Electricity (Simple Circuit)

Connect wire to the body casing of a dry cell

Connect wire to the positive and negative terminals of a dry cell

Connect wire only to the metal casing of a light bulb

Connect wire to the metal casing and metal tip of a light bulb

Dry cell provides energy

Dry cell has two terminal and these are where wire is connected to make complete circut

Expired dry cell still can provide energy

Dry cell connected through wire on the body casing to make complete circuit

If the circuit is complete, the light bulb will light up

Glass casing is where wire should be connected to make complete circuit

Metal casing and metal tip are where wires should be connected to make complete circuit

If the circuit is complete, the light bulb will not light up

Switch in "on" position is not a complete circuit

Switch in "off" position is not a complete circuit, and light bulb will not light up

Switch can be made using wood because it allow electricity to flow through

Switch can be made using metal because it allow electricity to flow through
