The National Oceanic and Atmospheric Administration (NOAA) has developed a tremendous library of ocean-themed lessons that can be used in a variety of science settings. "Feeding in the Flow" is one of those activities; Its focus is on the 2006 Exploring Ancient Coral Gardens Expedition and the morphology of coral reefs. Your class examines related data on water flow and plankton capture by three different coral species. They graph the data and discuss what changes may impact results.
