Description:
Using online resources, students invent a submersible with mechanisms to control temperature, air pressure, and oxygen supply, modelled after the DeepWorker submersible of The Sustainable Seas Expeditions, a five-year project of underwater exploration and discovery of the marine world. They take a virtual dive into the kelp forest of California's Monterey Bay to see some of the things theyâd study if they were to go on a DeepWorker dive. Next, students devise strategies for taking underwater inventories of marine mammals or invertebrates, considering methods and equipment. They conduct online investigations of sea turtle movements; the Great American Fish Count count; and sonar.
