This activity prepares the student to launch an investigation of the relationship between precipitation and Streamflow for a local watershed. It can enrich a study of the water cycle. Following the step-by-step instruction in this case study, students will locate, download, format, and finally graph one year of Web-based data for these two variables. Included is a graph that highlights the details of this often-complex precipitation-streamflow relationship and provides a context for launching a classroom discussion of the balance between surface runoff and infiltration during and after a rain event, soil porosity, soil saturate level, the influence of impervious surfaces in the basin, the impact of slope, wind and air temperature on watershed hydrology, and the influence of high or low vegetation. This chapter is part of the Earth Exploration Toolbook (EET). Each EET chapter provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data. Students should begin on the Case Study page.
