Carolina EcoKits®: LC50 Aquatic Toxicity
Grades 9-12. Students are introduced to static toxicity tests used by the EPA and other organizations to set water quality standards. During the lab, students prepare various concentrations of ammonium sulfate, a fertilizer component, and introduce Daphnia magna into their solutions. After 24 hours, students observe the mortality percentage of Daphnia in each concentration and determine the LC50 of ammonium sulfate. Kit accommodates a class of 30 students working in groups of 6.
