Fifth graders journeyed through the woods to collect water samples and find macro invertebrates living in the stream on campus. Students identified these critters under a microscope back in the lab and found them on a biotic index scale, which indicates the quality of the water based on the organisms found in the stream. The boys found many mayfly nymphs, stonefly nymphs, crawfish, and even a salamander. These organisms are intolerant to pollution which indicates that our stream has excellent water quality.
Mr. Torchio learned this technique of collecting water samples during his professional development experience at the Watershed Institute last summer and he says, "it was fun to share with the boys and increase their Water IQ!"
