Today we tested the conservation of mass. We took pop rocks, soda, vinegar, and baking soda. We took a 20 oz bottle of Dr. Pepper and one pack of pop rocks to test the reaction. We took a balloon and and funnel and pour the pop rocks into the balloon. Then we tried to create a reaction with the pop rocks and the soda. We place the balloon over the top of the bottle to see if we could trap the gas that it created to fill the balloon. Our attempt was not a success because the balloon was not tightly around the top so most of the gas escaped and the balloon did not fill like it was supposed to. We tried again by pour more pop rocks and a different balloon, but then the balloon broke. So we tried to get another balloon on there fast. That balloon still did not fill that big, but bigger than the first attempt. The next test we conducted was with the vinegar and the baking soda. This was more of a scientific “cliche” but we still conducted it because we knew that it would create a gas that would fill the balloon. This experiment worked a lot better. I think it was because we had out the balloon on better from learning from the first test. I also think that it worked better because it created more gas and there was more of a reaction. In the first test, the gas was already there but we just released it. In the second test, we created gas rather than it already being there.
