Finer grained standards that are part of this one
Examples of devices could include electric circuits that convert electrical energy into energy of motion of a vehicle, light, or sound; batteries that convert chemical energy to electrical energy; and, a passive solar heater that converts light into heat. Examples of constraints could include the materials, cost, or time to design the device.
Constructing Explanations and Designing Solutions: 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.
