The mobile education exhibit was approved with a $55,000 budget in 2011. It took 8 months to convert a trailer for the exhibit. The trailer's graphics, aquifer model, and conversion each accounted for 15-33% of the budget. The exhibit focuses on watersheds, groundwater, permeability, and non-point/point source pollution. It targets 6th-8th graders and is used at about 60-80 community events per year. The most missed question on the 2011 STAAR test was about aquifers, showing the need for the exhibit's groundwater education.
