"To prepare students to disentangle the complicated environmental, social, and economic challenges exacerbated by the previous generation and propose effective solutions, they need to be taught the necessary knowledge and skills. Education for Sustainability (EfS) is one such modality. Organizations such as the Cloud Institute for Sustainability Education, Shelburne Farms, and the US Partnership for Education for Sustainable Development have opened the doors for EfS in the K-12 education system; however, curriculum to address these standards has not yet fully been developed. Furthermore, EfS curriculum that aligns to state and national standards needs to be written so that teachers can then use it in their courses and cultivate systems thinking skills in all learners. The primary objective of this project is to propose a high school level biology curriculum that uses an EfS lens to enhance core science content. A comparison of five EfS curricular frameworks was conducted and the Cloud Institute for Sustainability Education’s EfS Standards & Performance Indicators was selected as the primary reference for the sustainability lens of the forthcoming curriculum. The proposed high school biology curriculum focuses on two Next Generation Science Standards themes: Interdependent Relationships in Ecosystems and Natural Selection and Evolution. This curriculum integrates many EfS themes. The dynamics of systems and change and inventing and affecting the future are the two most prominently explored EfS themes in the curriculum."--leaf ii.
