Students complete nine sentences about the single path in series circuits, multiple paths in parallel circuits, and what happens when a bulb burns out in a series circuit. The matching activity connects battery, switch, conductor, and insulator to their specific circuit roles.
Matching components to functions while comparing series and parallel pathways builds the complete conceptual framework students need for circuit design reasoning.
Style:
Electricity and Circuits
Part A: Fill in the Blank
Write the missing word or number on each line.
1. In a series circuit, electricity follows one single path.
2. In a parallel circuit, electricity has two or more paths to follow.
3. If one bulb burns out in a series circuit, all the other bulbs go out.
4. If one bulb burns out in a parallel circuit, the other bulbs stay on.
5. The lights in most homes are wired in parallel circuits.
6. A string of old holiday lights that all go out when one breaks is a series circuit.
7. Adding more bulbs to a series circuit makes each bulb shine dimmer.
8. The unit used to measure electric current is the ampere.
9. A device that opens a circuit when too much current flows is called a fuse.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
battery
→ provides energy to push current
blocks the flow of electricity
switch
→ opens and closes a circuit
provides energy to push current
conductor
→ allows electricity to pass through
allows electricity to pass through
insulator
→ blocks the flow of electricity
opens and closes a circuit
