Your students become the circuit in this active, energetic demonstration that has them passing “electrons” to each other.
Get your students on their feet and in a large circle, with an arm’s length between them. While this activity seems simple, it will test the concentration skills of your students as they work to pass and receive balls at the same time. The rule here is that each student should have one ball, and only one ball, in their possession at any moment.
In this activity, the balls represent electrons that flow through a wire, represented by the students.
Gather the class and discuss the components of a circuit, and ask your students to identify those components in your demonstration. Encourage discussion around the fact that there are always electrons in conductive materials, but if the electrons aren’t moving, the light won’t go on.
An electric circuit provides a continuous path for electricity to flow through. There are three parts to an electric circuit:
The energy source provides power to the circuit, while the load makes use of the energy available. The conductor connects the energy source to the load and provides a path for the electrons to flow.
A switch can also be included as a means to open and close the circuit, controlling the current. When an electric current enters a load it converts that electrical energy. A light bulb converts electricity into heat energy and light energy.
Circuit diagrams use a universal set of symbols, so can be understood anywhere in the world. The symbols also make it easier to draw complicated circuit diagrams showing different components.
