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. Draw 2 more circuits

KS3 - Circuits 2 Has basic animated slides with examples of electron movement and principles of carrying charge. Follows from KS3 - Circuits 1 and leads on to concept of resistance.
