Scooby-Doo! A Science of Electricity Mystery: The Mutant Crocodile
surface I Jinkies said Velma That is one spooky monster Rouch said Scooby jumping off the rug like totally shocked Scoob exclaimed Shaggy The monster movie gave me monster powers It's static electricity Daphne explained Not monster powers Daphne's right said Fred Static electricity is electricity that collects on an object's
attract Electrical energy starts with an atom continued Velma Inside the atom's nucleus are protons and neutrons Protons have a positive electrical charge Neutrons have no electrical charge Electrons spin around the atom's nucleus added Daphne They have a negative electrical charge Charges that are the same such as two positives repel each other Opposite charges like a positive and negative charge
said When you dragged your socks across the rug electrons from the rug's atoms jumped into your socks atoms Fred said Those extra electrons gave you a negative charge And then you touched Scooby said Velma A bunch of your extra electrons jumped over to him and created a spark So like is static electricity the same kind of electricity that powers the TV Shaggy asked Not exactly said Fred Static electricity builds up in one place Dynamic electricity like in a television is the steady flow of electrons That flow of electrons is called an electrical current Electrons need something to flow through called a conductor Daphne said A conductor asked Shaggy I thought conductors told the orchestra how to play music Rusic agreed Scooby We're talking about conductors that help electrons flow Metals are good conductors Velma
