Goodbye Term 1!

Hello people! Welcome to another blog post. The school holidays started just a week ago and I would just like to share what we did and how I felt about the first term. Well sit back and enjoy!

Term 1 was a stressful term since we were starting the year and we had a lot of tests. We did have a lot of activities including Athletics and Passion Projects and more.....

Maths:
For maths, our theme or what we were mainly focusing on was adding and subtracting, etc fractions, integers and decimals. It was a really fun thing to do and we also got to make DLO/Digital Learning. Also every Friday we got to play a very cool maths game called position 18, we had a challenge and we had to get the most wins, at the end of the term we would add up the scores and we would get an award. So the winners from this term were me, but there was another student who got the same score as me.


We didn't get to do much writing and for reading, we did some activities on a website called read works.

For other activities such as Wednesday activities you can see that all over my blog, all you so you see is search for it at the top left and type Tane Mahuta, the information will be there if you would like to see.

Happy Easter!

Hello, people! Welcome to another post, don't go past this post because this will be quick. Well, I Have to say have a Happy Easter. Though it may have past I hope you celebrated your Easter well and I hope you are having fun. Well, enjoy it while you can there is only 4 days till we are back to school. Anyways that is all I have to say, once again have a happy Easter and enjoy the rest of the holidays!

Home Chemistry: Hurumanu, Balloon 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. 

My images:

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 A) 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 B) 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 C), 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. 

Home Chemistry: 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. Chromatography paper

3. Felt Pens 

4. Water

5. Pencil

6. Ruler 

Process:

Step 1: Gather the following things: Chromatography Paper, pen ruler, felt pens.

Step 2:  Draw a 1cm line on the CHromatography Paper, with a pencil. 

Step 3: Draw 2 dots using felt pens on the Chromatography Paper. 

Step 4: Fold the paper, behind cup near the top of the water, to hold the paper.

Step 5: Teacher pours water, in the cup.

Step 6: Then wait for the colours to climb up the paper. 

Conclusion: What have I learnt from this experiment?

So we first got the Chromatography paper, drew a line one centimetre up and then got two felt pens, preferably a dark colour. Then we drew two dots on the line, but we made sure that they didn't touch. Then we put the paper on the cup, folded the top part so the water could only reach the end of the paper. Then we waited as the paper soaked up the water. But in our first try, it didn't work out because there was too much water. So I suggest if you're going to do this try pouring the water in first.
