Innovating Science® - The Case of the Contaminated Lake

You are a scientist from the Environmental Protection Agency (EPA) visiting Lakeville for the annual water quality inspection of Pine Lake, however, something has gone awry. Someone intentionally polluted the lake! Perform chemical tests for contaminants on water and soil samples, analyze fibers, fingerprints, and footprints, and investigate suspect activity on social media in this environmental-forensic chemistry activity to uncover the culprit behind the crime. This kit contains enough materials for 15 groups of students. Teacher’s Manual and Student Study Guide copymaster included.
