Time for a little review…. Let’s start with vocabulary! What type of electricity occurs when positive and negative charges no longer balance? HINT! HINT! HINT! You might get a ZAP! STATIC ELECTRICITY An electric charge in motion is called an …..? HINT! HINT! HINT! Think of the water in a stream. ELECTRIC CURRENT In what kind of circuit can an electric charge flow only in ONE path? In what kind of circuit can an electric charge flow in TWO or MORE paths? SERIES CIRCUIT PARALLEL CIRCUIT A force that acts on moving electric charge and magnetic materials that are near a magnet is called….? HINT! HINT! HINT! This is when you find a magnetic field! MAGNETISM A coil of wire with many loops through which an electric current passes is called an ….? HINT! HINT! HINT! Just combine our two key words! ELECTROMAGNET What else do we know about electricity and magnetism? Let’s find out! A ________ has a positive charge. An _______ has a negative charge. A ________ has no charge. PROTON ELECTRON NEUTRON Opposite charges …..? Like charges …..? HINT! HINT! HINT! Proton + Electron Proton + Proton Electron + Electron Opposites attract! Like charges repel! Magnets have two poles. What are they called? HINT! HINT! HINT! Think directions. Where is the attraction on a magnet the strongest? NORTH AND SOUTH THE POLES! What are the ONLY three materials that are magnetic? HINT! HINT! HINT! Think Bill Nye and metals. IRON NICKEL COBALT A material or object that allows electricity to flow through it is called….? Examples of these are…. CONDUCTORS Copper Water Iron A material or object which blocks the flow of electricity is called….? Examples of these are…. INSULATORS Wood Glass Rubber REMEMBER! Just because a material is a conductor DOES NOT mean that it is magnetic! AND NOW… Vocabulary I Vocabulary II Conductor or Insulator? CHARGE! Name That Circuit! 200 200 200 200 200 400 400 400 400 400 600 600 600 600 600 800 800 800 800 800 1000 1000 1000 1000 1000 Miss K. is putting up her Christmas lights. She notices that one of the lights in the strand is out. However, the rest of the bulbs stay lit. What kind of a circuit are these lights?
