In this lesson, the students conduct an investigation to purify water. Students engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment.
One of the greatest problems facing society is the availability of clean drinking water. This lesson and activity provides an opportunity for student teams to complete the engineering design process related to water treatment used by practicing engineers, including constructing and testing their designs. See the related unit's Engineering Connection for further explanation.
After this lesson, students should be able to:
- Conduct an investigation to purify water
- Engineer a method for cleaning water
- Discover the most effective way to filter water
- Practice conducting a scientific experiment
