Students learn about the pH scale and how it can be used to measure the health of a body of freshwater. Students then create their own experiments to test the pH of a local waterway. 

Inquire: Students engage in a meditation on the importance of freshwater and share their experiences and emotions. 

Investigate: Students learn about the relationship between pH, the health of bodies of freshwater, and climate change. 

Inspire: Students design and carry out an experiment to test the pH of a local waterway in order to assess its health.
