Much of modern biology has become increasingly chemical in character. Not surprisingly, students often have trouble understanding key ideas in biology because they lack foundational chemistry ideas. AAAS and BSCS are collaborating to develop and study a curriculum unit that supports students' ability to explain a variety of biological processes involving growth in chemical terms. The unit provides conceptual coherence between chemical processes in nonliving and living systems through the core idea of atom rearrangement and conservation during chemical reactions, which is critical for understanding how growth occurs while conserving matter. An initial draft of the unit was pilot tested at two schools in 2011. The results of the pilot test were used to revise the unit. In the spring of 2012, the revised unit and teacher materials was field tested. In this paper we will describe the iterative development process and the research that supports it. We will describe the Year 2 curriculum and, specifically, highlight how the curriculum enacts its four key design principles. Selected findings will be discussed that informed subsequent revisions during the final year of the project. (Contains 8 tables.)
