff carbon dioxide in.
And we all know what deciduous and evergreen trees are.

Why do we need sleep
we all need to sleep if we/you don’t sleep
we could die or get sick all animals and people
sleep to get healthy, strong and for our brains to
work. What do you think will happen if we don’t?
sleep gives your body a rest and allows it to
prepare for the next day ahead. Sleep also gives your brain to sort out things. Scientists aren’t exactly sure what kinds of organizing your brain well you sleep?. but they think sleep might give you
the time when the brain sorts and stores information,replaces chemicals, and solve problems

  • skipping 1 nights sleep
      makes a person cranky
       and clumsy.

  • After 2 nights of sleep, a person will have
    problems thinking and doing things his or
    her brain and body can’t do their tasks nearly
    as well.
 
  • after 5 night without sleep a person will
    hallucinate it means seeing things
   that aren’t actually there

  • eventually it becomes impossible for the brain to give its directions to the rest  of the body
     without sleep the brain needs to spend time
     in bed and catch its ZZZ’s

most  kids of the age of 5 and 12 are somewhere in
between 10 or 11 hours of sleep.Some kids might need more and some need less it depends on the kid.

Snoring is a common problem that can happen anyone young or old snoring happens when a person can’t move air freely through his or her nose
and mouth during sleep.

Questions
  • who invented time?          
  • how come when we go
to different countries they have a
different  time zone?
  • why is the day 24 hours long


Most students don’t like school, but when it comes to learning time… well that's a different  matter because when you learn to tell time you can keep an eye on the time whether its knowing when their  soccer game starts or something like that.

Who invented time

Time wasn’t really invented. After all, it’s always been around since… well… the beginning of time! Some people think of it as a dimension that helps to order our lives.

How come when we go to countries they have different time zones?

The Earth spins on an imaginary pole called its “axis.” Every 24 hours, the Earth makes a complete rotation — or one full turn — on its axis. We call each full turn a day. Imagine shining a flashlight at a globe. Only part of the globe would receive light, while the opposite side of the globe would be dark. As the Earth rotates, different parts of the Earth receive sunlight or darkness, giving us day and night.

why is the day 24 hours long?

Our 24-hour day comes from the ancient Egyptians who divided day-time into 10 hours they measured with devices such as shadow clocks, and added a twilight hour at the beginning and another one at the end of the daytime, says Lomb. "Night-time was divided in 12 hours, based on the observations of stars.

HOW TO GENERATE POWER

A generator turns the force of moving water and a hydro plant takes the force and creates electricity. a bolt of lightning can power 100 powerful lamps for a whole day or make a couple of hundred thousand slices of toast!

WHAT IS ELECTRICITY?

Electricity is a type of energy. If electricity gathers in one place, it as known static energy. The word static means something that does not move. Energy that's move to one place to another is called current energy.

WHAT IS STATIC ELECTRICITY?

Static electricity is when you rub something together like when you rub a balloon against your jumper 20 or 30 times, then the balloon will stick to you. this happens because rubbing the balloon against your jumper gives it a electric charge which is a small amount of electricity. The charge sticks to your jumper like a magnet because, the jumper has an opposite electric charge.

For electricity to work you would need to have a circuit. A circuit is a closed loop where electricity flow over and over.
