You do not need to make it drinkable during this design. You will begin with a water sample that has visible dirt, mud, or other contaminants. You will design a way to filter the water and evaluate your design.

You will not be able to test for microorganisms or to filter them out during this design process. Do not test the water by drinking it. Important: Do NOT drink the water in your experiment. Materials "Swamp" water (You can get this from an outside source like hole in the ground, puddle, lake, river, swamp. Or, you may add dirt and sediment to tap water.) The starting sample should have visible dirt or sediment.

You may use any household materials for your water filtration system. Here are some suggestions: · Cheesecloth · Coffee filters · Cotton balls · Funnel · Old t-shirt · Pantyhose · Sock · Water bottle Planning for Design One Use this space to write out the plan for your water filtration design. List the materials you will use and how it will work. Use complete sentences and detailed examples. You may include sketches or diagrams.

Water before filtration Water after filtration Description of appearance Description of smell or other physical characteristics Rate the visible cleanliness of the water on a scale of 1 to 10, with 10 being the cleanest. Feedback Consult a peer or a family member about ways your design could be improved. Describe the feedback and provide the name of the reviewer.

These are only suggestions that you can use to plan for Design Two. Use complete sentences and detailed examples. Planning for Design Two Use this space to plan out how to improve your water filter. Based on the feedback you received, what part are you trying to improve? Why did you make the changes that you did?

Use complete sentences and detailed examples. You may include sketches or diagrams. Data for Design Two Use the data and feedback from your first design to make changes to your water filtration system. Test your new design. Record the appearance and smell of the "swamp" water before and after filtration.

Infections and Health Activity Worksheet

Introduction

Contaminated water poses significant health hazards, particularly regarding the transmission of infectious diseases. Among various pathogens, those that thrive in unclean water (like giardia and cholera) can lead to severe health consequences (World Health Organization, 2020). This project aims to design, test, and improve a water filtration system utilizing household materials to remove visible contaminants such as dirt, sand, and other sediment from water samples resembling "swamp" water. This exercise will simulate real-world problem-solving in the face of waterborne diseases, leveraging the scientific method.

Purpose

The main objective of this project is to filter out particles from a contaminated water sample without making it drinkable. The aim is to create an effective filtration system using everyday items. Specifically, we will use various filtration materials to assess their efficacy in removing dirt and other debris.

Planning for Design One

The following materials will be utilized for the initial design of the filtration system:
1. Cheesecloth: To act as a primary filter that captures larger particles.
2. Cotton balls: To trap medium-sized particles.
3. Coffee filters: To capture smaller sediment.
4. Funnel: To facilitate the water flow from the filtration system into a collection container.
5. Plastic bottle: To serve as the filtering unit, where the filtration layers will be arranged.
Process:
1. Cut the plastic bottle in half, using the top half as a funnel.
2. Line the funnel with cheesecloth, followed by layers of cotton balls and coffee filters, in that order.
3. Pour the contaminated "swamp" water into the top of the funnel.
4. Collect the filtered water in a clean container below.

Data for Design One

Water before filtration:
- Description of appearance: The "swamp" water appeared brown and turbid, with visible floating debris, dirt particles, and a cloudy appearance.
- Description of smell: The water emitted a musty, unpleasant odor, indicating the presence of organic materials.
Water after filtration:
- Description of appearance: Post-filtration, the water appeared clearer with significantly reduced particulate matter but still carried a slightly murky tone.
- Description of smell: The smell was less potent, though still earthy.
Visible cleanliness rating: I would rate the visible cleanliness of the water at about 5 out of 10, indicating that a substantial amount of contaminants remained.

Feedback

I spoke with my family member, Sarah, about the initial design. She suggested adding more layers of cotton and coffee filters, as the initial number didn’t seem sufficient to capture finer debris. Furthermore, she recommended placing additional cheesecloth at the top to avoid overflow during filtration.

Planning for Design Two

For the second design, the feedback indicated that adding more layers would likely enhance filtration efficiency. Thus, the updated plan includes:
1. Increased layers: Three layers of cheesecloth instead of one, followed by two layers of cotton balls and two coffee filters.
2. Expanded filtration unit: Position multiple funnels or create a multi-chamber filtration system to further improve filtration time and catch more debris.
Sketch: (Here, include a rudimentary sketch of the new design with increased layers).

Data for Design Two

Water before filtration:
- Description of appearance: The water maintained a similar brown and muddy appearance as observed earlier, with a higher volume of visible debris.
- Description of smell: The smell remained musty and unpleasant, consistent with organic contaminants.
Water after filtration:
- Description of appearance: The appearance post-treatment showed noticeable improvement, with the water appearing lighter in color, although a hint of cloudiness persisted.
- Description of smell: The odor was significantly decreased, bordering on neutral, yet with remnants of earthiness.
Visible cleanliness rating: After filtering, the water’s cleanliness improved to a 7 out of 10.

Conclusion

1. Design One Results: The "swamp" water before filtering was dark brown and had a musty smell. After using the filtration system, it appeared lighter, though still not completely clear, and the odor diminished to an extent, but was still noticeable.
2. Changes Made: I added more layers of cheesecloth and filters as suggested, which directly addressed the initial inefficiency in capturing finer particles.
3. Feedback Impact: Sarah’s advice helped inform the changes I made to my filtering system. Her suggestion to increase the layers proved beneficial, as demonstrated in improved results.
4. Design Two Results: The post-filtration water appeared clearer and had a reduced odor compared to the first design, moving from a messy brown to a more acceptable, slightly murky color.
5. Learning Outcome: Through this exercise, I learned the importance of iterative design, where improvements are made based on feedback and observable results. The process underlines the necessity of continuous testing and adjustment in addressing practical problems, echoing principles found in the engineering and scientific community (Duncan et al., 2021).
