Studies involving earth sciences, marine sciences and oceanography.

Think and Link to investigate three different ecosystem either the deep sea, coral reef or continental shelf. By connecting the dots students make a food chain to see how organisms in each habitat depend on each other.

In this lab activity, students use brine shrimp as a substitute for krill to investigate how changes in environmental factors affect behavioral responses of krill in the unique environment of Antarctica.
