Home chemistry 3.

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

Hypothesis: (What do I think will happen) 
I think that the vinegar and baking soda will make the bigger balloon.


Materials:

1.  Vinegar ½ cup
2. baking soda 3 tsp 
3.  salt 3 tsp
4. soda water ½ cup
5. yeast 2 tsp
6.  sugar 1 tsp
7. x 3 bottles
8. x 3 ballons
9. funnel 

Steps:

1.  get your bottles and balloons
2.  get your ingredients
3.  add ingredients
4. watch 

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

conclusion:

My hypothesis was correct that the baking soda and vinegar created the biggest balloon. It was really cool to see the baking soda go into the vinegar and fill up the ballon.

At the end of it, all the balloons were different coloured and they were all different sizes. The smallest was the salt and soda water was the smallest it is very interesting how different the size is. 

I learned that gas can fill a balloon. I also learnt that the largest balloon makes less amount of bubbles.
