Cute but long animated cartoon shows the difference between positive and negative electrons, what happens when they are disrupted and subsequently transfer positive and negative energy. Electrons are represented as little cartoon creatures running from one place to another. A hand holding different types of metal ie, iron and copper are shown as examples of good conductors. A table of plastics, rubber, porcelain and glass are displayed as examples of poor conductors. Metals resistance to the flow of electrons is made an example of with shots of light bulbs and a woman turning on an incandescent lamp. Animated charts show the relationship between ohms, amperes and volts. Shot of an illuminated city boulevard at night. More quick shots of a train, streetlights, electrical towers, and air conditioners. Shots of power plants, magnets and an animated cartoon of the earth on its axis. More cartoons demonstrate electric currents in magnetic fields. CU of a subway , a clock, washing machine, an egg fryer, and a woman opening a refrigerator. MS of a boy and girl doing electrical experiments. Two conductors casts a stream of electricity between them.
