So many things run on electricity – televisions, computers, hairdryers, kettles, lights – but how does it actually work? How does it travel from the big power station all the way to your house so you can cool off with a fan or watch a DVD? Ms Frizzle and her class get the “insider’s view” of something we all take for granted.

Start With the Basics With Ms. Frizzle

As usual with the Magic School Bus series, events begin in the classroom, where Ms Frizzle explains how electrons in atoms get pulled away from the nucleus, and the stream of electrons generates an electric current. When the kids plug the fan into the wall socket and turn on the switch, the electrons “run” through the metal wire in the cord all the way into the fan’s motor and hey presto – cool air.

They make their own mini-power plant by wrapping copper wire around a magnet and attaching both ends of the wire to a meter which measures electricity. When the magnet moves, the current flows through the wire to the meter, and the needle on the meter registers the electricity flow. But in the middle of all the fun, the lightning storm causes a power cut, and of course Ms Frizzle is determined to find out how it happened.
