This lesson was developed for middle school students using actual research on grass shrimp (Palaemonetes pugio) to illustrate the process of a scientific investigation. The research was conducted at Savannah State University and funded by the National Oceanic and Atmospheric Administration (NOAA) Office of Education through the Living Marine Resources Cooperative Science Center. The lesson had wide applicability and could be used as training on the processes of scientific inquiry, as part of the life science curriculum on crustaceans, or as part of an Earth science/environmental science curriculum.
