Electrical Circuits and Components

Year 6

Unit Overview

In this Science unit, we will learn all about electrical circuits, their components and how they function. By the end of the unit, we will be able to recognise how the voltage of cells affects the output of a circuit and record circuits using standard symbols. 

We will learn how a lamp, cell, wire and switch work together to make a circuit  and make a range of circuits and use symbols to draw circuit diagrams. We will learn about electric currents and measure the voltage of different cells. 

We will investigate how cells produce electricity and answer research questions about cells and batteries. We will also learn how the voltage across a circuit affects the performance of different components.  

Through exploring how programmable devices are used in everyday life, we will create a program to switch a light on and off via a light sensor. 


Competing with our friends to create exciting circuits using a range of scientific equipment in teams. 


Writing a full experiment: Big question, prediction, equipment, method, results and conclusion.


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

Unit Sequence: Learning Intentions

Working scientifically

Recording data and results of increasing complexity using scientific diagrams and labels, classification keys, tables, scatter graphs, bar and line graphs. 

Reporting and presenting findings from enquiries, including conclusions, causal relationships and explanations of and a degree of trust in results, in oral and written forms such as displays and other presentations.

Planning different types of scientific enquiries to answer questions, including recognising and controlling variables where necessary. 

Taking measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate. 

Using test results to make predictions to set up further comparative and fair tests. 


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.
