Those tiny organisms mean good water quality!

Mike Liston teaches in the Environmental Management program at Tolles Career and Technical Center. He recently took his environmental science students outside to check water quality in the creek on school property. The students did an initial check to practice collection and identification. “I find that if I get the students outside to do a practice run first, the students seem to get more out of the lab,” Liston noted.

To determine water quality, students check water chemistry and collect macro invertebrates. The Tolles creek has a silt bottom, so students need to be careful to not stir up too much sediment which makes identification difficult.

Liston was a participant in this summer’s Feed the World workshop, which he found helpful for classroom use. “Thanks to Ohio Corn and Wheat for the training experience and materials!” he said.
