Online animation explains that different parts of an electric circuit make up a system. *4*Science lesson also provides limited sample questions at the end of the topic.*4**4**1*THE ELECTRIC CIRCUIT*2*Explains an electric circuit is a system made up of components and conductors.*4*Explains that some materials allow electric charge to flow through them - these are called electrical conductors.*4*Explains that metals like copper, iron and steel are examples of good electrical conductors.*4*Explains electrical insulators do not allow electricity to pass through them. Plastic, wood, glass and rubber are good electrical insulators.*4*Explains an electric circuit is made when the components and conductors are connected so that electric charge can flow through.*4*Explains an energy source can be a cell, a battery or the mains supply.*4*Explains the components use the electric energy to transform into other forms of energy.*4**4**4*Useful for teachers of science/physics.
