Cotmanhay Junior School

Safe, Happy Learning




National curriculum content

  • Associate the brightness of a lamp or the volume of a buzzer with the number and voltage of cells used in the circuit
  • 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
  • Use recognised symbols when representing a simple circuit in a diagram


Lesson objectives

  1. Explain the importance of the major discoveries in electricity
  2. Create a circuit diagram using the correct symbols
  3. Describe how we can change the brightness of a bulb or the loudness of a buzzer
  4. Demonstrate how we can alter the current in a circuit
  5. Create a game that uses an electrical circuit
  6. Create a game that uses an electrical circuit
  7. Generate an explanation text


What we want children to know

  • How to represent a simple circuit in a diagram using recognised symbols
  • Which symbols represent each component in a circuit diagram
  • How voltage affects the brightness of a bulb or the volume of a buzzer
  • Key events and inventions in the history of electricity
  • That current is the flow of electricity around a circuit


What skills we want children to develop

  • Plan different types of scientific enquiries to answer questions
  • Construct simple series circuits
  • Take measurements, using a range of scientific equipment, with increasing accuracy and precision
  • Use test results to make predictions to set up further comparative and fair tests
  • Report and present findings from enquiries
  • Identify scientific evidence that has been used to support or refute ideas or arguments
