Using many techniques including sonar, seismic profiling, and underwater research vehicles, oceanographers have mapped the topography of the ocean floor. We have discovered that it is much like the topography of Earth’s continents. It has mountains and volcanoes and great plains, however the mountains seem to be higher, trenches deeper, and plains more vast. This lesson will take place in an underwater setting. Students will discover the topography of the ocean floor while standing on it. Lesson will emphasize plate tectonics and its role in formation of both new oceanic crust and continental crust. A video will show the potential scenario that could occur if the Pacific Ring if Fire erupted! Lesson will also include examples of unique marine life seen in this benthic zone. Students will handle these organisms and discuss their unique adaptations. Field trip will include a submersible journey to the bottom of the ocean.
Examples of animals I used as IFXs to manipulate: giant squid, sperm whale, red sponges, viperfish, dumbo octopus, coral How Deep is the Ocean? https://www.youtube.com/watch?v=UwVNkfCov1k What If the Ring of Fire Erupted? https://www.youtube.com/watch?v=QniWayRs7pw Journey to the Deep 360 https://www.youtube.com/watch?v=NlPN9Ox_MIk
