Ohm's Law: voltage, current, resistance 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 Ohm's Law: voltage, current, resistance 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.
