Baking Soda (Sodium Bicarbonate) plus vinegar produces Carbon Dioxide (CO2) plus water.
Question: What produces more Carbon Dioxide (CO2) in this reaction? A mixture of a 2 TBS of baking soda and 1/4 cup of vinegar OR a 1 TBS of baking soda mixed with 1/2 cup of vinegar?
Hypothesis: A mixture with more vinegar than baking soda produces more Carbon Dioxide (CO2)
Procedure:Detail steps so anyone can reproduce this at school or home

The Science behind it
The reaction between baking soda (Sodium Bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas.
The carbon dioxide escapes the solution as bubbles. The bubbles are lighter than the vinegar, so the carbon dioxide collects inside the closed container (sandwich bag or balloon).

Conclusions
In conclusion our hypothesis was correct: a greater amount of vinegar produces a larger reaction.
