Balloon experiment

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

Hypothesis: (What do I think will happen)
I think that the baking soda and vinegar will create the most gas to fill the balloon and make it bigger than the other balloons. I think that because all of the experiments I have done with mixing these two ingredients has related in making a lot of gas.

Materials:

1.  Bottles
2.  Balloons
3.  Baking soda
4.  Soda water
5.  Salt
6.  1/2 cup measuring cup 
7. Yeast
8. Sugar
9. Funnel

Steps:

1. Grab your bottle, make sure it is empty and dry. 
2.  Grab you funnel and balloon.
3.  Get the first ingredients yeast and sugar.
4.  Pour 2 tsp of the yeast and 1 tsp of sugar, make sure to pour it in one at a time.
5. Then wait for it to rise. 
6.  For the next experiments do the same thing except with the salt and baking soda for the other 2 ingredients go into the balloon.  

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)	12.5cm	5.2cm	4.5cm
Bubbles	Small amount of bubbles.	Medium amount of bubbles	Large amount of bubbles.

Conclusion:

For science this week we did a science experiment were we had to see what chemical mix make the most gas to fill the balloon the most. Balloon one was baking soda and vinegar, the balloon rose fast and got pretty big but didn't get much bigger after. Balloon two was salt and soda water, this balloon rose pretty slow and didn't get very big. Balloon three was yeast and sugar, this balloon had to be started first as it took awhile to rise and made the smallest balloon. I  think if the yeast balloon had been given more time to work it might have been bigger that balloon two but a little smaller than balloon one.
