Students started with a reading about the Great Ocean Conveyer Belt and some oceanography questions using the tables and diagrams in their notes.
Today we discussed sand and where it comes from, what its made of, what colors it can be, an how shape and size affect the texture. In Hawaii there are black, red, and green sand beaches that have been deposited from the weathering and erosion of volcanic rocks. In the Caribbean, you can visit white and pink sand beaches from the weathering and erosion of sand and coral. Students made observations of sand samples from Hawaii, Grand Cayman, Normandy France, Lake Anna, Lake Superior, California, and Virginia Beach.
The rest of class was spent working independently on the seafloor features surrounding the United States and reading and answering questions about underwater vehicles. Submarines are larger than submersibles and carry more people and can go longer distances. ROVs and AUVs are robots like remote-controlled cars, but go underwater. ROV's have a tether (cord) connecting them to power and AUVs do not.
Tomorrow students will review the material in Unit 1 for the test on Monday.

I think that submersibles are better than submarines even though they can carry less people because they can go deeper.
