Building a Series Circuit Guided Notes

Year 4 ScienceElectricity3 pages

About this worksheet

These Year 4 guided notes go with a lesson on series circuits, over three pages. Pupils fill fourteen gaps in four numbered sections and write two notes in their own words. They name a circuit, a loop and a current, then the cell, wires, buzzer and bulb. Next comes what happens to the bulb when a wire comes loose. The last section covers open and closed switches. Two diagrams show a working circuit and a broken one side by side. The answer key gives every word and a model answer for both notes. It follows the England National Curriculum for electricity.

Curriculum objectives covered

Electricity

โ€œConstruct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzersโ€

Section 2 names the cell, wires, buzzer and bulb, and Section 4 adds the switch. Pupils need real kits to build the circuit; the sheet is the written record.

Electricity

โ€œIdentify whether or not a lamp will light in a simple series circuit, based on whether or not the lamp is part of a complete loop with a batteryโ€

Section 3 compares a complete loop with a broken one and asks what the bulb does when the loop breaks.

Electricity

โ€œRecognise that a switch opens and closes a circuit and associate this with whether or not a lamp lights in a simple series circuitโ€

Section 4 links a closed switch to a lit lamp and an open switch to a gap in the loop. The wall switch note applies it at home.

What's inside this worksheet

1. What is an Electrical Circuit?

Three gaps for circuit, loop and current, and a labelled diagram of a cell, wires and a lit bulb.

2. Essential Circuit Components

Four gaps on the cell, wires, buzzer and bulb, then a note on why wires are copper inside and plastic outside.

3. Complete Loops and Breaks

A diagram labelled Complete Loop and Broken Circuit, then four gaps on terminals and what happens when a wire snaps.

4. Controlling Circuits with Switches

Three gaps on open and closed switches, and a note on what happens inside a wall switch at bedtime.

How teachers use it

With the kits

Give each pair a cell, two wires and a bulb. They build the circuit in the first diagram before they fill Section 1.

Fault finding

Set up three circuits, each with a loose wire or a gap, and let pupils find the fault before Section 3.

Safety talk

Use the copper and plastic note to talk about why pupils must never touch mains sockets or bare wires.
