MS-PS3-3 Energy
Students who demonstrate understanding can: Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.*
Clarification Statement: Examples of devices could include an insulated box, a solar cooker, and a Styrofoam cup. Care should be taken with devices that concentrate significant amounts of energy, e.g. conduction, convection, and/or radiation.
Assessment Boundary: Assessment does not include calculating the total amount of thermal energy transferred.
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Energy and Matter: The transfer of energy can be tracked as energy flows through a designed or natural system.	Constructing Explanations (for science) and Designing Solutions (for engineering): Constructing explanations and designing solutions in 6–8 builds on K–5 experiences and progresses to include constructing explanations and designing solutions supported by multiple sources of evidence consistent with scientific ideas, principles, and theories. Apply scientific ideas or principles to design, construct, and test a design of an object, tool, process or system.	Definitions of Energy: Temperature is a measure of the average kinetic energy of particles of matter. The relationship between the temperature and the total energy of a system depends on the types, states, and amounts of matter present. Conservation of Energy and Energy Transfer: Energy is spontaneously transferred out of hotter regions or objects and into colder ones. Defining and Delimiting an Engineering Problem: (secondary to MS-PS3-3) The more precisely a design task’s criteria and constraints can be defined, the more likely it is that the designed solution will be successful. Specification of constraints includes consideration of scientific principles and other relevant knowledge that is likely to limit possible solutions. Developing Possible Solutions: (secondary to MS-PS3-3) A solution needs to be tested, and then modified on the basis of the test results in order to improve it. There are systematic processes for evaluating solutions with respect to how well they meet criteria and constraints of a problem.
