This Grade 3 easy worksheet introduces the basics of electricity, including batteries, wires, bulbs, and simple circuits. Students fix sentence errors, complete fill-in-the-blank items, and decide if statements are true or false. The activities reinforce that a bulb needs a complete closed loop with a power source to light up, building a strong foundation for NGSS 3-PS2-3 science vocabulary and careful reading skills.
