Define The Problem:
We divided up the work so that we can efficiently and effectively accomplish what we need to do. A way to do this was to create a gantt chart which evenly divided up the work between me and my partner. This is going to make sure that all the work gets done on time.
Team Responsibilities:
My responsibilities during this project have been to help in research and brainstorming, work on the weebly writing requirements, help in assembling the prototype and testing it.
James responsibilities during this project have been to help in research and brainstorming, attain the inexpensive materials that we have chosen to use, and help to assemble and test the prototype.

Test And Evaluate:
First Test: Turbidity value of 90
Second Test: Turbidity value of 74
Final Test: Turbidity value of 48
Our original "final design" was not even close to the turbidity value that we needed. It was about 40 away. We made a few revisions but nothing to major and got it down to a turbidity value of about 74 which was better but not good enough. We made some final major revisions and finally got the turbidity value to 48 which was below the value of 50 that we needed to reach.

Refine The Design:
Our original "final design" was not that similar wit our actual final design. Our actual final design is what we able to achieve a turbidity value of 50 with. At first we had several natural materials (such as sand charcoal and pebbles) and realized that that was not filtering the water enough. So after we tested out first prototype, we revised out new prototype to have more absorbent materials and less natural. We took away the sand we were using and added in layers of cotton filter, sponges and tissues. Those revised layers were what got us below the turbidity value of 50.

Conclusion:
I enjoyed this project and thought that it was a very creative way to get us following the design process. Me and James worked very well together and were able to get done what we had to do. At the very beginning we made a Gantt chart and actually figured out who would do what and when they would do it over the course of the week time limit we had. We had to construct and reusable water filter to filter dirty water (400 ntu) to clean water (below 50 ntu). We researched ideas in the internet and saw that natural materials such as carbon, rocks, sand and gravel were all commonly used in water filters. So we figured we'd give it a shot and try that out. Once we finished out first prototype with all natural materials, we tested it and it came no where close to what we needed it to be at. So we had to make some revisions. We decided to keep some natural materials but also that we needed more materials that would absorb the dirty water and release cleaner water. So we took away the sand that we were using and added sponge pieces and tissues along with cotton filters between each layer. This prototype gave us the turbidity value that we were looking for at 48 ntu. I think that our team work throughout this project was very good because we both had equal amounts of work to do and we both got our work done. If I were to do this again, I would research some more ideas before starting to hold anything. As for next years students? I wouldn't change anything, I like the way that this project was layed out and I liked what we had to do.
