Weaving the threads of science is a metaphor used in the NRC Framework to represent the idea that science Ropehas components that are different but of equal importance. Students should know the three dimensions of the Disciplinary Core Ideas, Scientific and Engineering Practices and Crosscutting Concepts. This page highlights one of the three; the Crosscutting Concepts.

The NRC Framework, states it like this: “To develop a thorough understanding of scientific explanations of the world, students need sustained opportunities to work and develop the underlying ideas and to appreciate those idea’s interconnection over a period of years rather than weeks or months” (pg 26). The seven Crosscutting Concepts are a sort of glue for the whole discipline of science in that they can be thought of as holding the discipline together.

Figure 1 illustrates just three of the Crosscutting Concepts as they are relevant for this middle school standard.

The seven Crosscutting Concepts include:

  1. Patterns
  2. Cause and Effect
  3. Scale, Proportion and quantity
  4. Systems and system models
  5. Energy and matter
  6. Structure and function
  7. Stability and change.

In this example, there are connections to engineering, technology, and application of science, so in that case additional information is included. More detail about the Crosscutting Concepts can be found at the NGSS web site.

What does a complete NGSS standard look like? Every NGSS standard is made up of seven boxes with information related to that standard.

What other communication resources could be available for my state? There are several initiatives designed to support teachers with the implementation of the NGSS.
