4-PS3-4 - 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. Examples of constraints could include the materials, cost, or time to design the device.

Assessment Boundary - Devices should be limited to those that convert motion energy to electric energy or use stored energy to cause motion or produce light or sound.

4-PS3-4 - Apply scientific principles of energy and motion to test and refine a device that converts kinetic energy to electrical energy or uses stored energy to cause motion or produce light or sound.*

Clarification Statement - Sources of stored energy can include water in a bucket or a weight suspended at a height, and a battery.
