Electrical Circuits and Components

Year 6

Unit Overview

This project teaches children about electrical circuits, their components and how they function. They recognise how the voltage of cells affects the output of a circuit and record circuits using standard symbols.

In the Electrical Circuits and Components project, your child will consolidate their understanding of the components that make up a circuit, such as a lamp, cell, wire and switch. They will make a range of circuits and use symbols to draw circuit diagrams. Your child will learn about electric currents and measure the voltage of different cells. They will discover how cells produce electricity and research questions about cells and batteries. Your child will also learn how the voltage across a circuit affects the performance of different components. They will explore how programmable devices are used in everyday life and create a program to switch a light on and off via a light sensor. They will use the knowledge gained throughout the project to design, make and evaluate a programmable home device.


Creating exciting circuits using a range of scientific equipment in teams.


Writing a full experiment, from writing the question to the conclusion.


Electrical safety in the home. Applying your learning in your home and teaching your family members.

Unit Sequence: Learning Intentions

  1. Create circuits using a range of components and record diagrammatically using the recognised symbols for electrical components

  2. Compare and give reasons for variations in how components function, including the brightness of bulbs, the loudness of buzzers and the on/off position of switches.

  3. Investigate how the voltage across a circuit affects the brightness of a lamp

  4. Create a full investigation into conductors and insulators.

  5. Can a potato light a bulb?

  6. Discuss and evaluate electrical safety.

Scientific Enquiry: Investigations

  1. Can I create a circuit?

  2. Can fruit light a bulb?

  3. Can I measure voltage?


Create a full electrical investigation in to how electricity travels. Using all of the knowledge from the unit, we will use a range of complex equipment to create a fantastic circuit.
