The Next Generation Science Standards (NGSS) Crosscutting Concepts are seven fundamental scientific concepts that are applicable across all scientific disciplines. These concepts are:
-
Patterns: The recognition and analysis of patterns in natural and human-made systems, including patterns in space, time, and relationships between variables.
-
Cause and Effect: Understanding that events have causes and the ability to identify and analyze relationships between variables.
-
Scale, Proportion, and Quantity: Understanding that objects and events have size, relative position, and other quantifiable properties, and that changes in these properties can affect the relationships between objects and events.
-
Systems and System Models: The ability to analyze and understand complex systems, including natural and human-made systems, by breaking them down into their component parts and the relationships between them.
-
Energy and Matter: Understanding the conservation, transformation, and flow of energy and matter in natural and human-made systems.
-
Structure and Function: Understanding the relationships between the structure of an object or organism and its function, including how changes in structure can affect function.
-
Stability and Change: Understanding that systems can be stable or unstable, and that changes to a system can result in either stability or instability, and that these changes can be either beneficial or detrimental to the system.
The NGSS Crosscutting Concepts are important in education because they: Provide a framework for connecting scientific concepts across all scientific disciplines, helping students see the interconnectedness of scientific ideas and understand science as a unified body of knowledge. Encourage critical thinking and problem solving skills by emphasizing the analysis of patterns, cause and effect relationships, and the use of models to explain natural phenomena. Promote scientific literacy by helping students understand the fundamental concepts that underlie scientific investigation, and how these concepts apply to real-world situations. Foster a deeper understanding of scientific concepts and processes by encouraging students to think about the relationships between structure and function, energy and matter, and stability and change in natural and human-made systems. Enhance STEM education by providing a framework for integrating science, technology, engineering, and mathematics education and fostering a more integrated and interdisciplinary approach to learning.
Examples of NGSS Crosscutting Concepts:
-
Patterns: The regular patterns of day and night, the changing seasons, and the behavior of ocean tides.
-
Cause and Effect: The relationship between increased carbon dioxide levels and global warming, the effect of changes in diet on personal health.
-
Scale, Proportion and Quantity: The growth of a plant in response to sunlight and water, the relationship between an object's mass and its acceleration.
-
Systems and System Models: A model of a watershed showing how water flows through the system, the workings of the human circulatory system.
-
Energy and Matter: The transfer of heat from the sun to the earth, the reaction between baking soda and vinegar.
-
Structure and Function: The structure of bird wings and their function in flight, the structure and function of cell membranes.
-
Stability and Change: The stability of a food chain in a forest ecosystem, the change in climate over time.
