           1. Materials that allow electricity to flow through them easily are called

           ________________.


           2.________________ is a good conductor of electricity and is often used in
           electrical wires.


           3.Materials that do not allow electricity to pass through them are called

           ________________.


           4.Plastic, rubber, and wood are examples of ________________.


           5.A ________________ is used to safely cover metal wires and prevent electric
           shocks.


           6.Metals like copper, silver, and aluminium are examples of ________________.


           7.________________ is commonly used as an insulator in electric plugs and
           sockets.


           8.In an electric circuit, conductors help the ________________ to flow from the

           battery to the bulb.

           9.Water mixed with salt can act as a ________________ of electricity.



           10.________________ is an insulator that is often used in kitchen tools to protect
           from heat and electricity.


            QB. An inventor builds a robot but notices that its arms don’t work when trying
           to grab objects. He realizes he accidentally made them out of rubber.


           a. Do you think the robot’s arms will conduct electricity and work properly?

           Explain your reason.
