Aim: To see mix creates the most gas.

Hypothesis: (What do I think will happen)    

what I think is going to happen  that is vinegar and baking soda is going to make most gas, because if you shaking the baking soda and vinegar then the gas will make more, and  if you put it together then the water will 
Materials:

1.  warm water 
2.  sugar 2 Tsp
3.  bottle X3
4.  funnel
5.   balloon X3
6. vinegar 2 tsp
7. baking soda 
8. soda 
9. yeast 2 tsp
10. salt
11. soda water 

Steps:

1.  first, get a bottle from the bag and get a balloon and funnel
2.  put sugar and 2 tsp yeast in the bottle
3.  put warm water in the bottle
4.  quickly put a balloon on
5. second, get other bottle and balloon and funnel
6.  put 2 tsp vinegar in the bottle and baking soda in the bottle
7. put warm water in the bottle then put balloon on
8. third get the other bottle and a balloon and funnel 
9. put soda and 2 tsp yeast in the bottle 
10. put warm water in the bottle 
11.  then put a balloon on the battle 

My images:

Findings: if you put baking soda and vinegar together then the balloon made fast be big, but not so many bubbles in the bottle. if you put salt and soda in the bottle then the balloon made big slowly also I have found out carbon dioxide effect can make a difference to how big are the balloon.

	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)	14.7 cm	8.6 cm	12.8 cm
Bubbles	small amount	small amount	large amount

Conclusion: 

• At balloon A we put 3 tsp baking soda, 1/2 cup vinegar in a bottle and we put warm water in there too.
• At balloon B we put 3 tsp salt, 1/2 cup soda and warm water in the other bottle
• At balloon C we put 2 tsp years, 1 tsp sugar and warm water put in another bottle 

At balloon A when we put a balloon on the bottle, the balloon was made balloon was so quickly also balloon A make big to 14.7 cm. At balloon B when we put a balloon on the bottle, the balloon was made big so slow and balloon B just make big to 8.6 cm. At balloon C when we put a balloon on the bottle, the balloon was made big slowly too but is faster then balloon B, also balloon C make big to 12.8 cm.

I have found out carbon dioxide effect can make a difference to how big are the balloon, also I have found out my hypothesis is correct, because my hypothesis is the only bigger one.
