Activity (Hands-On)Grades 3 - 5
The Dirty Water Project: Design-Build-Test Your Own Water Filters
In this hands-on activity, students investigate different methods—aeration and filtering—for removing pollutants from water. Working in teams, they design, build and test their own water filters—essentially conducting their own "dirty water projects." A guiding data collection worksheet is provided.

Civil, chemical and environmental engineers work together to make existing water treatment systems better, and to develop new water treatment systems. Some engineers design state-of-the-art seawater treatment system technologies that process ocean water cost-effectively for safe domestic use.
After this activity, students should be able to:
- Use sight and smell to identify pollutants in a water sample.
- Explore what types of pollutants are removed from water by aeration and filtration.
- Design, build and test a water filtration system.
- Explain the role of engineers in water treatment systems.
