Conservation of mass investigation

In this lab we looked into how all mass is recycled and how mass cannot be destroyed merely change in form. This was demonstrated in both parts of the experiment we preformed today.
For this lab my hypothesis was "If we use baking soda and vinegar, it will produce more gas then if we use pop rocks and soda". For the first part of the experiment, we set up by putting the pop rocks in side of a balloon and putting the balloon over a bottle of soda (coke). We then let the pop rocks fall in to the soda, and watched the results. The pop rocks fizzled as they dissolved into the soda, and released CO2 which filled the balloon (somewhat). The CO2 barely managed to inflate the balloon a small bit.

-This is a diagram of what the first balloon looked like after it was filled with the gas produced by the pop rocks and soda.

















For the second experiment we measured out fifty mLs of vinegar into an empty bottle of soda. We then filled another balloon with baking soda. After we had put the second balloon over the soda bottle filed with vinegar, we tipped the baking soda in. This time the reaction happened much faster, and released much more CO2. It was just like I had said in my hypothesis, the baking soda mixture released more CO2, and filled the balloon much more efficiently. I made this educated guess based on the knowledge that teachers would most likely not use baking soda and vinegar for volcanoes, if it did not work better than pop rocks and soda.

- This is a picture of the two balloons side by side. The one on the right is from the second experiment (Vinegar and baking soda). The one on the left is from the first experiment (pop rocks and soda). As you can see there is a great difference between the amount of CO2 released in the two experiments.
