Making a series circuit
I can use a circuit diagram to build a series circuit and then draw a circuit diagram of a completed circuit.

Lesson details
Key learning points
- The names and symbols of the basic components of an electric circuit.
- A series circuit is an electric circuit with one complete loop from one end of a battery to the other end.
- A circuit is built systematically following a circuit diagram in one direction, starting from any point.
- A circuit diagram is drawn systematically, following the circuit in one direction, starting from any point.
- Wires in a circuit diagram are drawn using a ruler for clarity, with no gaps that would indicate a break in the circuit.
Keywords
Series circuit - A series circuit is an electric circuit with one complete loop from one end of a battery to the other end.
Circuit diagram - A circuit diagram is a simple and clear way of showing the setup and components in an electrical circuit.
Circuit symbol - Circuit symbols are used to show electrical components in a circuit. They are simple to draw and easy to recognise.
Complete circuit - A complete circuit is one with no gaps, so electricity is able to flow round the circuit.
Common misconception
Pupils often think of a circuit diagram as a map of a circuit when, in fact, it is a stylised representation that is drawn in a particular way to increase its clarity.
Emphasise that the diagram shows the sequence of the components in the circuit, not the position. A component can be moved to a different place but still be in the same sequence.
