Abstract	For students in biology, chemistry, or environmental science, diatoms offer excellent insight into watershed health and human impact on the environment. Diatoms are found globally in virtually every habitat that has sunlight and moisture, including polar seas, tropical streams, and on moist soils and mosses. Studying diatoms as biological indicators immerses students in a compelling exploration of aquatic ecosystems. In this article, the authors present a novel and challenging set of activities that foster a greater understanding of scientific phenomena aligned with the "Next Generation Science Standards" (NGSS Lead States 2013). This investigation represents a two-year collaboration between a high school science teacher and a diatom researcher, who mentored projects developed by 10th-grade chemistry students in Portland, Oregon. Students designed an experiment to study water quality using diatoms. The article contains an outline of differentiation strategies, including group sizes, timing, and guiding questions for each activity. This lesson can be extended by using a scanning electron microscope (SEM) in the classroom. (ERIC).
