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.
This resource appears to be designed to build towards this performance expectation, though the resource developer has not explicitly stated so.
Comments about Including the Performance Expectation
This lesson as written has students explore the effectiveness of different solar oven designs that use the sun to heat their oven. To more fully address the performance expectation, students should first explore the scientific ideas behind solar radiation and its transfer of energy to the Earth's surface via sunlight. Students would then have to apply their understanding of sunlight to the design of their solar cookers. Such investigations may include testing the effects of covering or uncovering the oven, using transparent or opaque materials, using materials of different colors, or testing conductors and insulators of heat. The more that student scientific understanding and student design play a role in the device tested, the more this lesson will meet the Performance Expectation.
