Grade 4 Science · Electricity and Magnetism
Build Grade 4 Science skills with five 10-question practice tests on circuits, conductors, insulators, switches, magnets, magnetic poles, electromagnets, motors, and electrical safety.
These Grade 4 Science practice tests help students explain how electrical circuits and magnetic forces work. Students identify conductors and insulators, build complete circuits, describe magnetic poles, explore electromagnets, and apply electrical safety rules.
For circuit questions, trace the complete path from the energy source through the conducting materials. For magnet questions, identify the poles and the materials involved. Always use safe practices around outlets, batteries, wires, and electrical devices.

4. Test
A 10-question Grade 4 Science practice test on circuits, conductors, insulators, switches, magnets, magnetic poles, electromagnets, and electrical safety.
Read each science situation and choose the answer that best explains the electrical circuit, magnetic force, energy change, or safety rule.
Please select an answer first.
Correct answer: A
The correct answer is A circuit with one path for electric current.
A series circuit has one continuous path for current.
Please select an answer first.
Correct answer: B
The correct answer is A circuit with two or more paths for current.
Parallel circuits provide multiple paths for electric current.
Please select an answer first.
Correct answer: C
The correct answer is The bulbs may become dimmer because the current is shared through one path..
Adding bulbs to one series path can reduce the energy available to each bulb.
Please select an answer first.
Correct answer: D
The correct answer is A wire is loose or the circuit has a gap..
A loose connection or gap prevents current from reaching the bulb.
Please select an answer first.
Correct answer: A
The correct answer is The switch completes the path so current can flow..
Closing the switch joins the circuit and allows current to travel.
Please select an answer first.
Correct answer: B
The correct answer is A metal paper clip.
Metal conducts electricity and can complete the path in a simple circuit.
Please select an answer first.
Correct answer: C
The correct answer is Plastic is an insulator that resists current..
An insulating material resists the movement of electric charges.
Please select an answer first.
Correct answer: D
The correct answer is Current may take a low-resistance path and produce too much heat..
A short circuit can allow a large current that overheats wires or batteries.
Please select an answer first.
Correct answer: A
The correct answer is A battery, conducting wires, and a bulb connected in a closed path.
The battery supplies energy and the wires and bulb form a complete conducting path.
Please select an answer first.
Correct answer: B
The correct answer is Different devices can have separate paths, so one device can stop while others continue..
Separate paths allow devices to operate more independently.
A closed circuit is a complete conducting path that allows electric current to travel from the energy source and back.
An electromagnet is a magnet made by running electric current through a coil of wire, often around an iron core.
