Poll

Ghanim turns the lights on in his house. Looking at the lights, he begins to wonder how the charges are moving through the bulb. Which statement best describes how the charges move through the bulb?

• The bulb uses up the charges in producing light

• Charges clash in the bulb and produce light

• hen there are charges in the bulb, light is produced

• When charges pass through the bulb, light is produced

Understanding Simple Circuit

• 1) Battery

• 2) Wire

• 3) Switch

• 4) Light bulb

Multiple Choice

Why do we need a battery in the circuit?

• A battery is a source of energy

• A battery is an organizer of the circuit

• A battery is a transformer

Multiple Choice

Why do we need a wire in the circuit?

• The wire is a transport path for the electrons

• The wire generates extra electrons

• The wire switch the bulb On & Off

Multiple Choice

Why do we need a switch in the circuit?

• To turn the circuit On & Off as needed

• To generate more electrons

• To push electrons faster in the wire

Using Jamboard

Create a simple circuit

Open and Closed Circuit

Open circuit = is a circuit that is not complete and no electric energy flows through it.

Closed circuit = is a circuit that is complete and electric energy flows through it.
