Climate, Corals and Change
Introduce your science class to the Davidson Seamount expedition with images and discussion. Focus them on the deep-sea coral and changes that are occurring in the population due to a warming trend in the water temperature. A student handout lists oxygen isotope ratios over a 244 year period and relate this data to temperature. Although this lesson was written for middle schoolers, the complexity of the isotope involvement really makes it more appropriate for 9th grade and up.
