Taking the Pulse of the Fraser

(Grades 6-9) Follow each step of the scientific method to conduct a water quality investigation. During this 2 hour workshop students observe and become curious about the Fraser River, do background research, construct hypotheses, test their hypotheses by doing experiments, analyze their data, draw a conclusion, and report their results. Students determine whether the current temperature, pH, and turbidity will or will not be above acceptable levels for salmon survival.
