Unit 8 Science Fushion lessons 4-5

Electric motors are:

• a device that produces magentism

• a device that converts mechanical energy into electrical energy

• a machine that changes electrical energy into energy of motion

• an object that attracts iron and a few other metals

A magnet is:

• a machine that changes electrical energy into the energy of motion

• a device that produces magnetism

• a device that converts mechanical energy into electrical energy

• an object that attracts iron and a few other metals

An electromagnet is:

• a device that produces magnetism

• an object that attracts iron and a few other substances

• a machine that changes electrical energy into energy of motion

• a device that converts mechanical energy into electrical energy

A generator is:

• an object that attracts iron and a few other substances

• a machine that changes electrical energy into energy of motion

• a device that converts mechanical energy into electrical energy

• a device that current produces magnetism

a material that resists the flow of electric charges

• insulator

• conductor

a path along which electric charges can flow

• insulator

• conductor

• magnet

• circuit

a material that readily allows electric charges to pass through it

• insulator

• heat

• path

• conductor

When the switch in a circuit is open:

• The circuit is not complete (it does not work)

• The circuit is complete (it works!)

a circuit with several different paths for the charges to follow

• series circuit

• conductor

• parallel circuit

• electromagnet

has only one path for electric charges to follow

• insulator

• series circuit

• generator

• parallel circuit
