Define a Problem
We made the gantt chart to help us track our progress and to see about where we should be on a certain day. We divided responsibilities so that we could get the project done faster.
We decided to split the responsibilities so that I would do more of the typing/writing parts and Jacob would do more of the building parts. also, so it would be even we decided to split the research parts evenly.

Test and Evaluate
The first test of our filter was, in fact, a successful one with the turbidity levels coming in at 43.5 NTU. This was under the desired level of 50, which meant that the filter had no problems, and worked quite well.
Refine
Since our filter worked on the first try, we did not have to make any revisions, nor did we have to run any other changes. If we did have to change anything, I would have probably added more tissues, as they seem to work better when there is more of them.
Conclusion
All in all this project was a great way for us to review the design process before the final project . It helped me relearn the design process, which will help with the presentation that we have to do for the final project. Next time I would have definitely worked on the weebly more throughout the the project, and not just towards the end. Although I was a little better this time around than I usually am, I could still have used my time more wisely. As for the teamwork, Jacob and I worked well together, and we split the workload pretty evenly. For next year, I don't really have anything to add as I feel that the projet does a good job of helping us review the design process.
