Electricty a form of energy made when tiny parts move around in an atom; energy that can produce light, heat, sound and magnetism harness to make use of (the power of something) for a purpose needs things people must have to live. Humans need water to live wants things people would like to have. I want a Porsche to drive. Electric current amperes (amps) Static Electricity the movement of electrons through matter a measure of the amount of current in a wire Electricity caused by a build up of negative charges in one place and positive charges in another Lightning A flash of light caused by the release of static electricty between two clouds or from a cloud to the Earth Atom tiny particles that make up matter nucleus Center of an atom proton a particle that has a positive charge neutron a particle that has no charge electron particle that has a negative charge Circuit A closed path that allows an electric current to flow Series Circuit A singular path that allows an electric current to flow Parallel circuit A path with one or more branches that allows an electric current to flow Battery An energy source for a device Conductor a material, usually a metal, that allows an electric current to flow (transmits electricity) Insulator Material that does not allow an electric current to flow through it Magnet something that can attract other substances (like iron and steel) magnetism a force that pushes and pulls certain metals magnetic field an area around a magnet where magnetism can be felt attract to pull toward one another, as opposite poles of two magnets pull toward one another repel to push away, as similar poles of two magnets push away from one another north pole the end of a magnet where lines of force flow out south pole the end of a magnet where lines of force flow in power lines power cables that carry high-voltage electricity transformer a device that changes the voltage of an electric current voltage the amount of push that gets an electic current moving electromagnet a magnet that can be turned on or off by sending electricity through metal electromagnetism a combined force of electricity and magnetism
