Chemicals used in water testing are hazardous and students should wear goggles while working with these.
Caution is advised when wading in the stream to avoid slipping.
Use topographic maps to better understand their surroundings. Perform chemical analysis of water quality and evaluate these results. Identify aquatic macro and micro invertebrates using field guides and evaluate mountain stream health based on these results. Generalize how water quality and other abiotic aspects of a stream affect the biotic aspects of that stream. Use scientific data to appraise the rivers where they live.
