Define a Problem
We used the Gantt chart and dived up the responsibility so that we could be the most efficient and get the maximum productivity from the group.

Boiling water- the pro is that it creates almost pure water by creating steam which as almost no contaminates but sadly it is sometimes hard to collect and you also need a heat source
Physical filtering- is extremely cheap and can be effective but it can take a lot of time to filter
Chemical filtering- it kills most bacteria and viruses but doesn't get rid of dirt or other things of that nature

Explore Possibilities
Coffee filters and tissues prove to be the most effective at filtering the water by being able to bring the turbidity down large amounts which made it obvious that we would use them. The polyester did help some which was why we also used that in the design. We forgot to record the cloth which also helped some but not by a large amount.
Select and Approach
Develop a Design Proposal
Make a Prototype
Test and Evaluate the Design
When we first tested we had the coffee filter at the top which we observed filtered out a decent amount but left little to be filtered after the coffee filter had been passed and we ended up with 98.5 turbidity. We were still over the maximum of 50 as the turbidity which is why we decided to put the coffee filter at the bottom so or other components could filter out the larger particles and the coffee filter took care of the smaller particles.
Refine the Design
As said before we put the coffee filter at the bottom which led to multiple tests with a turbidity less than 50.
Conclusion and Reflection
The project overall was very fun. I felt more organized than I ever had pertaining to classes. I was able to carefully plan and strategically work at a pace in which both me and my partner were comfortable with. Also the planing led to barely and procrastination. In case of what could make this better for next year don't just let the students pick and change their special item whenever they want because it led to me being extremely hated by the class for awhile.
