question
where is the gas formed during the chemical reaction of vinegar and baking soda and how can we see this
Hypothesis
The gas is formed as bubbles inside the mixture
Equipment
baking soda , sultanas, container, vinegar, and measuring spoons
Method
The vinegar is poured into the container.
The baking soda is sprinkled in the container
The sultana are the added.
Observation
Bubbles formed when the baking soda and vinegar mixed.
The sultanas traveled to the top of vinegar and then down.This repeated until the bubbles disappeared
Explanation
The sultanas moved to the top because the bubbles of carbon dioxide formed under the sultanas and pushed them to the top. At the top the bubbles popped and released gas causing the sultanas to fall. This process repeated until there were no more bubbles this proves that gas is formed as bubbles inside the mixture

Question: Where is the gas formed during the chemical reaction of vinegar and baking soda and how we can see this.
Hypothesis: The gas is formed as bubbles inside the mixture.
Equipment: Baking Soda, Vinegar, Sultanas, Measuring Spoon and Containers.
Method:
1) The vinegar is poured into the container.
2) The sultanas are added.
3) The baking soda is sprinkled into the container.
Observation:
1) Bubbles are formed when the vinegar and baking soda is mixed.
2) The sultanas traveled to the top of the bubbles and then down.This is repeated until all the bubbles have diapered.

2) The sultanas traveled to the top of the bubbles and then down.This is repeated until all the bubbles have diapered.
Explanation: The sultanas moved to the top because of Carbon Dioxide formed under the sultanas and then pushed to the top.At the top the bubbles popped and released gas causing the sultanas to fall.This process is repeated until there is no more bubbles.
This Proves: The gas is formed as bubbles inside the mixture.P.S the the gas Carbon Dioxide, scientists call it CO2.

Question
Where is the gas formed and how can we see this during the chemical reaction of vinegar and baking soda?
Hypothesis
This gas is formed as bubbles inside the mixture.
Equipment
Baking soda
Vinegar
raisins/sultanas
measuring spoons
container
Method
1. The vinegar is poured into the container.
2. The baking soda is sprinkled in the vinegar.
3. The sultanas are added.
Observation
1. The bubbles formed when the baking soda and vinegar mixed.
2. The sultanas travelled to the top of the vinegar and then down. This repeated until the bubbles disappeared.
Explanation
The sultanas moved to the top because the bubbles of Co2 formed under the sultanas & pushed them to the top. At the top, the bubbles popped & released gas, causing the sultanas to fall. This process repeated until there were no more bubbles. This proves that when you mix baking soda and vinegar, the gas is formed as bubbles inside the mixture.

The New Library Opening
John Key Opening the Library
On Friday the 13th of March John Key came to the the school to open our new library. First the councillors had to go to the office to show the invited guests and the parents where to sit. After that we had to go inside and than we went outside of the new library.
First Mr Key cut the orange ribbon. Then the councillors followed John Key and some other people. He showed us the water fountain and then he uncovered a plaque and it said the day that the library was opened and by John Key
After that we went into the library. It was really cool. It was so amazing I could not believe it. First we had to show someone around the new library and then I got to have a look around.The intermediate people went on the computers.
After that the councillors had to go outside the stuffroom and we had afternoon tea with John Key and I got to shake his hand.That was the end of the cool as day with John Key and the opening of the new library.
I had so much fun I want something like that to happen again!!

My hair looks like a brown swirl of fresh melted chocolate.
My eyes are soft like a brown bears fur.
My smile is like a sparkling reflection by the water side.
