Science-minded Ziv leads the Streamside Discovery Crew—friends Nella and Omari—on a hands-on mission at Crystal Creek. With kick-nets, turbidity tests, dissolvable chemical strips, and a homemade hydro turbine, they uncover insects that signal clean water, chart pollution gradients, and even trace a factory’s nitrate leak. Together, they design wood-chip bioreactors and living shorelines to restore creek health, then shine at the county fair with interactive demos. This spirited tale shows young readers how rivers speak through chemistry, creatures, and currents—and how a curious crew can turn data into action, inspiring clear-water adventures for the future.
