Through the support of the National Science Foundation and a variety of sources, including the work of researchers, graduate students, curriculum developers, and high school teachers throughout the state of Illinois, The WaterCAPWS is able to share with you these supplemental curriculum modules, which can be used in combination or as stand alone lessons or labs.  Supplies and equipment, including a subject matter expert, are available for each of these labs if you complete a request form.  Some of the labs are also WebQuests, inquiry-oriented online learning units centered around the larger scientific or social problems that underlie each of these labs.
