Building an energy-converting device
PROCEDURALApply scientific ideas to design, test, and refine a device that converts energy from one form to another
Mastery Evidence
- Design a device that converts one form of energy to another (e.g. electrical to light, kinetic to sound)
- Build, test, and identify what works well and what needs improvement
- Explain the energy conversion taking place in the device
Assessment Prompt
“Could [child] design and build a simple device — like a rubber-band car or a solar oven — that changes energy from one form to another?”
