HS-PS3-1 | Energy Transfer
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Clarification statement: Emphasis is on explaining the meaning of mathematical expressions for energy, work, and power used in the model.
Assessment boundary: Assessment is limited to basic algebraic expressions or computations; to systems of two or three components; and to work, power, thermal energy, kinetic energy, potential energy, electrical energy and/or the energies in gravitational, magnetic, or electric fields.
Note: This is a performance expectation for both HS Physics and HS Chemistry. The Disciplinary Core Ideas to focus on will vary based on whether the standard is being taught in a physics or chemistry class. For physics, the NYSED course map describes the focus as "Conservation of energy, thermal energy, endothermic and exothermic reactions overlap with Chemistry". For chemistry, the NYSED describes a focus of "Conservation of energy, thermal energy, endothermic and exothermic reactions".
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.

NGSS Dimensions
Performance expectation HS-PS3-1 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Using Mathematics and Computational Thinking
- Create a computational model or simulation of a phenomenon, designed device, process, or system.
- PS3.A: Definitions of Energy
- Energy is a qualitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system's total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.
- PS3.B: Conservation of Energy and Energy Transfer
- Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.
- The availability of energy limits what can occur in any system.
- Systems and System Models
- Models can be used to predict the behavior of a system, but these predictions have limited precision and reliability due to the assumptions and approximations inherent in models.
