This is a game I use quite often when explaining basic circuitry to school students. Each student gets assigned a component from an electrical circuit, then gets to his position and waits for his/her turn to reenact his part in an electrical circuit.

I will give an example of reenacting a simple switch circuit. It is a nice example to make students feel what polarity and DC means, and what is happening inside a circuit.

Roles:
– one Battery
– one LED
– Switch
– Electrons (the rest of the students)

Materials:
– labels for each role (you can use masking tape and eding)
– additionally: “+” and “” signs for Battery and LED. (stick them to the back of each hand)

Action:


Battery and LED go into the middle of the room and take each others hands, keeping attention at the right polarity! (Each hand is assigned with either + or – ). The moment both pairs of hands touch correctly the Electrons start to run around Battery and LED  in the right polar direction. Next: Extend the circuit with the Switch. Make sure everybody notices that the switch has no specific polarity. One the circuit of three students is closed – the Electrons start running again. When the Switch releases one of its hands – all Electrons have to stop immediately! Repeat several times – for the fun of it.

This game is inspired by an impromptu performance on “How to explain electromagnetism to a 5-year old” at the summercamp 2017, and works incredibly well. You can extend it to explaining pretty everything! E.g. use multiple LED-students to explain series and parallel connections. Or reenact a short-circuit and let the Battery-actor pretend he/she’s on fire.
