Hurumanu - Balloon chemistry

Hurumanu - Balloon chemistry

Aim: To see which chemical 
mix creates the most gas to blow up the balloon.

Hypothesis: From the start I had no clue what was going to happen because i don't really have experience with chemical.

Materials:

1. 1 spoon of sugar 
2.  2 spoons of yest
3.  balloon x3
4.  funnel
5.  hot water
6.  3 spoons of salt
7. 3 spoons of baking soda
8. half a cup of vinegar
9. half a cup of soda
10. 
    

Steps:

1. Get your bottle and put all your ingredients in using a funnel
2. poor hot water in. 
3. Then quickly put your balloon on the lip of the bottle. 
4. now wait for the magic to happen

My images:

Findings: I found out today that baking soda and vinegar blew the balloon up bigger and faster.

	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)	12 cm	9 cm	10 cm
Bubbles	Lots of bubbles		Not much bubbles

Conclusion: 
When the yeast and sugar were mixed together it was going very slow and from there I knew it wasn't going to go very far. In the end it blew up 10 cm I thought it was going to at lest get over 20.

Next was the salt soda at first It was going like medium speed I thought it would be the biggest. But after about 3 seconds it just stooped. It manged to retch 9 cm.   

Last it was the baking soda and vinegar, it started off fast there I knew it was going to be the biggest after about 10 to 15 seconds it stooped. It got 12 cm

Story board

Hi guys to day me and my group from art have made a story board sketch up. The sketch was about a story we made up. Here are some pictures. We also got some feedback from people.

Here is a picture of what we sketched. Sorry if you cant see.

Here is a picture of the feedback we got. Sorry if you cant see.

Next my group will use the feedback we have received to improve.  

C.I.P

For C.I.P this I had a choice of making jam, do some gardening or cleaning around the compost. I choose to do compost in it we picked up rubbish and flipped the compost around. Also today I had rugby academy were we played both league and union tackle. I haven't played in a long time so to play both sports again was  an amazing feeling. We were practising some moves we learnt last week. I had moari the teacher there is one of my favourite because of the fact that he is super funny, we had a partner and we spoke moari to them. What we were saying was an character we made up one describing word for it and a name. Here is what I wrote in moari Terā tētahi hawini
