Investigation! Building a circuit • Investigation: Use the objects below to build a circuit. • List the components needed to make a circuit.

Investigation! Which is the best conductor? • Can all materials let electricity pass through? • Can some materials stop electricity? • Investigation: Use the objects below to test the best conductor.

Conductors and Insulators • Some materials do not allow electricity to flow through them. • These are called insulators. • Other materials allow electricity to flow through them. • These are called conductors. • Wires are made from materials that let electricity pass through them easily – copper or aluminum.

Amazing Fact! • Humans are very good conductors of electricity! • That’s why you have to be very careful when using electricity. • An electric shock can kill!
