Project Management Summary:
For this project, we have a limited amount of time to meet all the requirements so it is necessary to divide the tasks so we finish on time. This is why we divided the project responsibilities so we stay on task and on schedule.

Explore Possibilities:
Select an Approach:
Based on the results, we've decided to try and use all filter systems in one together to try to lower the turbidity of the water.
Develop a Design Proposal:
Make a Model:
Test and Evaluate the Design:
Turbidity Value: 300 NTU
Our initial prototype takes a very long time to filter enough water to test, so we need to somehow make the water flow through the system faster. Also, our design has failed to filter the water to under 5 NTU. So we are going to completely change our design.

Refine the Design:
Through teamwork and talking with fellow classmates, I came to the conclusion that cotton and charcoal were essential to use, and that the cotton needs to be replaced after every test. The first test lowered the turbidity of the water to 17.2 NTU, and it has continued to decrease as shown in the data table above.
Communicate Processes and Results:
Conclusion:
This project turned out to be a lot harder than I had originally anticipated. I learned that filtering water is actually a difficult task and that we take that for granted. Drinkable water has a turbidity value between 0.5-1 NTU and my partner and I were struggling to even get the turbidity value under 300 NTU. I learned more patience because my partner and I didn't get the turbidity value to drop until day 3 of working on the filter. We redesigned our system at least 5 times throughout the first 3 days alone. This also caused me to work well with my teammate, Egor. We had a limited time to get a lot done so we had to divide tasks and communicate well in order to finish on time with a functional filter. If I were to complete this project again, I would have brought in my own materials right away, instead of using the same materials as the rest of the class. That way I would minimize making the same mistakes as my class and I wouldn't have to worry about using too much of any material. I would either create one more day to work on the project or allow groups of 3 for this project next year because I feel like if I had one more day, or one more person helping me, I could have gotten the turbidity level much lower. However, I has a great partner who figured out how to redesign the water filter to decrease the turbidity to about 2 NTU. Which is satisfactory.
