WATER FILTER MINI PROJECT:
1. DEFINE A PROBLEM:
Gantt Chart -
The reason we made a gantt chart was so we would be able present our restraints in time and keep ourselves on track for what we needed to complete before we ran out of time for the project. Our responsibilities were divided for the same reason of time management. With both of us working diligently on separate tasks we will be able to complete all that's needed in our time frame.

2. BRAINSTORM:
Ideas-
Ideas-
- The use of a bottle to be able to see the materials inside.
- Charcoal because based on research it is a natural filter
- Rocks for a natural water fall filter
- cloth or sponge at the top and bottom to get larger dirt particles
Sketches-
3. RESEARCH AND GENERATE IDEAS:
Pros & Cons- some pros of these were that they didn't use a lot of materials and they are very easy to put together. Some cons would be that even though these are natural materials some like sand or rocks would need to be pre-cleaned before use.

4. EXPLORE POSSIBILITIES:
Test 1.
Sand- Test Results- Fast and effective Turbidity-87 Test 2.
Charcoal- Test Results- Fast but cloudy Turbidity- 400 + Test 3.
Rocks- Test Results-Fast but not effective alone Turbidity- 227 Test 4.
Cloth- Test Results- Catches large particles Turbidity-401 Test 5.
Sponge- Test Results- effective if compact Turbidity- 294 Test 6.
Pebbles- Test Results- Fast some what effective Turbidity- 256 5. SELECT AN APPROACH:
Decision Matrix- 6. DEVELOP A PROPOSAL:
7. MAKE A MODEL OR PROTOTYPE:
8.TEST AND EVALUATE:
Test 1 Turbidity- 18.4 Test 2 Turbidity- 19.8 Test 3 Turbidity- 54.6 Findings- Our first test was great and resulted in a very low turbidity. After our second test with an additional material our turbidity went up a little bit and the third test resulted in the turbidity rising a lot. we concluded that our coffee filter layers were not separating each material enough and water was going around each layer instead of through. Our plan is to make each filter layer thicker and able to keep the water from going around. 9. REFINE THE DESIGN:
We Refined our design by re making our entire design and trying to make sure the water wasn't going around the materials by placing the coffee filters more strategically. 10. CONCLUSION/REFLECTION:
The problem to solve was to make a water filter preferably cheap and resourceful for third world countries. We started by going through the design process. Defining the problem, brainstorming, researching and so on. Then we chose five material's to test, finding the turbidity and effectiveness of each. After that we chose the best materials and combined them to create a prototype. then tested that and redesigned to make it even more effective. Next time I would of like to had more time to fully test out even more materials. We had great team work, no problems. This project could be better next time if you went over all of the deliverables and refresh their minds of the design project. Also i think more time would be nice to complete every aspect of the deliverables. |
