A Picture card
Sound card Quick practice

A glowing bulb changes electrical energy into light and heat energy.

energy change

Ask what form of energy goes in and what forms come out.

Example: Energy changes form inside the bulb.

A Picture card
Sound card Quick practice

A simple circuit needs a cell, wires, and a component such as a bulb in a complete loop.

circuit rule

Electric current flows only when the path is complete.

Example: A broken circuit will not work.

I Picture card
Sound card Quick practice

If a wire is removed, the bulb goes off because the circuit is open.

cause and effect

Open circuits interrupt the flow of current.

Example: The missing wire breaks the path.

Science habit: When a circuit fails, check the complete path before changing several parts at once.

troubleshooting step

Testing one thing at a time improves reasoning.

Example: Systematic checking helps explain why a circuit works or fails.
