Explore these resources to learn more about the natural and engineered processes that can help contribute to improved water quality.

Students act as engineers to design a basic solution to the water quality problems studied.

Despite seventy percent of the world's surface being covered with water, there is a potential shortage of this natural resource. Only a small percentage is fresh water and much of that is inaccessible or threatened. Learn about fresh...

Learn about the importance of water quality and environmental influences that reduce it.

In this activity, students' will use a pH sensor to check and compare the pH values of various water samples. They will understand the meaning and effect of pH and factors that affect pH.

Activity shows the link between land use activities within a watershed and water quality.

An introduction to an investigation of real-world problems to develop viable solutions to global access to clean water.

Students learn about global access to clean water and apply the engineering design process to develop a solution to purify water.

Students create a water purification system, and test it out to see how well it works to purify a water sample.

Students design a water purification system given certain constraints.

Students plan to present their water purification system at the end of a project-based learning exercise.
