Students learn that a circuit needs a source, a path, and a load before electricity can do useful work.
What Makes a Circuit Work
What students learn
Students learn that a circuit needs a source, a path, and a load before electricity can do useful work. Start with so students hear the main rule before naming any parts.
Why it matters
Electricity becomes useful only when it can move in a complete loop. Watch to see the parts students will keep naming again in the next lessons.
Learn the idea
A battery provides energy, wires carry the current, and a bulb or other load shows when the circuit is complete. helps students see the loop come together in a short build.
Try it
Draw a circuit with a battery, two wires, and one bulb. Ask the student to point to the path the electricity would follow and to explain what would happen if the loop opened.
Parent guide
Keep the explanation short and concrete. Ask for the three parts, then ask what happens when one part is missing. That small check tells you whether the idea has stuck.
