"Water critters" is a one day session designed to measure stream and water quality through the collection and identification of indicator macroinvertebrates.
Participants will investigate the quality of the stream environment through the use of the
biotic index. The biotic index is a scale which indicates the type and abundance of
organisms in a representative sample of the environment to assess the quality of freshwater ecosystems. This live, one day session is designed for middle school and high school teachers and is aligned with the Arkansas K-12 Science Standards in Environmental Science.
TESS components addressed include:1A, 3A, 4E
