The Next Generation Science Standards consists of three dimensions: (1) Disciplinary Core Ideas, (2) Cross-Cutting Concepts, and (3) Scientific and Engineering Practices. Whereas the "old" science standards emphasized the learning of content, the new science standards folds into the content common themes or principles that transect all scientific disciplines (cross-cutting concepts) and scientific thinking skills and practices that incorporate engineering design skills. The multi-disciplinary and integrated nature of science is emphasized in the new standards. NGSS also ensures that "Everyone engineers!" EUSD is excited to be in the midst of transitioning to NGSS.
