⚡ Part 1: Circuit Components

1. What are the four main parts of a simple electric circuit?

Battery, wires, bulb, switch

Battery, motor, fan, cord

Plug, outlet, wire, lamp

Solar panel, battery, radio, antenna

2. What does the battery do in a circuit?

It makes light

It controls the flow

It connects the parts

3. What happens when you open a switch in a circuit?

The bulb gets brighter

The battery runs out

The electricity stops flowing and the bulb turns off

The wires get hot

4. Check all the safety rules we should follow when working with circuits:

Wear safety goggles

Keep the work area dry

Handle wires carefully

🔌 Part 2: How Circuits Work

5. Fill in the blanks using the word bank below:

Word Bank: closed, open, energy, conductor

When a switch is _____________, electricity can flow through the circuit and the bulb lights up. When a switch is _____________, the electricity cannot flow and the bulb turns off. Wires are good _____________ because electricity flows through them easily. A battery is the _____________ source for the circuit.

6. Explain what would happen if one of the wires in your circuit broke. Use complete sentences.

7. Draw a simple circuit diagram below. Label the battery, wires, bulb, and switch.
