1. Explain why there might be differences between the calculated volume and the actual measured volume. What are the potential sources of error in this activity? What could be done to minimize errors? The equipment we used is precise and accurate; most of the measurements come close to be or are even exact. Some of the error might come from human error but using the equipment that is more precise would help
2. Explain how you chose the correct volumetric measuring instrument, such as a beaker, a graduated cylinder, a pipette, or a micropipette. To use instruments that gives a more precise measurement showing the exact amount of volume.
3. How did your choice of different volumetric measuring instruments potentially affect the accuracy and/or precision? The much larger equipment can measure the big amounts and the small amounts can be measured with the smaller equipment.
4. Considering the percentage of usable fresh water, what should we be concerned about when we use water? We should educate the public on efficient ways to use water because we need to preserver every drop we can and use it wisely.
5. Describe at least three other factors that might make availability of fresh water for human consumption a challenge in different parts of the world. Some areas have poor water processing which cause poor sanitation, dry areas with low rainfall that has low resources from where to get water, and how hard it can be to acquire it because some people cannot afford it.

Final summaryAfter our fermentation experiment we determined that Ethanol is not a viable alternative. The process of producing ethanol was conducted for five days. The fermentation included 4 pounds of Potatoes and 1 pound of Barley. At the end of the experiment we found that our distilled formation only had a low amount of 4.2% of Alcohol contents.
