Sehome High School
Using Submarine Landslides to Predict Slope Stability part of ERESE:ERESE Activities
Students use detailed bathymetric maps to find submarine landslides and compare the slope of these slides to the slope of hills near school and home. Students should have some experience interpreting topographic maps and basic graphing. The lesson can be used to build skills working with student collected data, discussion of slope stability (particularly with regard to seismic hazards) and increasing familiarity with the geography of ocean basins.
Introduction to the structure of the ocean using CTD data part of ERESE:ERESE Activities
Students use real CTD (Conductivity, Temperature, Depth) data and their own experiences to learn the basic structure of oceans. Depth, light, temperature, oxygen, salinity and pressure are considered. Students should have some graphing experience and some familiarity with the concept of dissolved oxygen in water. Grade Level: 9 -12 Duration of Lesson: 4 hours class time
Teaching the Carbon Cycle with a Consideration of Chemosynthesis (FeMO) part of ERESE:ERESE Activities
This series of activities introduces students to the concept of tracking carbon atoms using a geochemical budget model. The model is constructed using information from "Our Changing Planet" by Fred T. Mackenzie, 1998. The model is then altered by the introduction of human fluxes and evaluated using information from the National Geographic Society magazine article "The Case of the Missing Carbon". Finally, the model is re-evaluated considering the biomass and fluxes of chemosynthetic microbes as described by FeMO research at Loihi, Hawaii.
