AAAS and BSCS are collaborating to develop and study a curriculum unit that supports students' ability to explain a variety of biological processes…

AAAS and BSCS are collaborating to develop and study a curriculum unit that supports students' ability to explain a variety of biological processes such as 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…
