This 250-word informational science passage introduces elementary students to the concept of electric current and how it powers everyday devices. Aligned with NGSS 4-PS3-2, the passage explains that electric current is the flow of tiny charged particles called electrons moving through materials like wires. Students learn how electric current carries energy from one place to another and can power devices that use electrical energy. The passage connects abstract concepts to familiar experiences by discussing electricity flowing through wires in homes to power lights, televisions, and computers. Audio-integrated features support diverse learners. The passage includes bold key vocabulary terms defined in context, concrete analogies comparing electron flow to water flowing through pipes, and age-appropriate explanations of cause-and-effect relationships. Supplementary activities include a multiple-choice quiz testing recall and comprehension, writing prompts requiring students to explain concepts and make real-world connections, and graphic organizers helping students visualize the flow of electrical energy. A simplified differentiated version ensures accessibility for all learners, while Spanish translations support English language learners. This comprehensive resource helps students understand fundamental concepts about electrical energy transfer and prepares them for deeper exploration of energy and circuits.

Electric current is the flow of energy through a wire. When you turn on a light or use a device that needs electricity, electric current is moving through wires to make it work. This flow of energy is what powers the things we use every day.
Think of electric current like water flowing through a pipe. Just as water needs a pipe to travel from one place to another, electric current needs a wire to flow through. The energy moves along the wire from where it starts, like a battery, to where it is needed, like a light bulb.
For electric current to flow, it needs a complete path called a circuit. A circuit is like a loop that connects the energy source to the device and back again. If there is a break in the circuit, the current stops flowing, just like water stops flowing if a pipe has a gap.
The current carries energy from one place to another. When the energy reaches a light bulb, it makes the bulb light up. When it reaches a motor, it makes the motor spin. The wire acts as the pathway that guides the energy where it needs to go.
Understanding electric current helps us see how electricity works in our homes, schools, and communities. Every time you flip a switch, you are completing a circuit and allowing electric current to flow and deliver energy to power your devices.
What is electric current?
Energy flowing through a wireWater in a pipeA type of batteryA broken circuit
What does a circuit need to work?
A break in the wireA complete pathOnly a light bulbNo battery needed
Where does electric current carry energy from?
From the light to darknessFrom water to pipesFrom battery to deviceFrom device to battery only
Why does current stop if circuit breaks?
The battery runs out quicklyNo complete path for flowThe wire gets too hotEnergy disappears completely
What happens when energy reaches a motor?
The motor lights up brightlyThe motor stops workingThe motor spins aroundThe motor makes no sound
How does flipping a switch help electricity?
It breaks the circuit completelyIt completes the circuit pathIt stops current from flowingIt removes the battery power
Electric current is similar to water flow.
TrueFalse
What is a wire's job?
To stop energy from movingTo store energy inside itTo guide energy where neededTo create new energy sources
