This resource is an update to the previous round of National Research Council publications that redefine what it means to be proficient in science. It provides key ideas on what it takes for teachers to provide high-quality science instruction and to support students in learning science effectively. It also provides a framework for thinking about the core elements of scientific knowledge and practice and provides evidence to support these key elements that ultimately form a foundation for science education in K-8 classrooms. The document can be read online free here; there is a charge for a pdf file download or a hard copy of the 405-page document.
