The Dead Zone in the Gulf of Mexico
Students explore hypoxic (low oxygen) conditions in the Gulf of Mexico. In this ocean habitat lesson, students hypothesis, design and implement an experiment to explain the existence of the "Dead Zone" in the Gulf of Mexico.

Your Blooming Pond
Students model a pond system that becomes enriched with nutrients (fertilizer). They manipulate variables, make observations over time, and draw conclusions that may lead to further inquiry. They, in groups, simulate a pond environment.
Curated OER
Water Density Boundaries
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
