Students complete nine sentences about circuit breakers that shut off during overloads, static electricity charge buildup, and lightning as natural electrical discharge. The matching activity pairs series circuit, parallel circuit, fuse, and circuit breaker with their descriptions.
Distinguishing fuses from circuit breakers and connecting static electricity to lightning extends circuit knowledge to the safety devices and natural phenomena students encounter in everyday life.
Style:
Electricity and Circuits
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A circuit breaker automatically shuts off electricity when a circuit overloads.
2. Static electricity builds up when objects gain or lose electrons.
3. Lightning is a natural form of electrical discharge.
4. The positive and negative ends of a battery are called terminals.
5. Volts measure the amount of electrical energy a battery provides.
6. A complete circuit must include a source of energy, a load, and connecting wires.
7. Thick wires carry more current than thin wires.
8. Rubbing a balloon on your hair creates static electricity.
9. Never fly a kite near power lines because electricity can travel through the string.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
series circuit
→ one path for electricity to flow
reusable switch that stops excess current
parallel circuit
→ multiple paths for electricity to flow
one path for electricity to flow
fuse
→ thin wire that melts to break a circuit
multiple paths for electricity to flow
circuit breaker
→ reusable switch that stops excess current
thin wire that melts to break a circuit
