Instructional Ideas

• If available, have learners take apart an old water filtration system to see its components

Classroom Considerations

• Activity requires some materials
• A little prior preparation (making the polluted water) is necessary
  

Pros

• Provides additional information in the Engineering and Science Connections section
• Gives some guiding questions to use during discussion
  

Cons

• None
