Water is essential for all living organisms. Students will explore how the natural water cycle and watersheds are connected to clean water access in cities.

How the natural water cycle and the natural watershed interact depends on gravity and topography. Students will grow to understand how that relates to where they live.

Students will discover that, in addition to gravity and topography, soil geology, vegetation, weather, and human development are factors in how the natural water cycle interacts with the watershed.

Abundance and diversity are key indicators of a healthy stream. Students will use real world data and research findings to analyze the health of stream communities and illustrate the concept of ecological interdependence.
