The Lawrence Hall of Science (LHS) at the University of California, Berkeley, in partnership with the Rutgers University Institute of Marine & Coastal Sciences, and the Curriculum Division of Carolina Biological Supply Company (Carolina Biological) propose to create an Ocean Sciences Curriculum Sequence, Grades 6-8 that will provide a major step toward achieving a coherent, comprehensive, nationally disseminated K-12 ocean sciences curriculum with NOAA as the lead sponsor of the entire series. The Ocean Sciences Curriculum Sequence, Grades 6-8 will be a powerful companion to the Ocean Sciences Curriculum Sequence, Grades 3-5 already available, and the recently published, NASA-funded GEMS Space Science Curriculum Sequence, Grades 3-8 (see http://www.lhsgems.org/CurriculumSequences.htm). The Sequence will be built in part on repurposing and updating existing instructional materials from the LHS Marine Activities, Resources & Education (MARE) and Great Explorations in Math and Science (GEMS) programs. The materials will provide teachers with standards-based tools for teaching basic science using the ocean as an integrating context. This project will create instructional materials that have potential to become the most widely used middle school ocean sciences curriculum nationwide. The materials will be: (1) grounded in current research on teaching and learning, (2) aligned to the Ocean Literacy (OL) Essential Principles and Fundamental Concepts, and national and state science standards, and (3) extensively field tested and evaluated to ensure their effectiveness and applicability nationwide. The Sequence will include print materials for teachers with inquiry-based learning activities, student readings and data sheets, pre-, post-, and embedded assessments, and readily available instructional materials "kits" that allow it to be adopted by whole school systems and/or states as part of their regular, mainstream science programs. The materials will provide classroom teachers with essential tools to advance ocean literacy and the discoveries of NOAA scientists. No comparable middle school ocean sciences curriculum is currently available.
