Electrical System

Grade 6

Conductors & InsulatorsEdit

  • Build the circuit shown above.
  • Place the different objects / materials between points A and B (choose from objects available)
  • Note your observations in the table below.

Object

Allows current through

Does not allow current through

Nail



Plastic pen



Ruler



Paper-clip



  • Materials that allow the flow of current are called Conductors
  • Materials that do not allow the flow of current are called Insulators

Answer these questions:

1. What happened when the nail was used to bridge the gap?
