    Simple Electrical Circuit Simple Electrical Circuit Presentation Transcript

    • Simple Electric Circuit Project
      SC.O.4.2.19:construct simple electrical circuits
    • Materials Needed
      Wooden base to mount the circuit
      2 Light Bulbs
      1 lamp holder
      1 Battery holders
      1 Simple Switch (Known as knife switch)
      Screws used to mount the switch and the lamp holder
      Insulated solid copper wire (Gage 22
    • Steps to Construction
      Step One –
      Use screws to mount switch, battery holder and lamp to wooden base.
    • Steps to Construction
      Step Two –
      Using the wire make the circuit connections as shown . Please be careful loosing screws and stripping the end of the wires!
    • Steps to Construction
      Step Three–
      Place a D battery in holder, lower the switch and watch your light shine
    • Conductors and Insulators
      Identify conductors and insulators around you. It is important to know what materials are conductive and what materials are not. The test is simple. Open the switch and place the object between the poles of the switch. If the light comes on, then the object is conductive. You may try this with metals (coins, paper clips, nails, etc.) and non-metals (glass, plastic, stone, wood, etc.)
    • Definitions
      Conductor
      Insulators
      In a conductor (usually metal) many of the electrons are free to move around within the conductor therefore allowing electricity to pass.
      In an insulator (such as plastic, rubber, glass, etc) the electrons are not free to move around the entire object therefore not allowing electricity to pass
    • Make it simple!
      Conductors
      Insulators
      An insulator is something that does not let heat and electricity go through it easily. 
      If you slide down a plastic slide, like on our playground, it is very warm, but it will not burn you like a metal slide.  Plastic is a good insulator
      A conductor is something that lets heat and electricity go through it.
      Think of a hot summer day.  You sit on a shiny metal slide, OUCH! It's very hot and burns your legs! The slide is made of metal, it is a good conductor
    • Simple test
      Materials
      Directions
      Simple electric circuit
      Comb
      Fabric
      Metal Spoon
      Penny
      Rock
      Electrical Tape
      Copper wire
      Turn off switch
      Remove wire from switch going to lamp.
      Replace with additional wire
      Attach object to the two wires between lamp and switch
      Turn on Switch – be sure not to touch object
