ATOMS: Tiny particles that make up  everything around us. Atoms are so small that 12 trillion of them can fit in a grain of  sand. 
        CIRCUIT: A closed path or loop that is  needed for electricity to flow. Electricity will not flow if a circuit is open. 
        CONDUCTOR: A material that allows  electricity to flow through it easily. Water and metal are good conductors. So  is your body!  
        CURRENT: The flow of electrical charge, measured in amperage (“amps” for short). The amperage in an electric circuit is  like the amount of water that comes out when you turn on a faucet. 
        ELECTRICITY: A type of energy carried by  the movement of electrons.  
        ELECTRON: A particle that travels around  the nucleus at the center of an atom.  
        ENERGY: A property of many substances that  is associated with heat, light, electricity, mechanical motion, and sound. 
        INSULATOR: A material that does not allow  electricity to flow through it easily. Special rubber and special glass are  used as insulators. 
        VOLTS:   Short for “voltage,” a measure of the force with which electricity  flows. The voltage in an electric circuit is like the pressure that pushes  water out when you turn on a faucet. 
        WATTS:   A measure of the work that electricity does. Watts = Amps x Volts.  |
