Exploring the Oceans in 4D: Using Paleoceanography to Engage Students in Interdisciplinary Science

Abstract:

Recent collaborations between educators and scientists have helped to change the face of K-12 education and allow for the development of curricula that closely mimic real word scientific inquiry in ever more accessible formats. Here we capitalize on collaborations established by the Great American Biotic Interchange - Research Experience for Teachers (GABI-RET) and the Panama Canal Project - Partnerships in International Research and Education (PCP-PIRE) to create a series of hands-on activities that investigate the dynamic response of various components of the Earth’s system to changes in ocean gateways through time. In particular, we focus on the rise of the Isthmus of Panama and subsequent closure of the Central American Seaway that provide an opportune platform for the interdisciplinary teaching of multiple secondary education topics. Relevant themes include, but are not limited to, geologic time, dating techniques, plate tectonics, ocean circulation, climate, and the speciation/diversification of life. We have taken a versatile approach to these activities by simulating deep sea sediment cores, complete with 3D printed microfossils and related data, that allow students to actively apply the scientific method to simplified geologic archives, graph and assess evidence, and debate their findings in a project based format. The exercises themselves are designed to meet Next Generation and Florida State Science Standards for 6^th grade Earth Science and 12^th grade Environmental Management/Science classes, though the nature of the activities can be adapted to intermediary skill levels with relative ease. The project kit is designed for use in classrooms without ready access to computers or microscopes and the associated lesson plans/materials will be made available through the GABI-RET and PaleoTEACH websites.
