engages students in understanding Biocomplexity, the complex fabric of relationships between humans and the environment. It incorporates an integrated framework to study the myriad relationships and reciprocal interactions that link human economic and social systems to natural systems of the planet. The curriculum consists of inquiry-based investigations designed around cases in urban, agricultural, tropical and polar systems. It builds on ecology, environmental science, human ecology, geography, economics and anthropology and helps students understand environmental land and resource use challenges increasingly confronting society. Because of its strong emphasis on science practices, disciplinary content, and cross-cutting concepts, the curriculum is very well aligned with the Framework for the Next Generation Science Standards.
