An object that attracts certain materials, such as iron or steel

magnetic pole


The end of a magnet










Magnets have two poles!

              A north pole and a south pole.


They react together.

                    What happens to like poles?

                              Answer: Like poles repel or push away from each other.

                    What happens to opposite poles?

                              Answer: Opposite poles attract or come together. 





It's fun to  build electrical circuits in class: both open and closed! 

                 What is a circuit? 

                    Answer: A circuit is the path along which electric charges move.


               What are the parts of a circuit?  Answer: There are 3 parts to a circuit:


     There is a source of electricity (A battery

     There is a path along which charges can move ( wires)

     There is some object that uses the electricity (light bulb)










We are learning how to identify materials as being conductors or insulators.

                    A paper clip is a conductor.  What are conductors?

                                   Answer: a conductor allows the electricity to pass through it.  



                    An eraser is an insulator.  What are insulators?

                                   Answer: an insulator does not allow the electricity to pass through it.


(rubber, plastic, wood)





If we have time, we will build circuits using a switch.  


               Why does the light go out when you lift the switch?

                         Answer: A switch  opens and closes the circuit. 

  •           When it is closed, the light bulb glows.
  • When it is open, the light bulb is out.
