In June, the WELS2 project team held our second 1-week workshop for more than 45 Nebraska middle- and high school science teachers from over a dozen school districts at the University of Nebraska-Lincoln Innovation Campus.  Building on the previous summer workshop, teachers learned groundwater quality sampling techniques, used a computer-based, data-driven water balance model to explore regional water challenges, toured the Nebraska Water Sciences Laboratory, and developed curricular resources to use these tools in their own classrooms.  Teachers also had the opportunity to participate in the workshop as part of a UNL graduate course – SCIL 800 Experiential Learning in Food, Energy, & Water II.  A special thanks goes out to colleagues Trenton Franz, Dan Snow, and Dana Divine for working with teachers to utilize extraordinary UNL resources and tools, as well as to Tina Vo and Kate Gibson for helping plan and coordinate the workshop.  We greatly appreciate funding from the USDA-NIFA PD-STEP program and Improving Teacher Quality (ITQ) grant program through the Nebraska Coordinating Commission for Postsecondary Education, both of which have made this program possible.
