Texas seventh grader builds robot to study pond ecosystems, advises officials

A seventh-grade student from Texas, Caden Terence Pohlkamp, has built an aquatic robot. The robot was used to collect water samples from 12 different retention ponds in the state. His research found ponds with diverse vegetation and fountains had higher oxygen levels, which are better for wildlife. Pohlkamp presented these findings to local officials to advocate for improved pond designs.
