Unit Overview: Electrical circuits

National Curriculum

  • Identify common appliances that run on electricity
  • Construct a simple series electrical circuit, identifying and naming its basic parts, including cells, wires, bulbs, switches and buzzers
  • Identify 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 battery
  • Recognise that a switch opens and closes a circuit and associate this with whether or not a lamp lights in a simple series circuit
  • Recognise some common conductors and insulators, and associate metals with being good conductors.
  • 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.

What is static electricity?

In this lesson, we will be learning all about static electricity. We will learn how static charges occur and what happens when they are discharged. We will also be exploring how to create our own static charges with a balloon! If you have a balloon at home then you can use it for this lesson. If you don't then don't worry, you will still be able to watch the demonstrations and complete the lesson.

What are insulators and conductors?

In this lesson, we will learn what an electrical conductor and an electrical insulator are. We will conduct an investigation to see which materials are insulators and which are conductors. Finally, we will draw conclusions about the best material to make certain objects from, based on what we have learnt. You will need a piece of paper, a pencil and a ruler.
