Water Filtration Project: Make Your Own Water Filters
Students are asked to design methods to filter water using ordinary materials, while also considering their designs' material and cost efficiencies. They learn about the importance of water and its role in our everyday lives. They come to understand what must occur each day so that they can have clean water.

Clean water is not available in all parts of the world. Many people live with polluted water that is unhealthy to drink and bathe in. Civil, environmental , materials and mechanical engineers all contribute to developing technologies and systems to purify unclean water. Purifying water can be done easily if it is a small amount that is fairly clean, but larger amounts that are very polluted are much more complicated. Typical steps for full water treatment include aeration, coagulation, sedimentation, filtration and disinfection.
After this activity, students should be able to:
- Understand how filtration works.
- Create creative design methods.
- Problem solve given a design challenge.
- Apply mathematics (multiplication) reinforcement.
- Engage in teamwork to solve a challenge.
