The EcoCasting Project is a set of hands-on inquiry activities focused on ecosystems, food webs, bioaccumulation, and invasive species designed for use in environmental science and biology classes in grades 9-12. The curriculum is aligned to Illinois state standards, the College Readiness Standards, and the National Science Education Standards. It addresses the following objectives:
• Using ecological models to investigate food web complexity
• Investigating PCB toxins and how they move through an ecosystem
• Investigating invasive species and how they disrupt ecosystems and change bioaccumulation patterns
EcoCasting is comprised of four major investigations, which may be done as stand-alone lessons or as parts of a larger unit.
The Office of STEM Education Partnerships (OSEP) at Northwestern University has created these materials to help students learn about the scientific observations, measurement techniques, and computer models used in an ongoing National Ocean and Atmospheric Administration (NOAA) Ecological Forecasting project. This curriculum is based on research conducted in Calumet Harbor, Illinois, where a NOAA team is developing more precise food web models to better predict PCB toxin levels in Great Lakes fish.
More information on the scientific research cited in EcoCasting can be found in Chemical Amplification in an Invaded Food Web: Seasonality And Ontogeny In A High-Biomass, Low-Diversity Ecosystem published in Environmental Toxicology and Chemistry, Volume 27, No. 10.
