Description
This winning entry in the Museum's Young Naturalist Awards 2004 by Robyn, a 17 year old student from California, examines indicators of water composition and quality. Her essay reports on her research findings about how water temperature affects organisms and how thermal pollution starts a domino effect that harms aquatic life. She discusses her experiment design and her considerations in determining how to test her hypothesis.
