To  make  a   light  go   on.

      To make a light go on you have to have closed  circuit. If the circuit is open the light will not come on. A close circuit is like a circle.
 

To make a light go on  you need a batery, light bud, two pices of wire about four inches long.
            Frist you put one wire on the  + side of the battery.Then put one of the wires on the black prat of the light blub. Then put one of the wires on the gray prat of the light blub. Then the light blub should light up.         by: James and Heather
