Our team's educational goal is to raise awareness and broaden overall understanding of the processes that lead to groundwater contamination for the general public. To do so, we created openly available interactive visualization tools to teach interested users about hydrologic concepts that control contaminant spreading. These tools overturn traditional teaching approaches with student-centered learning activities in which pupils first interact with visual data and gain a conceptual sense of the problem at hand, and then work on comprehending the math behind the problem.
