4-PS3-4 Energy
Students who demonstrate understanding can: Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.*
Clarification Statement: Examples of devices could include electric circuits that convert electrical energy into motion energy of a vehicle, light, or sound; and, a passive solar heater that converts light into heat, mousetrap cars, rubber band-powered vehicles. Examples of constraints could include the materials, cost, or time to design the device.
Assessment Boundary: N/A
Crosscutting Concepts	Science & Engineering Practices	Disciplinary Core Ideas
Energy and Matter: Energy can be transferred in various ways and between objects.	Constructing Explanations (for science) and Designing Solutions (for engineering): Constructing explanations and designing solutions in 3–5 builds on K–2 experiences and progresses to the use of evidence in constructing explanations that specify variables that describe and predict phenomena and in designing multiple solutions to design problems. Apply scientific ideas to solve design problems.	Conservation of Energy and Energy Transfer: Energy can also be transferred from place to place by electric currents, which can then be used locally to produce motion, sound, heat, or light. The currents may have been produced to begin with by transforming the energy of motion into electrical energy. Energy in Chemical Processes and Everyday Life: The expression “produce energy” typically refers to the conversion of stored energy into a desired form for practical use. Defining Engineering Problems: (secondary to 4-PS3-4) Possible solutions to a problem are limited by available materials and resources (constraints). The success of a designed solution is determined by considering the desired features of a solution (criteria). Different proposals for solutions can be compared on the basis of how well each one meets the specified criteria for success or how well each takes the constraints into account. Influence of Engineering, Technology, and Science on Society and the Natural World: Engineers improve existing technologies or develop new ones.
