Students from across Douglas County went hands-on Wednesday participating in the 20th annual Kids' Groundwater Festival in Alexandria.
More than 500 fourth graders absorbed information about local water resources and the importance of maintaining its quality. Groups rotated through several learning activities during the day, including an opportunity to put pond water samples under a microscope, and lessons on how wildlife are affected by water quality.
Students also took in special presentations and displays brought in for the 20th anniversary of the festival.
Over the last 19 years, nearly 10,000 students have attended the water festival, which is made possible by donations from local businesses, organizations and agencies.
