Conclusions
I conclude that my hypothesis was incorrect because collecting the carbon dioxide was not
successful in all of the experiments. It was the yeast combined with sugar and water that did
not work.
The first time I was only able to collect carbon dioxide from the Pepsi and not the yeast or the
chemical reaction with baking soda and vinegar. The second time I tried to collect carbon
dioxide from all three experiments, I was able to collect carbon dioxide from the Pepsi and the
chemical reaction.
The first time I tried the experiments, my Mom helped me and the second time I tried the
experiments, I did them by myself.
