Building an energy-converting device means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A battery, bulb, and wires OR a warm/cool cup comparison setup; Paper for a simple energy-path note. 1. Say the goal of Building an energy-converting device in plain words once. 2. Adult shows one energy transfer (circuit lights, or heat moving to a cooler hand nearby) and names the path. 3. Child traces or describes three energy paths and says what changed. 4. Fresh check: one fresh energy-path description. Record and stop. Done: three energy-path notes with a before/after change. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- 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
“Could your child design and build a simple device — like a rubber-band car or a solar oven — that changes energy from one form to another?”
