A couple weeks ago we were given the task to draw a diagram of how green house gases work. This is my diagram. Enjoy!
Separating mixtures is when you take all the elements in a mixture apart. There are many methods we can use to separate the elements in a mixture. For example if you have clumps of dirt in a glass of water you can put it through a filter to get some of the dirt out. Another method is evaporation. This is when a liquid changes to a gas. So you could put you dirty water over a very hot flame and over time it will evaporate and turn to a gas.
Today (The 18th of July) 5/6B went into the science lab to start conducting their fair test and rusting project. This is where we work in partners to try and find a way to prevent rusting. My partner and I are using 3 different types of oil.
We are using our knowledge of the 4 states of matter to conduct our experiments. My partner and I soaked 3 nails in the 3 different types of oil for just over 2 hours on then put them in salty water to see if the water had any effect.
The file POE has my prediction attached.

In term 2 the year 5/6 did their integrated unit on ‘Chemical Change’. So every week 2 scientists from GTAC came into Moonee Ponds Primary school to teach us about changing state, the 4 states of matter and much, much more! I enjoyed this unit very much and I believe I benefited well from it.
3 facts I learnt were:
I learnt many things but here are some of my favorites:
I learnt that the change from a gas to a liquid is called condensation. So say you just had a shower and you didn’t have the fan on so there is a lot of steam in the room. Then the steam hits the mirror and it will go from being hot to being cold. So it will turn into a liquid.
Another thing I learn’t was the interests of gas particles. Gas particles stay a fair way away from each other. They bounce of the walls and of each other when they come into contact with them. When the particles get heated up they move faster and when they get cooled down they move slower.
Another thing I learnt is that a solid can turn into a gas. That change is called sublimation.
2 understandings I now have:
I now understand that it is possible to go from a solid to a gas without going through the step of melting. I understand that that process is called sublimation. I first found sublimation quite weird and didn’t think it was possible but I found a example which explained everything: Dry Ice. Dry Ice does not melt when it is left in the sun, it turns into a gas.
Another understanding I know have is that scientists don’t use all 5 senses in the science lab. In the science lab you look to observe somethings like : color change, size change, shape change, ect. You use your ears to hear bubbling or loud noises or nothing at all. You use hands to feel if something has gone from smooth to rough or vice-verse. And you use your nose to waft of a potion or something similar. You don’t taste anything in case there are dangerous chemicals in it or such.
1 question I still have:
I would like to know if fish would be able to survive on the moon? I would like to know this because I believe there is hydrogen in outer space and in H2O there is Hydrogen and oxygen but we all know fish can’t breathe in oxygen. So I started to wonder weather they would be able to live in outer space and I would like to find out in the future.
What were the most important things I learnt were:
I think the most important things I learnt were the names of the changing state processes.(Melting, Freezing, Evaporation, Condensation and Sublimation) I believe these will help me throughout life so I can explain the changes of state I observe. This will help me in my P.O.E charts so I can have a good explanation at the end.
How did I learn it:
I learnt them by listening to the scientists from GTAC explain it to me and to see how they all worked. I found out that when you make pop-corn the kernel evaporates because the inside of the kernel is water. So when the kernel gets hot the water inside starts to boil until finally there is so much gas inside the kernel that it has to pop.
What am I going to do with what I learnt:
I am going to use this information in the future because I dream of becoming a scientist for GTAC. This is a dream because I quite enjoyed our science unit and would like to do more of it in the future.
Special thanks to:
I would like to say thanks to GTAC for sending us Maria, Jacinta and Chris to teach us about the 4 states of matter and changing state.

This term the year 5/6 at Moonee ponds primary school studied and learnt about, the 3 levels of government, the road to federation and issues in Australia. With our issues we wrote a letter to whom it concerned, for example I am writing to Mr.G.Hunter (the environment minister) about the rain forest cutting in Tasmania.
3 Things I remember:
1.The fact that all of the states in Australia sends many numbers a of representatives an d the territories (Northern territory and Canberra) only send 2 representatives for each house!
2 I found it surprising when I found out that W.A (Western Australia) and Queensland were not always part of the Australian commonwealth. This means that they didn’t have a government and they didn’t follow the same rules as the rest of the country.
3 I found it interesting when I was on my own working on the rain forests in Tasmania. I found out that some of the trees in there are over 5000 years old! This i found very surprising because the minister of Tasmania wants to cut these trees down! 🙁
2 Understandings I now have:
1 I understand that every one (over the age of 18) votes for a minister. That minister has to contribute peoples ideas to parliament. That way everyone gets heard through one voice.
2 I understand that there is a minister for pretty much everything. There’s one for education, environment, health, welfare, ect.
1 Question or Wondering I still have:
1 Are they going to stop the rain forest cutting in Tasmania?
What is the most important thing I learnt?:
1 The most important thing I learnt is that parliament and whose in charge is a big fuss for sum people because they want someone they trust to be in charge and if they don’t get who they voted for, there will be lots of arguments through out the country.
How did I learn it?:
1 I learnt it through ‘Behind the news’ a program that the year 6’s in my class use for a homework assignment.
What am I going to do with it?:
1 I am going to use it in the future so I can vote for the right person responsibly. 🙂
I loved working on this. We had to find information and put it in one note using our note taking skills. After-wards we had to put it in our own words (Road to federation post 1). Then we had to get in to groups of 3 (James, Madeline and I). And this is what we made.
Australia started of with 6 colonies: Western Australia, South Australia, Tasmania, Queensland, New South Wales and Victoria. The main laws from all the colonies were made by the British rulers back in the United Kingdom.
In 1872 telegraphs (A type of mail) linked all the colonies and the idea of being Australian was celebrated through out Australia in songs and many poems. But Western Australia was not so happy about this.
Western Australia ( W.A) was not always a part of the Australian Commonwealth? It means they did not follow all of the same rules. They didn’t think voting for a government/prime minister was the best thing for them.
Western Australia did join the commonwealth though. They joined the commonwealth because when they had their gold rush all the people from the other colonies came, so after spending so much time socializing with people from other colonies they decided to join the commonwealth.
But before all this, in 1898, a referendum took place so that people in the nations could vote on the ruler. Queensland and Western Australia did not vote or get in on the action. Have you heard about Edmund Barton and the others? Lets learn about them now.
Henry Parkes was the premier of New south wales. This means he was the first to rule New south wales. He was the ruler of New South Wales 5 times and one of the most prominent men in parlerment. In October 1889 in a meeting called Tenterfield Address he asked for the colonies to ‘unite and create a great national government for all Australia’.
Lord Hopetoun was the first governor general. This means he was the chief representative of the Crown in a Commonwealth country of which the British monarch is head of state.
Alfred Deaken was the colonial politician. This means he was a politician from a certain colony.
In Australia we have quite a few different types of government ; but in other countries’ s its different…….
First of all there is democracy. a democracy is a country where the people elect the political party they want to rule. So elections will be held and the head of the winning party becomes government.
Second of there is Anarchy. Anarchy is when there is no government and there for no leader. This means the country is free to do what ever they want with no one to tell them not to.
Thirdly we can discus Communism. Communism is similar to a dictator. This means the governor plans and controls the whole econamy. There for they control everything so that there country is like one big family.
Now as our fourth topc lets talk about dictatorship. This means that that the army is incharge of every thing and the head of the army is the head of the country. Also the head of the army (the leader) is not voted to take charge of the country. Remember Hitler? He was the dictator of Germany for a long, long time. His army took over Germany and he stayed at the top and did not let people hold any elections to kick him out of his place.
In fith place there is the Federal Government. This means there is one main person in charge but they share there power with smaller governments across the country.
Now lets talk about Monarchy this is when there is a kind or queen in charge. So the royal family are the top leaders.
Do you no what a republic is? Its when the country has no king or no queen as there to leaders. That means there is government or a president in charge of the country.
Last of all there is the Totalitarian State. This means there is only 1 political party. There for the top of that party is automaticly the president or government.
I’m glad Austrailia has the mix it does and i want to expand my knowlage on dictatorship and comunism.
(house of Representatives)
We started of learning about the 3 levels of government. We had to read a text and high light key words and words we may not of understood. The text was about the history of parliament and the present. It also talked about what the 3 levels of government do. The local government takes care of local parks and health issues in their community. The state government takes care of public transport and the roads with help of the federal government. The federal government takes care of everything the whole of Australia. For example the boats. It the federal governments responsibility to talk to Indonesia about the boats.
Then we went on to talking about direct and indirect representation. Direct representation is when everyone is there. What would happen if everyone in Australia came together to talk about the law? All 26 million people? it would not work out would it? It would take to long, People would doze of others would get violent if they have opposite opinions. That’s why we live with indirect representation. We nominate a certain amount of people to go to represent us. They talk for us and share our idea’s.
Then last of all we talked about the 2 houses of parliament. The house of representatives and the senate house. We talked about how many representatives each state and each territory got to send to parliament for different reasons. All the states get to send different amounts of people because of the states population. The higher the population the more representatives get sent to parliament. And the territories only get to send 2 representatives because they have no state government. The federal government rules the territories so they only get to send 2 people to parliament for each house.
And so far that’s all 5/6B has learn’t about parliament.
