Learning how to read scientific reports

Kia ora

We are learning how to read and write scientific reports. We have been doing experiments and writing about them. This is a reading activity we did. We had to be able to match a thesis with its hypothesis.

We are learning how to understand the structure and language of a report about a scientific experiment #3 Understanding that a hypothesis is a brainy prediction based on what you already know.
In this exercise you need to match a thesis with its hypothesis.  Use the ‘Fill tool’ to colour code the matching ideas.
                               Thesis                                                                      Hypothesis
I know this……                                                                         So therefore if I do this I think this will happen…
I know that a puddle of water is a small amount of water lying (usually) on the ground. I know that water is a substance which is found on our planet and that it can exist as a solid (ice), liquid or a gas (water vapour). I know that the main reason water changes from one state to another on Earth is because of  temperature -heat or cold. On Earth a sunny day is when there are no clouds, the sky is blue and the temperature is usually warm or hot.
I predict that when I mix vinegar and baking soda together that a chemical reaction will occur and that I will be able to notice this. I might feel hotness or coldness, notice smoke or bubbles, smell something, hear some kind of noise or  find that the taste or texture of the foods has changed.
I know that heavy things usually sink and light things float. However, container ships are heavy but they still float so there must be more things that have an effect on floating than just weight. Blutack is a squishy material that is quite light. It usually comes as a wide, flat strip but you can shape it into a round ball, a sausage shape, an O shape etc or you could flatten it out into a thin, wide shape like a leaf or saucer. Leaves usually float and ships look a little like a leaf shape.
I predict that when I take an ice cube out of a freezer it will begin to change back into liquid water (this is called melting) because it will no longer be colder than 0 degrees centigrade.
I know that an ice cube is water which is frozen. I know that that liquid water freezes into ice when the temperature reaches 0 degrees centigrade. An ice cube will stay an ice cube as long as it stays in a freezer.
I predict that if I make a puddle of water somewhere on the playground on a hot, dry day that the puddle will dry up and disappear quite quickly.
I know that everything we eat is made up of different kinds of chemicals.Sometimes when you mix different chemicals together they react with each other in different ways and the substances will do things that they didn’t do before (chemical reaction) and become different to what they were like before (chemical change). You will be able to notice things happening by using your 5 senses to  listen, smell, feel, look at and sometimes taste what is going on. I know that vinegar and baking soda are both food substances and I learned that they are chemically different
I predict that if I take some ice cubes out of a freezer and wrap them in different materials, I will find that one material will keep the ice cube frozen for longer than the others. This material would then have proven itself to be the best insulator.
I know that liquid water changes into a solid (ice) when the temperature reaches 0 degrees centigrade. I know that a freezer will keep water solid because a freezer’s job is to keep food at a temperature just below 0 degrees centigrade.
We are going to use Bluetack as our material. We will use the same amount of Blutack to make three different shapes. One will be a straight, rectangular strip of Blutack, one will be a compact, round ball and the third will be a rounded  saucer shape like a boat. We predict that at least one of these will float.
I know that insulators are materials that can be used to protect yourself from too much heat or cold. When we put clothes on because we are cold, the clothes are insulators which help our bodies stay warm. If you put insulating material like Pink Batts in the ceiling of your house, in the winter the Batts help keep warm air inside the house. In the summer, The Pink Batts help stop hot air coming into the house so they help to keep us cool. Many  food containers like Thermos flasks and Chilly Bins are made out of insulating materials to keep food hot or cold.
I predict that when I put some liquid water into a freezer it will change from a liquid state into a solid state (ice) because the temperature in the freezer will be below 0 degrees centigrade.

Our science experiments

We have been doing science experiments in preparation for the science fair. Here is a photo of one of our experiments.
We tried to make a teabag fly.

Scientific writing

Kia ora

We are learning how to read and write scientific reports. We have been doing experiments and writing about them. This is a reading activity we did. We had to be able to match a title for a report with a wondering question.

Freezing Water.
What will happen when you mix vinegar and baking soda?
Floating and Sinking.
What will happen to an ice cube if you take it out of the freezer?
Kitchen Chemistry.
Which materials make the best insulators?
Disappearing Water.
What happens when you put a container of water into a freezer?
Keep Your Cool.
What will happen to a puddle of water on a hot day?
Ice Cube Experiment.
Does Blutack float?

Learning Journey

This is my learning journey master with all my maths,spelling and Reading. With all my grades,levels and stages from term one. This term I'm going to a new school called Bays Water Primary in Auckland and I'll be coming back to Ohaeawai next term. when I come back I want to be at stage six for maths and list six on spelling then the lucky last level 11.5-12.5 in reading.

Anzac puppy

This week we have been learning how to make a Storyboard on a website called Storyboard That. We based it on a book called The Anzac Puppy. We had to choose two verbs, two nouns and two adjectives and write the meanings. We also got to put photos in that relate to the word.
This is my storyboard. I liked doing this because it's good to learn new words and you get to choose your pictures and change them the way that you like.

Earth Dragon

This week we were learning how to write myths for a strange thing in the world. My one is about volcanic eruptions.
Earth Dragon

When the world was young on the planet Earth there was a rugged landscape with many huge mountains and dusty deserts. The mountains were all bulgy, shaky, rumbly and grumbly. It was as hot as an oven.In a dark, hot place lived a fierce and greedy dragon called the Earth dragon. He was powerful, spiky and red and orange. He had claws sharper than a needle, a narrow face and he dug tunnels under the Earth. He lived in the Earth's crust and ate all the smoking hot rocks and soil.
One day he got so greedy he ended up with an enormous tummy ache. He started moaning, groaning, whining, farting, burping and rolling all around. He was breathing and farting out smoke in all directions. All of sudden he did an enormous gigantic spew. Vomit spat out of the top of the mountain he was under like a fountain. It dribbled down the mountainside like red icing.
And that is why we still get volcanic eruptions. Because the dragon never stops being greedy and eating rocks and soil.

The minotaur

we have been learning about the minotaur and the nine young youths
Pleading a Cause - Persuasive Writing       

Pretend you are the King of Athens.  Write a letter to King Minos, pleading for the lives of the youths who are to be fed to the Minotaur.
Give at least 3 reasons why their lives should be spared.
Remember to write a conclusion at the end to link your reasons together.
Dear King Minos,
I am writing to you about the fate of the nine doomed youths.  I plead for their release on the grounds that:

The first reason is that many young lives have been wasted for years and I can not bear to lose more.

The second reason is because they have plenty more time in their lives to become warriors and protect the world.

My third reason is that we are running out of people in the city and there are no more young people in the city if you eat the nine young youths.
My conclusion is that you should not eat the youths as one day we will have no more people for you to eat.
Yours faithfully,
King of Athens
