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.

Correct answer: B
The correct answer is The path is broken and current cannot travel through the whole circuit..
An open switch creates a gap in the circuit.
Please select an answer first.
Correct answer: C
The correct answer is When the battery, wires, and bulb form a complete conducting path.
The bulb lights when electricity has a complete path through it.
Please select an answer first.
Correct answer: D
The correct answer is Electric charges build up on the surfaces..
Rubbing can transfer charges and cause them to build up as static electricity.
Please select an answer first.
Correct answer: A
The correct answer is Keep water away from the outlet and ask an adult for help..
Water and metal can create dangerous paths for electricity, so adult help and dry hands are important.
Please select an answer first.
Correct answer: B
The correct answer is Electrical energy changes into light and some heat..
The bulb uses electrical energy to produce light and heat.
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.
