Radiation Transfer of energy by electromagnetic waves; i.e. waves can travel through space from the sun to earth. Conduction The movement of thermal energy from one thing to another through direct contact Electric Charge made up of Protons and Electrons; Protons have a positive electric charge; Electrons have a negative electric charge. Usually the two are balanced. Called an electric Force. Static Electricity Unequal Transfer of Protons or Electrons...Static Electricity is caused by an object with more protons than electrons. Electrical Current Movement of electrons Conductor Material that allows the flow of electrical current Insulator A meterial through which heat or electricity does not flow easily. i.e. rubber Electrons An electrically fully charged particle that moves around an atom's nucleus. Electrical Energy Energy that can power things. i.e. light Chemical Energy Energy formed by chemical reactions.. i.e. Mentos in coke Simple Circuit A simple circuit that electricity can flow through.... i.e. one light bulb can power a circle with many points of energy. Swtch Something that can be used to open or close a circuit Open Circuit A circuit that electricity cannot flow through Closed Circuit A circuit which electricity can flow through Series Circuit A circuit in which there is only 1 path Parallel Circuit 2 Circuits that are exactly across from each other Flow of Heat Energy Flows from warmer to cooler Thermometer An instrument whose size, shape or some feature changes when its temperature changes so it can be used to measure temperature. ElectroMagnet a magnet with a magnetic field formed by an electric current. How a electromagnetic energy works: Electric current travels through a wire, creates a magnetic field, moving the needle of a nearby compass Electric Circuit A steady flow of electric current through a complete loop. It needs a push, or force, to keep the current moving. Series Circuit (connected in 1 large loop) or Parallel Circuit (connected to energy source in a complete circuit; i.e. like a ladder). How does a light bulb work? uses thermal energy caused by an electrical current. Electric current passes through a wire, it heats up the wire, the wire gets so hot it glows and gives off light. It heats up because of "Resistance) Temperature Measure of how hot or cold something is How is Temperature Measured? With a thermometer marked in degrees. The greater the number of degrees, the higher the temperature. Heat Energy Moves from hot objects to cold objects. i.e. Heat from the hot pan melts the butter Heat energy that moves from one object to another when the two objects have different temperatures. Three ways Heat energy can move Conduction, Convection and Radiation
