Analyze postmortem photos to determine the cause of death of a sea otter. Conduct simulated lab tests for the presence of biological toxins. Interpret lab tests, maps, and photos to explain the source of the toxin that is killing sea otters. Use a food web diagram to explain how sea otters could have high toxin concentrations. Conduct simulated lab tests to determine the concentration of toxin that causes damage to human liver cells. Design a sign to provide information about health effects of an algal bloom and ways to avoid exposure.
Caution: Choking hazard- small parts.
