4th Graders Build Circuits!
††††††† What is the difference between parallel and series circuits?† The 4th graders found out by making models of both and observing what happened when one light bulb was removed from the circuit.† We observed that when a light bulb was removed from the series circuit, the other light bulb went out.† We also observed that when a light bulb was removed from the parallel circuit, the other light bulb stayed lit.†
††††††† Our homes and schools are powered by parallel circuits.† If they were powered by series circuits, every time you turned on the lights, everything else would turn on too!†
