Next GEN Physical Science and Everyday Thinking

Crosscutting Concepts

Many of the CCs are addressed implicitly by having students employ them in the course of participating in the Next Gen PET activities/lessons. (A few selected CCs are addressed explicitly in some units and these are indicated in the Target Ideas for those particular units.) The table below shows the units in which students are expected employ each of the seven CCs in both formats of the Next Gen PET materials (X). (A unit key is available below the table.)

Code Narrative Unit Addressed
Crosscutting Concepts M SE EM PEF FM CF WS L PC CR
CC1 Patterns . Observed patterns of forms and events guide organization and classification, and they prompt questions about relationships and the factors that influence them. x x x x x x x
CC2 Cause and effect: Mechanism and explanation . Events have causes, sometimes simple, sometimes multifaceted. A major activity of science is investigating and explaining causal relationships and the mechanisms by which they are mediated. Such mechanisms can then be tested across given contexts and used to predict and explain events in new contexts. x x x x x x x x x x
CC3 Scale, proportion, and quantity . In considering phenomena, it is critical to recognize what is relevant at different measures of size, time, and energy and to recognize how changes in scale, proportion, or quantity affect a system’s structure or performance. x x x x x x x x
CC4 Systems and system models . Defining the system under study—specifying its boundaries and making explicit a model of that system—provides tools for understanding and testing ideas that are applicable throughout science and engineering. x x x x x x x x x x
CC5 Energy and matter: Flows, cycles, and conservation . Tracking fluxes of energy and matter into, out of, and within systems helps one understand the systems’ possibilities and limitations. x x x x x x
CC6 Structure and function . The way in which an object or living thing is shaped and its substructure determine many of its properties and functions. x x x x
CC7 Stability and change . For natural and built systems alike, conditions of stability and determinants of rates of change or evolution of a system are critical elements of study. x x x x
