Alcoholic Fermentation Lab

Kylie Johnson
Since we are regular human beings, of course we are going to consume a lot of energy in our lifetime. Most of the energy we consume comes from fossil fuels. Fossil fuels are a nonrenewable resource, and we are using these non-reusable ones uncontrollably. This is why we need to use more renewable resources. A way that we could do that is by the alcoholic fermentation of ethanol. Ethanol is a byproduct in corn, and it is one product that we use in fuel. Alcoholic fermentation is a process in which sugars such as glucose, fructose, and sucrose are turned into cellular energy and then produce ethanol and carbon dioxide as waste products. Research Problem:

We will be measuring alcoholic fermentation by counting the carbon dioxide bubbles that are being created per minute after forty minutes of our experiment. Hypothesis:
I believe that after 10 minutes of experimenting we will have multiple bubbles produced. Procedure Method:
When we experimented we set out all of our materials. Our materials were a fermentation bottle, one rubber stopper, one bubbler, one measuring beaker, 2 ml of yeast, 10 ml of warm water, and 30 ml of corn syrup. The first step we took was taking the measuring beaker, measuring 10 ml of warm water, and adding the 10 ml of warm water to the fermentation bottle. We then took the measuring beaker again, measured 2 ml of yeast, and added the 2ml of yeast to the warm water in the fermentation bottle. After that, we mixed both yeast and water gently until it was thoroughly dissolved. Then we took our measuring beaker again, measured 30 ml of corn syrup, and added the corn syrup to the mixture in the fermentation bottle. Soon after that, we swirled our mixture together. Then we put the rubber stopper on the fermentation bottle. We then took our bubbler and filled the bubbler with water until the water settled into the bottom and up to fill the two lines. We then inserted...
