Teach your students and volunteer monitors all about natural water quality monitoring. All three categories of water testing are included on this CD: chemical, microbiological, and macroinvertebrate. Step by step instruction and lots of background material.
A 35 minute 2007 DVD film showing the real lives of benthic macroinvertebrates in the wild. These insects are far more than simply trout bait; they profoundly influence the aquatic ecosystem, and their presence is an accurate measurement of stream health and water quality.
This five unit curriculum teaches students through classroom lectures and activities that even though they may not live near the ocean, what they do everyday will affect the ocean.
