Water quality in fresh water resources is an ever increasing problem in the world. This investigation is designed to allow the student to investigate many of the factors that affect water quality. The student will also gain practice in researching and understanding what raw data about a stream means relative to the stream s health. This investigation will help determine where rivers are healthy and where they are in danger. Once a problem is identified, then a solution can be explored.
Ecology is about the interactions of organisms with each other and their abiotic environment.
Studying an actual stream will help students understand ecological principles and give them a deeper appreciation of their own environment. Stream ecology is an interplay of many different factors. River hydrology will affect the health of the ecosystem. Pollutant concentrations will decrease as stream flow increases. Different organisms will be able to survive in different hydrological conditions and water quality standards.
