Simple Circuits

Grade 4 Science Worksheet - Challenge Me

NameDate

Circle the answer.

1.
Which group lists only conductors?
- wood, plastic, glass
- copper, rubber, steel
- copper, steel, aluminum
- aluminum, cloth, rubber
2.
A student puts a wooden craft stick across the gap in a circuit. The bulb stays dark. She says the battery is dead. What should she test first?
- a new bulb with the stick
- a second wooden stick
- a longer wooden stick
- a metal object in the gap
3.
This circuit has a closed switch and works. What does the buzzer give off?
- electrical energy back to the battery
- sound energy
- light energy
- motion energy only
4.
A hair dryer blows warm air. What does it change electrical energy into?
- motion only
- heat only
- light and sound only
- heat and motion
5.
Why does the wire in a circuit get warm when current flows for a long time?
- some electrical energy changes to heat in the wire
- cold energy slowly leaves the wire
- the wire stores light energy inside it
- the wire makes new energy of its own

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

NGSS standard: 4-PS3-2

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.

Questions parents ask

What is the most common mistake with simple circuits?

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

How can I help my child with simple circuits?

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