The presentation will provide an overview of the CliMES (Climate Literacy through Epistemology of Scientific Modeling) project. This recently NSF funded four-year project aims to develop climate literacy among high school students through an emphasis on scientific modeling. Modeling is a core scientific practice emphasized in the Next Generation Science Standards (NGSS) in which models, or working representations of natural systems, are used in collaborative sense-making about system-specific phenomena. Using the curriculum developed through CliMES, students will learn about climate and climate systems through the use of a new web-based climate modeling suite EzGCM. ExGCM has been designed to provide non-scientists experiences with climate modeling.
