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

Hypothesis: (What do I think will happen)
I think that the vinegar and baking soda will make the balloon blow up the most because when you mix them the as rises so that's why I think that


Materials:

1. 3 Bottles
2. 3 Balloon
3. Baking soda 3 tsp
4.  Vinegar 1/2 a cup
5.  Salt 3 tsp
6.  Soda water 1/2 a cup
7. Yeast 2 tsp
8. Sugar 1 tsp
9. Warm Water
10. Funnel

Steps:

1.  Get 3 balloons and three bottles
2.  Add Yeast, Sugar and warm water in one bottle using the funnel. 
3.  Add vinegar and baking soda in another bottle using the funnel (but the baking soda in the balloon first)
4.  Add Salt and Soda water into a bottle using funnel.
5.  Put balloons on top of bottle.
6.  Wait for the results ( this my take unto an hour

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)	14.7 cm	8.6 cm	12.8 cm
Bubbles	Small amounts	Small amounts	Large amounts

Conclusion:

I have learnt that carbon dioxide affect can make a different to how big a balloon grows.

This is because the carbon dioxide make air that goes up and the balloon grows.

I have also learnt that when chemical react to each other it make carbon dioxide.

The yeast and sugar was the one that took the longest but still not the one that was the biggest balloon size. It was the one that had the most bubbles as there where lots of them.

The Baking soda and vinegar was the one that went up the quickest and the largest. But it had no bubbles at all.

The salt and soda water where the one with the smallest size and the least amount of bubbles.

I have found out that my hypothesis is correct because it was the bigger

BYE!
