Simple Circuits

Grade 4 - Science - Building Confidence

Worksheet 1

  1. Circuit parts: solar cell -> wires -> buzzer -> solar cell. Why can the device work?

  2. A circuit fails because one wire is not touching the battery. Which fix should be tested first?

  3. Which material is most likely to act as a conductor in a simple circuit?

  4. Which material is most likely to act as an insulator?

  5. Circuit design: solar cell -> wires -> buzzer -> solar cell. What energy conversion happens when it works?

  6. Circuit parts: battery -> wires -> fan -> battery. Why can the device work?

  7. A circuit fails because the switch is open. Which fix should be tested first?

  8. Which material is most likely to act as a conductor in a simple circuit?

  9. Which material is most likely to act as an insulator?

  10. Circuit design: battery -> wire -> bulb -> wire -> battery. What energy conversion happens when it works?

About this worksheet

Simple circuits show that electrical energy transfers through a complete path and can be converted into light, heat, sound, or motion asks fourth graders to connect observations with an explanation, model, or design decision instead of choosing a fact from memory. Students may focus on the battery alone and miss that every part must connect in a loop for current to transfer energy to the device. This worksheet uses short investigations and evidence-based situations so students must read what happened, decide which science idea is being tested, and choose the answer that fits the title. Students identify complete and open circuits, choose conductors and insulators, explain energy conversions, and select fixes for circuit problems. Support versions use familiar objects and direct wording. Standard and challenge versions add closer distractors, fair-test language, and multi-step evidence. Ask your child to point to the measurement, diagram, map, or observation before answering. If the choice does not explain the evidence in the prompt, it is probably a distractor. That habit keeps science reasoning tied to data rather than guesswork.

What your child will learn

  • Recognize a complete circuit
  • Explain open circuit problems
  • Tell conductors from insulators
  • Describe electrical energy conversions

Worked example

A bulb lights when wires make a complete loop from the battery through the bulb and back to the battery.

Common mistake

Thinking a circuit works just because the battery is present, even when the loop is open.

Helpful hint

Trace the path from the energy source through the device and back again.
