Hurumanu- Baloon chemistry

Aim: To see which chemical 
mix creates the most gas.

Hypothesis: (What do I think will happen)
I think the chemical mix with the most gas is the baking soda and the vinegar. I think that it is the mix because I have personally tried it, and in my opinion, I don't think that the other ones would be that strong.

Materials:

1.  Balloon 
2.  Bottle 
3. Funnel
4.  Yeast 
5.  Sugar 
6.  Baking Soda
7. Vinegar
8. Salt
9. Soda

Steps:

1.  Grab a bottle, make sure it is empty and dry. 
2.  Grab a Funnel and a balloon. 
3.  Then Get the first two ingredients, Yeast and Sugar.  
4.  Pour 2 tsp of the yeast and 1 tsp of sugar, make sure to pour it one at a time. 
5.  Then wait for it to rise. 
6. ~Next Experiment~ Repeat the first two steps, this time grab some baking soda and vinegar. 
7. Pour in 3 tsp of Baking Soda in the balloon and 1/2 half cup of Vinegar in the bottle.
8. Wait for the the gas to come up. 
9. ~Next Experiment~ Repeat the first two steps, this time grab some salt and soda. 
10. Pour in 3 tsp of salt in a balloon, and 1/2 half cup of soda.
11. Like the other experiments wait for the gas to go up. 

Findings:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 3 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	10.6cm	5.1cm	5.5cm
Bubbles	Medium Amount of Bubbles	Medium Amount of Bubbles	Large amount of Bubbles

Conclusion:

In the first mix (Bottle 1) we used 2 tsp of yeast and 1 tsp of sugar, in that we also used warm water to dissolve the mix. It took a really long time for the balloon to go up. It also made layers, one layer was with the yeast and sugar the second was with the water and the last was with the bubbles. Throughout it had made a layer were it was brownish coloured, it looked fluffy and it had a lot of bubbles. But the balloon didn't actually go up for our group.

In the second mix (Bottle 2) we used 3 tsp of baking soda and 1/2 half of vinegar. We first put the baking soda in the balloon it was really hard to put it on the funnel if it is wet, that is why we just put it in the balloon. So then we put the vinegar in the bottle. Lastly we put the balloon in the bottle held the balloon up so as the baking soda would fall out. The gas went up fast and filled the balloon up, it was really big. 

In the last mix (Bottle 3), here we used 3 tsp of salt and 1/2 cup of soda. The process is similar to the second mix, here we again put the salt in the balloon and the soda in the bottle. Then we again put it in the bottle and held it up for the salt to fall in the bottle. It wasn't as fast as the second mix but it still blew up the balloon. 

Rainbow experiment

Hurumanu - Rainbow Paper

Aim: To separate colours by using the process of chromatography.

Definition: Chromatography is a method of separating out materials from a mixture.

Eg. blood, ink, drugs,

Scenario

A crime has been committed. The police have a signed cheque and a letter from the same crime scene but it seems like the handwriting is different. They have 3 suspects but not enough evidence. They need to know if the letter and the cheque were written by the same person.

How do they tell if the pens used for both of these pieces of evidence are the same?

Rainbow paper

Materials:

1. Cup 

2. Felt Pens

3. Chromatography Paper

Process:

 1: Grab a chromatography paper and cup

Step 2: Choose 2 coloured felts (dark colours)

Step 3: Use a pencil and a ruler and mark a line on the chromatography paper where it 1cm is

Step 4: Put colours on your chromatography paper

Step 5: Then put it in your cup that is filled with water

Step 6: Then wait

Conclusion: What have I learnt from this experiment?

Maths this term

The term is coming to an end so I thought it would be a good Idea if I could make a slide to show you what we did this term in maths. I don't remember most of the stuff we did because we had worked a lot but I have tried to remember so here is the slide:

Adding and subtracting integers, decimals and fractions

From the title you already know what we did for maths. If you can't see it we were learning how to add and subtract integers, decimals and fractions. We had done a lot of work and as usual I had finished it and it was easy. I'd worked super hard on this. Anyway here is the slide of the work :

Place Value, Rounding, Estimating and Ordering

This work is Tuesday work. I know that it is Wednesday but I wasn't here and I was super sick so I couldn't do it on my computer. Anyways as you can tell from the title my work was about place value, rounding, estimating and ordering. This work was hard but somehow I still did it and got it all right. We had to do a whole page but we didn't have to do it all only the ones that we know.

Now as usual here is my slide go to the last slide to see my work:

Story boarding for art

Today in art we went to the next step of the stop motion. We had to choose what the story based is going to be what I mean is, is the characters made out of clay, is the story going to be made on the whiteboard or is the characters going to be made of object (shell, rubbish or etc). The next step was what the story was going to be based on, our story was based on caring. Then we brainstormed the whole story on a storyboard.

On the storyboard we had to put the scenery in and the characters. At the bottom was space for us to put down what was going on in that part of the story. We had each other choose what they wanted to do. Alliah chose to do the drawing, Lyan chose to do the writing, Jolly Rose chose to help us with the drawings by just putting some extra effect and I chose to describe to Alliah what the scene was going to look like.

Our story was about a grandmother who meets her granddaughter Wairua and then they grow a awesome bond with each other than she finds out she has cancer the granddaughter would be with her all the time. Then a few years later she died, her dying wish was for Wairua to graduate. Wairua promised her so she worked hard to get into college and then she made it. A lot of concentration went into her work then she finally made it. 

Then she grew older and had the same relation ship with her grandson and the same thing happened over and over again. The main thing about the story is that the grandchildren have cared for the elders and loved them till the day they died.

Here is the work we had done and see how well Alliah had drawn:

Science

Aim: To learn the names of 10 household chemicals and identify if they are a solid, liquid or a gas.

Definitions:

1. Element; A single form of a chemical 
2. Compound: A mixture made up of 2 or more elements
3. Reaction: A process in which chemicals mix together to form a new substance.
4. Mixture: When two or more elements are mixed together.

3.     Sugar
4.     Vinegar
5.     Lemonade bubbles
6.     Onion gas
7.     Baking soda
8.     Milk
9.     Cornflour (starch)
10.     Banana

Steps:

1. Name the chemicals
2. Research
3.Put the name of the chemical on the chart
4.What you have learned this lesson

Repeat the steps for all the chemicals.

Task 1: Put the 10 chemicals in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.

Name	Chemical	Image	Solid/Liquid/Gas
Salt Lemon juice Sugar Vinegar Lemonade bubbles Onion gas Baking soda Milk Cornflour Banana	Sodium Chloride Citric Acid Lactose Acetic Acid Carbon dioxide Syn-ropanethaial-s-oxid sodium hydrgen carbonate Magnesium Hydroxide Centaurea cyanus Isoamyl acetate		Solid Liquid Solid Liquid Liquid Gas Solid Liquid Solid Solid

CONCLUSION: ( WHAT DID YOU LEARN OR SEE)

In conclusion with this work I know what these home products are called in chemical and if they are solid, liquid and gas. Also what they look like. I know what most of them are. I know how to make an awesome blog post. I had lots of fun in science. I know how to correctly set up a blog post. I know most of the chemical names. I know where to go for science. I know what I need to do when we have done the experiments.

Integers

This weeks work was the same as last week but it was adding and subtracting tempter. So we had done a lot of work with this. It was really easy, we had learned a lot with these work. Some how I had finished all of it and I understand how tempter work. 

Here is the work we did:



Go to slide 3 to see what I did this week.
