Crosscutting Concept: Energy and Matter

Tracking energy and matter flow, into, out of, and within systems helps one understand their system’s behavior.

Objects may break into smaller pieces, be put together into larger pieces, or change shapes. (2.PS1.3)

Matter is made of particles. 

 

Matter flows and cycles can be tracked in terms of the weight of the substances before and after a process occurs. The total weight of the substances does not change. This is what is meant by conservation of matter. 

 

Matter is transported into, out of, and within systems. (5.LS1.1)

 

Energy can be transferred in various ways and between objects. (4.PS3.2, 4.PS3.3, 4.PS3.4, 5.PS3.1

Matter is conserved because atoms are conserved in physical and chemical processes. (7.PS1.5, 7.LS1.7)

 

Within a natural or designed system, the transfer of energy drives the motion and/or cycling of matter. (6.ESS2.4, 7.LS1.6)

 

Energy may take different forms (e.g., energy in fields, thermal energy, and energy of motion). 

 

The transfer of energy can be tracked as energy flows through a designed or natural system. (6.PS3.3, 7.PS1.6, 7.PS3.5, 7.LS2.3)

The total amount of energy and matter in closed systems is conserved. (CH.PS1.7)

 

Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system. (PS.PS3.3, CH.PS1.4, CH.PS3.3, PH.PS3.3, B.LS1.5, B.LS1.6, ES.ESS1.1)

 

Energy cannot be created or destroyed - only moves between one place to another, between objects and/or fields, or between systems. (PS.PS3.2, PH.PS3.2, PH.PS3.5, B.LS1.7, B.LS2.4, EN.LS2.4, ES.ESS1.2)

 

Energy drives the cycling of matter within and between systems. (B.LS2.3, ES.ESS2.3, ES.ESS2.6, EN.ESS2.3, EN.ESS2.6)

 

In nuclear processes, atoms are not conserved, but the total number of protons plus neutrons is conserved. (CH.PS1.8, PH.PS1.8
