KS3 - Circuits 1

Approx. lesson plan:

To understand that a power source provides energy as a flow of electric current and needs a complete circuit to flow.
To know how to draw simple circuit diagrams.
• To identify the circuit components
• To create a circuit
• To explain why the lightbulb lights up

Identify electrical devices in diagram -Car Phone Toaster TV Cooker Hoover Light Washing machine CD player Kettle Iron Fridge

Nothing to write / introduce the topic / electrical circuits

Give time to write title and date
Verbally explain keywords while/if they write them down.

Pichu = electron ‘pretend this baby Pikachu is an electron’
PD = amount of kick behind each electron. More volts = more electrons flowing.
Electrons carry charge

Students must form a circle. One is nominated as the bulb.
Teacher is battery. Give ‘charge’ (a sweet) to every 6th pupil. When charge reaches the bulb it waves.
Charge = energy.
Can travel faster than electrons – can pass it to each other instead if they are just shuffling.

Circuit diagram drawings
Construct circuit + test + draw
Recap Symbols on drawings / practically create and test circuits.
