carbon dioxide.

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

Hypothesis: (What do I think will happen) I think that the vinegar will make more gas. The balloons will blow up because the gases make carbon dioxide.


Materials:

1.  balloon
2.  bottle 
3.  salt
4.  baking soda
5.  vinegar 
6.  soda water

Steps:

1.   get the two bottles and two ballons.
2.  get the vinegar and soda into two different bottles.
3.  get the ballon and put the baking soda or salt.
4.  attach it to the bottle.
5.  tip the baking soda from the balloon to the bottle
6.   now you can watch and take photos. Have fun.

My images:

	Balloon 1 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)
Balloon Size (cm)	4cm	3cm
Bubbles (small, medium, large)	the bubbles there so small	the bubbles there so small even smaller than the one with vinegar

 When baking soda and a cup of vinegar is mixed it creates bubbles and when bubbles are made it can make carbon dioxide. This is the same with salt. when you add soda and salt the same thing happens. It creates carbon dioxide.
