Investigating Streamflow in the Schuylkill River
This exercise is presented in a jigsaw format but can be easily scaled to lower grade levels, where students prepare and/or are presented just one graph from one location for one period of time. Note that once the data is accessed on the USGS website, the data can be downloaded to work with in Excel, or (as this exercise suggests) a data table can be printed off for students to create graphs from. To help students visualize the units in which streamflow is measured, cubic feet per second (cfs), I bring to class a 1 ft x 1 ft x 1 ft box to show them what a cubic foot looks like.
