The purpose of the NGSS (Next Generation Science Standards) Framework is to act as the foundation for science education standards while describing a vision of what it means to be proficient in science. It emphasizes the importance of the practices of science where the content becomes a vehicle for teaching the processes of science.
Each standard is a combination of these three dimensions...
-
Scientific and Engineering Practices are the skills and behaviors used by individuals in the pursuit of scientific inquiry and engineering design.
-
Crosscutting Concepts are the themes of science that provide an essential organizational schema for linking the domains together, making connections between various science concepts to create a coherent, scientifically based view of the world around us. They include: Patterns; Cause and Effect; Scale, Proportion and Quantity; Systems and System Models; Energy and Matter in Systems; Structure and Function; Stability and Change of Systems.

Disciplinary ideas are grouped in four domains: the physical sciences; the life sciences; the earth and space sciences; and engineering, technology and applications of science
