FOSS Module Summary

Module Summary – DSM Oceans

Students investigate our watery planet with a graphic model that compares water to land, salt water to fresh water, oceans to seas, and the Atlantic to the Pacific Ocean. Then, they get their hands wet investigating several ocean phenomena: saltiness, wave action, and currents. Students use ocean depth data to create a 3-D model of the ocean floor, make hydrometers to measure water density, and assemble a tidal dial to explore the ocean's rise and fall. Students model adaptive features of fish and marine mammals and use sea specimens to study an assortment of mollusks and other creatures of the intertidal zone.

In the Delta Science Reader Oceans, students explore the ocean, the great body of salt water that covers nearly three-fourths of Earth's surface. They learn about the composition of ocean water, features of the ocean floor, how ocean waters move, and how oceans affect weather and climate. They find out about the many resources the ocean provides. They also read about marine biologist Dr. Sylvia Earle and undersea explorer Jacques-Yves Cousteau. Finally, students learn about deep-ocean exploration.
